Bagaimana cara menyimpan nilai CGRect di NSMutableArray?

Bagaimana cara menyimpan objek CGRect di NSMutableArray, dan kemudian mengambilnya kembali?

Anda perlu membungkus struktur CG di NSValuekelas. Begitu:

NSMutableArray* array = [NSMutableArray mutableArray];
[array addObject:[NSValue valueWithCGRect:CGRectMake(0,0,10,10)]];
CGRect someRect = [[array objectAtIndex:0] CGRectValue];

CGRect rect = CGRectMake( 5, 5, 40, 30 );
NSString* rectAsString = NSStringFromCGRect( rect );
CGRect original = CGRectFromString( rectAsString );

Apa pendapat Anda tentang cara menyimpan tanggal CGRect ini?

Kami menyimpan CGRect, CGPoint, CMTimeobjek dalam NSMutableArray,

[arrayName addObject:[NSValue valueWithCGPoint:MyCGPoint]]

[arrayName addObject:[NSValue valueWithCGRect:MyCGRect]]

[arrayName addObject:[NSValue valueWithCMTime:MyCMTime]]

[arrayName addObject:[NSValue valueWithCMTimeRange:MyCMTimeRange]]

Store string in array.and then get back string and convert that in CGRect back as per the need.
CGRect rect = CGRectMake( 5, 5, 40, 30 );
NSString* rectAsString = NSStringFromCGRect( rect );
NSMutableArray* array = [NSMutableArray mutableArray];
[array addObject:rectAsString];

For converting string in CGRect back use:-
CGRect rect9 = CGRectFromString(rectAsString);
