與Instagram的

您好我需要導入Instagram的我編輯的圖像開放的形象，像PhotoStudio中：與Instagram的

enter image description here

我俘獲了我的這個代碼映像：

UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0); 
    [self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()]; 
    UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext(); 

    UIGraphicsEndImageContext();

然後，我需要用Instagram打開screenShot：

EDITED：

我實現這樣的方法：

UIGraphicsBeginImageContextWithOptions(self.captureView.bounds.size, self.captureView.opaque, 0.0); 
    [self.captureView.layer renderInContext:UIGraphicsGetCurrentContext()]; 
    UIImage * screenshot = UIGraphicsGetImageFromCurrentImageContext(); 
    UIGraphicsEndImageContext(); 
    NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", screenshot]]; 

    docFile.UTI = @"com.instagram.photo"; 
    [self setupDocumentControllerWithURL:igImageHookFile]; 

    NSURL *instagramURL = [NSURL URLWithString:@"instagram://media?id=MEDIA_ID"]; 
    if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) { 
     [[UIApplication sharedApplication] openURL:instagramURL]; 
    } 

    else { 
     NSLog(@"No Instagram Found"); 
    } 
}

但我收到此輸出：

2012-05-05 21:55:36.842 InstantFrame[855:707] *** Assertion failure in -[UIDocumentInteractionController setURL:], /SourceCache/UIKit/UIKit-1914.84/UIDocumentInteractionController.m:1094 
2012-05-05 21:55:36.848 InstantFrame[855:707] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UIDocumentInteractionController: invalid scheme (null). Only the file scheme is supported.'

的Instagram將被打開，但不輸入任何東西。

你做了Instagram的？ PLZ與我分享Instagram的部分 – Hiren
