Bagaimana cara membagikan gambar di Instagram di iOS?

Klien saya ingin membagikan gambar di Instagram, Twitter, Facebook.

Saya telah melakukan Twitter dan Facebook tetapi tidak menemukan API atau apa pun di internet untuk berbagi gambar di Instagram. Apakah mungkin untuk membagikan gambar di Instagram? jika ya lalu bagaimana?

Ketika saya memeriksa situs pengembang Instagram, saya telah menemukan Perpustakaan Ruby on Rails dan Python. Tetapi tidak ada dokumentasi Sdk iOS

Saya telah mendapatkan token dari instagram sesuai instagram.com/developer tetapi sekarang tidak tahu apa yang harus dilakukan langkah selanjutnya untuk berbagi dengan gambar instagram.

Akhirnya saya mendapat jawabannya. Anda tidak bisa langsung memposting gambar di instagram. Anda harus mengubah gambar Anda dengan UIDocumentInteractionController.

@property (nonatomic, retain) UIDocumentInteractionController *dic;    

CGRect rect = CGRectMake(0 ,0 , 0, 0);
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIGraphicsEndImageContext();
NSString  *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/test.igo"];

NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];
self.dic.UTI = @"com.instagram.photo";
self.dic = [self setupControllerWithURL:igImageHookFile usingDelegate:self];
self.dic=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];
[self.dic presentOpenInMenuFromRect: rect    inView: self.view animated: YES ];


- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
     UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
     interactionController.delegate = interactionDelegate;
     return interactionController;
}

CATATAN: setelah Anda mengarahkan ke aplikasi Instagram, Anda tidak dapat kembali ke aplikasi Anda. Anda harus membuka aplikasi Anda lagi

Berikut adalah kode yang diuji penuh untuk Mengunggah gambar + teks teks ke Instagram ..

file in.h

//Instagram
@property (nonatomic, retain) UIDocumentInteractionController *documentController;

-(void)instaGramWallPost
{
            NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
            if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not
            {
                NSData *imageData = UIImagePNGRepresentation(imge); //convert image into .png format.
                NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager
                NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it
                NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory
                NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"insta.igo"]]; //add our image to the path
                [fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image)
                NSLog(@"image saved");

                CGRect rect = CGRectMake(0 ,0 , 0, 0);
                UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
                [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
                UIGraphicsEndImageContext();
                NSString *fileNameToSave = [NSString stringWithFormat:@"Documents/insta.igo"];

                NSString *caption = @"#Your Text"; //settext as Default Caption
                self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"%@",caption],@"InstagramCaption", nil];
                [self.documentController presentOpenInMenuFromRect:rect inView: self.view animated:YES];
            }
            else
            {
                 NSLog (@"Instagram not found");
            }
}

- (UIDocumentInteractionController *) setupControllerWithURL: (NSURL*) fileURL usingDelegate: (id <UIDocumentInteractionControllerDelegate>) interactionDelegate {
    NSLog(@"file url %@",fileURL);
    UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
    interactionController.delegate = interactionDelegate;

    return interactionController;
}

ATAU

-(void)instaGramWallPost
{
    NSURL *myURL = [NSURL URLWithString:@"Your image url"];
    NSData * imageData = [[NSData alloc] initWithContentsOfURL:myURL];
    UIImage *imgShare = [[UIImage alloc] initWithData:imageData];

    NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];

    if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not
    {
        UIImage *imageToUse = imgShare;
        NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
        NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"Image.igo"];
        NSData *imageData=UIImagePNGRepresentation(imageToUse);
        [imageData writeToFile:saveImagePath atomically:YES];
        NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath];
        self.documentController=[[UIDocumentInteractionController alloc]init];
        self.documentController = [UIDocumentInteractionController interactionControllerWithURL:imageURL];
        self.documentController.delegate = self;
        self.documentController.annotation = [NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"Testing"], @"InstagramCaption", nil];
        self.documentController.UTI = @"com.instagram.exclusivegram";
        UIViewController *vc = [UIApplication sharedApplication].keyWindow.rootViewController;
        [self.documentController presentOpenInMenuFromRect:CGRectMake(1, 1, 1, 1) inView:vc.view animated:YES];
    }
    else {
        DisplayAlertWithTitle(@"Instagram not found", @"")
    }
}

dan Tulis ini ke .plist

<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>instagram</string>
    </array>

Anda dapat menggunakan salah satu skema url yang disediakan oleh Instagram

1. Dok resmi Instagram di sini

2. Bagikan dengan UIDocumentInteractionController

   final class InstagramPublisher : NSObject {
   
   private var documentsController:UIDocumentInteractionController = UIDocumentInteractionController()
   
   func postImage(image: UIImage, view: UIView, result:((Bool)->Void)? = nil) {
       guard let instagramURL = NSURL(string: "instagram://app") else {
           if let result = result {
               result(false)
           }
       return
   }
       if UIApplication.sharedApplication().canOpenURL(instagramURL) {
           let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent("instagrammFotoToShareName.igo")
           if let image = UIImageJPEGRepresentation(image, 1.0) {
               image.writeToFile(jpgPath, atomically: true)
               let fileURL = NSURL.fileURLWithPath(jpgPath)
               documentsController.URL = fileURL
               documentsController.UTI = "com.instagram.exclusivegram"
               documentsController.presentOpenInMenuFromRect(view.bounds, inView: view, animated: true)
               if let result = result {
                   result(true)
               }
           } else if let result = result {
               result(false)
           }
       } else {
           if let result = result {
               result(false)
           }
       }
       }
   }
   

3. Bagikan dengan pengalihan langsung

   import Photos
   
   final class InstagramPublisher : NSObject {
   
   func postImage(image: UIImage, result:((Bool)->Void)? = nil) {
   guard let instagramURL = NSURL(string: "instagram://app") else {
       if let result = result {
           result(false)
       }
       return
   }
   
   let image = image.scaleImageWithAspectToWidth(640)
   
   do {
       try PHPhotoLibrary.sharedPhotoLibrary().performChangesAndWait {
           let request = PHAssetChangeRequest.creationRequestForAssetFromImage(image)
   
           let assetID = request.placeholderForCreatedAsset?.localIdentifier ?? ""
           let shareURL = "instagram://library?LocalIdentifier=" + assetID
   
           if UIApplication.sharedApplication().canOpenURL(instagramURL) {
               if let urlForRedirect = NSURL(string: shareURL) {
                   UIApplication.sharedApplication().openURL(urlForRedirect)
               }
           }
       }
   } catch {
       if let result = result {
           result(false)
       }
   }
   }
   }
   

4. ekstensi untuk mengubah ukuran foto ke ukuran yang disarankan

   import UIKit
   
   extension UIImage {
       // MARK: - UIImage+Resize
   
       func scaleImageWithAspectToWidth(toWidth:CGFloat) -> UIImage {
           let oldWidth:CGFloat = size.width
           let scaleFactor:CGFloat = toWidth / oldWidth
   
           let newHeight = self.size.height * scaleFactor
           let newWidth = oldWidth * scaleFactor;
   
           UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight))
           drawInRect(CGRectMake(0, 0, newWidth, newHeight))
           let newImage = UIGraphicsGetImageFromCurrentImageContext()
           UIGraphicsEndImageContext()
           return newImage
       }
   }
   

5. Jangan lupa untuk menambahkan skema yang diperlukan di plist

  <key>LSApplicationQueriesSchemes</key>
  <array>
       <string>instagram</string> 
  </array>

Semoga jawaban ini akan menyelesaikan pertanyaan Anda. Ini secara langsung akan membuka folder perpustakaan di Instagram, bukan di Kamera.

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{
    NSURL *videoFilePath = [NSURL URLWithString:[NSString stringWithFormat:@"%@",[request downloadDestinationPath]]]; // Your local path to the video
    NSString *caption = @"Some Preloaded Caption";
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library writeVideoAtPathToSavedPhotosAlbum:videoFilePath completionBlock:^(NSURL *assetURL, NSError *error) {
        NSString *escapedString   = [self urlencodedString:videoFilePath.absoluteString];
        NSString *escapedCaption  = [self urlencodedString:caption];
        NSURL *instagramURL = [NSURL URLWithString:[NSString stringWithFormat:@"instagram://library?AssetPath=%@&InstagramCaption=%@",escapedString,escapedCaption]];
        if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
            [[UIApplication sharedApplication] openURL:instagramURL];
        }
    }];

jika Anda tidak ingin menggunakan UIDocumentInteractionController

import Photos

...

func postImageToInstagram(image: UIImage) {
        UIImageWriteToSavedPhotosAlbum(image, self, #selector(SocialShare.image(_:didFinishSavingWithError:contextInfo:)), nil)
    }
    func image(image: UIImage, didFinishSavingWithError error: NSError?, contextInfo:UnsafePointer<Void>) {
        if error != nil {
            print(error)
        }

        let fetchOptions = PHFetchOptions()
        fetchOptions.sortDescriptors = [NSSortDescriptor(key: "creationDate", ascending: false)]
        let fetchResult = PHAsset.fetchAssetsWithMediaType(.Image, options: fetchOptions)
        if let lastAsset = fetchResult.firstObject as? PHAsset {
            let localIdentifier = lastAsset.localIdentifier
            let u = "instagram://library?LocalIdentifier=" + localIdentifier
            let url = NSURL(string: u)!
            if UIApplication.sharedApplication().canOpenURL(url) {
                UIApplication.sharedApplication().openURL(NSURL(string: u)!)
            } else {
                let alertController = UIAlertController(title: "Error", message: "Instagram is not installed", preferredStyle: .Alert)
                alertController.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
                self.presentViewController(alertController, animated: true, completion: nil)
            }

        }
    }

Untuk iOS 6 dan di atasnya, Anda dapat menggunakan UIActivity ini untuk mengunggah gambar ke Instagram yang memiliki alur kerja yang sama menggunakan pengait iOS tetapi menyederhanakan pengembangan:

https://github.com/coryalder/DMActivityInstagram

ini adalah jawaban yang benar yang saya implementasikan dengan detail. Dalam file .h

 UIImageView *imageMain;
 @property (nonatomic, strong) UIDocumentInteractionController *documentController;

file in.m hanya menulis

 NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
 if([[UIApplication sharedApplication] canOpenURL:instagramURL])
 {
      CGFloat cropVal = (imageMain.image.size.height > imageMain.image.size.width ? imageMain.image.size.width : imageMain.image.size.height);

      cropVal *= [imageMain.image scale];

      CGRect cropRect = (CGRect){.size.height = cropVal, .size.width = cropVal};
      CGImageRef imageRef = CGImageCreateWithImageInRect([imageMain.image CGImage], cropRect);

      NSData *imageData = UIImageJPEGRepresentation([UIImage imageWithCGImage:imageRef], 1.0);
      CGImageRelease(imageRef);

      NSString *writePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"instagram.igo"];
      if (![imageData writeToFile:writePath atomically:YES]) {
      // failure
           NSLog(@"image save failed to path %@", writePath);
           return;
      } else {
      // success.
      }

      // send it to instagram.
      NSURL *fileURL = [NSURL fileURLWithPath:writePath];
      self.documentController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
      self.documentController.delegate = self;
      [self.documentController setUTI:@"com.instagram.exclusivegram"];
      [self.documentController setAnnotation:@{@"InstagramCaption" : @"We are making fun"}];
      [self.documentController presentOpenInMenuFromRect:CGRectMake(0, 0, 320, 480) inView:self.view animated:YES];
 }
 else
 {
      NSLog (@"Instagram not found");

 }

Pasti Anda akan mendapatkan hasil. Misalnya Anda akan melihat popover dari bawah dengan gambar instagram. Klik di atasnya dan bersenang-senang.

Saya mencoba ini di aplikasi saya dan berfungsi dengan sempurna (Swift)

import Foundation

import UIKit

class InstagramManager: NSObject, UIDocumentInteractionControllerDelegate {

    private let kInstagramURL = "instagram://"
    private let kUTI = "com.instagram.exclusivegram"
    private let kfileNameExtension = "instagram.igo"
    private let kAlertViewTitle = "Error"
    private let kAlertViewMessage = "Please install the Instagram application"

    var documentInteractionController = UIDocumentInteractionController()

    // singleton manager
    class var sharedManager: InstagramManager {
        struct Singleton {
            static let instance = InstagramManager()
        }
        return Singleton.instance
    }

    func postImageToInstagramWithCaption(imageInstagram: UIImage, instagramCaption: String, view: UIView) {
        // called to post image with caption to the instagram application

        let instagramURL = NSURL(string: kInstagramURL)
        if UIApplication.sharedApplication().canOpenURL(instagramURL!) {
            let jpgPath = (NSTemporaryDirectory() as NSString).stringByAppendingPathComponent(kfileNameExtension)
            UIImageJPEGRepresentation(imageInstagram, 1.0)!.writeToFile(jpgPath, atomically: true)
            let rect = CGRectMake(0,0,612,612)
            let fileURL = NSURL.fileURLWithPath(jpgPath)
            documentInteractionController.URL = fileURL
            documentInteractionController.delegate = self
            documentInteractionController.UTI = kUTI

            // adding caption for the image
            documentInteractionController.annotation = ["InstagramCaption": instagramCaption]
            documentInteractionController.presentOpenInMenuFromRect(rect, inView: view, animated: true)
        }
        else {

            // alert displayed when the instagram application is not available in the device
            UIAlertView(title: kAlertViewTitle, message: kAlertViewMessage, delegate:nil, cancelButtonTitle:"Ok").show()
        }
    }
}


 func sendToInstagram(){

     let image = postImage

             InstagramManager.sharedManager.postImageToInstagramWithCaption(image!, instagramCaption: "\(description)", view: self.view)

 }

Inilah jawaban yang benar. Anda tidak dapat langsung memposting gambar di Instagram. Anda perlu mengalihkan ke Instagram menggunakan UIDocumentInteractionController ...

NSString* imagePath = [NSString stringWithFormat:@"%@/instagramShare.igo", [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject]];
[[NSFileManager defaultManager] removeItemAtPath:imagePath error:nil];

UIImage *instagramImage = [UIImage imageNamed:@"imagename you want to share"];
[UIImagePNGRepresentation(instagramImage) writeToFile:imagePath atomically:YES];
NSLog(@"Image Size >>> %@", NSStringFromCGSize(instagramImage.size));

self.dic=[UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:imagePath]];
self.dic.delegate = self;
self.dic.UTI = @"com.instagram.exclusivegram";
[self.dic presentOpenInMenuFromRect: self.view.frame inView:self.view animated:YES ];

}

CATATAN: setelah Anda mengarahkan ke aplikasi Instagram, Anda tidak dapat kembali ke aplikasi Anda. Anda harus membuka aplikasi Anda lagi

Anda dapat melakukannya tanpa menggunakan UIDocumentInteractionController dan langsung membuka Instagram dengan 3 metode berikut:

Ini berfungsi seperti semua aplikasi terkenal lainnya. Kode tersebut ditulis di Objective c, jadi Anda bisa menerjemahkannya ke swift jika Anda mau. Yang perlu Anda lakukan adalah menyimpan gambar Anda ke perangkat dan menggunakan URLScheme

tambahkan ini di dalam file .m Anda

#import <Photos/Photos.h>

Pertama, Anda perlu menyimpan UIImage Anda ke perangkat dengan metode ini:

-(void)savePostsPhotoBeforeSharing
{
    UIImageWriteToSavedPhotosAlbum([UIImage imageNamed:@"image_file_name.jpg"], self, @selector(image:didFinishSavingWithError:contextInfo:), NULL);
}

Metode ini adalah panggilan balik untuk menyimpan gambar ke perangkat Anda:

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo: (void *) contextInfo;
{
    [self sharePostOnInstagram];

}

Setelah gambar disimpan ke perangkat, Anda perlu menanyakan gambar yang baru saja Anda simpan dan mendapatkannya sebagai PHAsset

-(void)sharePostOnInstagram
{
    PHFetchOptions *fetchOptions = [PHFetchOptions new];
    fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO],];
    __block PHAsset *assetToShare;
    PHFetchResult *result = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
    [result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {
        assetToShare = asset;


    }];


    if([assetToShare isKindOfClass:[PHAsset class]])
    {
        NSString *localIdentifier = assetToShare.localIdentifier;
        NSString *urlString = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@",localIdentifier];
        NSURL *instagramURL = [NSURL URLWithString:urlString];
        if ([[UIApplication sharedApplication] canOpenURL: instagramURL])
        {
            [[UIApplication sharedApplication] openURL: instagramURL];
        } else
        {
            // can not share with whats app
            NSLog(@"No instagram installed");
        }

    }
}

Dan jangan lupa untuk memasukkan ini ke info.plist Anda di bawah LSApplicationQueriesSchemes

<string>instagram</string>

- (void) shareImageWithInstagram
{
    NSURL *instagramURL = [NSURL URLWithString:@"instagram://"];
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
    {
        UICachedFileMgr* mgr = _gCachedManger;
        UIImage* photoImage = [mgr imageWithUrl:_imageView.image];
        NSData* imageData = UIImagePNGRepresentation(photoImage);
        NSString* captionString = [NSString  stringWithFormat:@"ANY_TAG",];
        NSString* imagePath = [UIUtils documentDirectoryWithSubpath:@"image.igo"];
        [imageData writeToFile:imagePath atomically:NO];
        NSURL* fileURL = [NSURL fileURLWithPath:[NSString stringWithFormat:@"file://%@",imagePath]];

        self.docFile = [[self setupControllerWithURL:fileURL usingDelegate:self]retain];
        self.docFile.annotation = [NSDictionary dictionaryWithObject: captionString
                                                     forKey:@"InstagramCaption"];
        self.docFile.UTI = @"com.instagram.photo";

        // OPEN THE HOOK
        [self.docFile presentOpenInMenuFromRect:self.view.frame inView:self.view animated:YES];
    }
    else
    {
        [UIUtils messageAlert:@"Instagram not installed in this device!\nTo share image please install instagram." title:nil delegate:nil];
    }
}

Saya mencoba ini di aplikasi saya dan itu pasti akan berhasil

Bagi saya, cara terbaik dan termudah dijelaskan di sini Bagikan foto ke Instagram dari Aplikasi iOS saya

Anda perlu menyimpan gambar di perangkat menggunakan format .igo, lalu gunakan "UIDocumentInteractionController" untuk mengirim aplikasi Instagram jalur lokal. Jangan lupa untuk menyetel "UIDocumentInteractionControllerDelegate"

Saran saya adalah menambahkan sesuatu seperti:

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) 
{
 <your code>
}

NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"];

if ([[UIApplication sharedApplication] canOpenURL:instagramURL])
{

    NSString  *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"Documents/Insta_Images/%@",@"shareImage.png"]];


    NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", jpgPath]];


    docController.UTI = @"com.instagram.photo";

    docController = [self setupControllerWithURL:igImageHookFile usingDelegate:self];

    docController =[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile];

    docController.delegate=self;

    [docController presentOpenInMenuFromRect:CGRectMake(0 ,0 , 612, 612) inView:self.view animated:YES];

Saya perhatikan jika Anda meletakkan URLmenunjuk ke gambar activityItemsalih-alih UIImage, Copy to Instagramitem aktivitas muncul dengan sendirinya, dan Anda tidak perlu melakukan apa pun. Harap dicatat bahwa Stringobjek di dalamnya activityItemsakan dibuang dan tidak ada cara untuk mengisi teks di Instagram. Jika Anda masih ingin memberi petunjuk kepada pengguna untuk memposting teks tertentu, Anda perlu membuat aktivitas khusus di mana Anda menyalin teks itu ke papan klip dan memberi tahu pengguna tentangnya, seperti dalam inti ini .

    @import Photos;

    -(void)shareOnInstagram:(UIImage*)imageInstagram {

        [self authorizePHAssest:imageInstagram];
    }

    -(void)authorizePHAssest:(UIImage *)aImage{

        PHAuthorizationStatus status = [PHPhotoLibrary authorizationStatus];

        if (status == PHAuthorizationStatusAuthorized) {
            // Access has been granted.
            [self savePostsPhotoBeforeSharing:aImage];
        }

        else if (status == PHAuthorizationStatusDenied) {
            // Access has been denied.
        }

        else if (status == PHAuthorizationStatusNotDetermined) {

            // Access has not been determined.
            [PHPhotoLibrary requestAuthorization:^(PHAuthorizationStatus status) {
