Saat ini saya mendapatkan layar kosong dengan Xcode 11, Target iOS 13.0 (aplikasi berfungsi baik dengan semua versi di bawah iOS 12.1 hingga 12.4), saya ingin membuat Aplikasi saya berfungsi untuk kedua pengguna iOS di atas 12.1 dan juga 13.0 saat ini mendapatkan layar kosong meskipun menambahkan SceneDelegate di bawah ini ke proyek saya yang ada dan
menambahkan file App Manifest
import UIKit
import SwiftUI
@available(iOS 13.0, *)
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
//guard let _ = (scene as? UIWindowScene) else { return }
let user = UserDefaults.standard.object(forKey: "defaultsuserid")
let userSelfIdent = UserDefaults.standard.object(forKey: "userinitialident")
if let windowScene = scene as? UIWindowScene {
let internalWindow = UIWindow(windowScene: windowScene)
if (user != nil && userSelfIdent != nil){
let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewcontroller:UIViewController = mainstoryboard.instantiateViewController(withIdentifier: "swrevealviewcontroller") as! SWRevealViewController
internalWindow.rootViewController = newViewcontroller
self.window = internalWindow
internalWindow.makeKeyAndVisible()
}else {
guard let _ = (scene as? UIWindowScene) else { return }
}
}
}
Berikut ini adalah AppDelegate saya yang dipanggil pertama dan menjalankan didFinishLaunchWithOptions
metode. Saya ingin tahu bagaimana saya bisa membuat metode ini hanya memanggil jika Target ios saya kurang dari 13.0 dan memanggil metode SceneDelegate untuk menginisialisasi rootViewController saya setelah 13.0?
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
@available(iOS 13.0, *)
func application(_ application: UIApplication,
configurationForConnecting connectingSceneSession: UISceneSession,
options: UIScene.ConnectionOptions) -> UISceneConfiguration {
return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role)
}
@available(iOS 13.0, *)
func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) {
}
@available(iOS 13.0, *)
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
guard let _ = (scene as? UIWindowScene) else { return }
if (user != nil && userSelfIdent != nil){
let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewcontroller:UIViewController = mainstoryboard.instantiateViewController(withIdentifier: "swrevealviewcontroller") as! SWRevealViewController
self.window?.rootViewController = newViewcontroller
}
}
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
Thread.sleep(forTimeInterval: 3.0)
UINavigationBar.appearance().barTintColor = UIColor(red:0.08, green:0.23, blue:0.62, alpha:1.0)
if (user != nil && userSelfIdent != nil){
let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewcontroller:UIViewController = mainstoryboard.instantiateViewController(withIdentifier: "swrevealviewcontroller") as! SWRevealViewController
self.window?.rootViewController = newViewcontroller
}
return true
}
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let defaultUserID = UserDefaults.standard.string(forKey: "defaultUserID")
}
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
switch (application.applicationState) {
case UIApplicationState.active:
do something
case UIApplicationState.background, UIApplicationState.inactive:
let mainstoryboard:UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let newViewcontroller = mainstoryboard.instantiateViewController(withIdentifier: "swrevealviewcontroller") as! SWRevealViewController
self.window?.rootViewController = newViewcontroller
}
