Instagram InstagramCaption无效

我有以下代码在Instagram上分享文章。

-(void) shareInstagram { NSURL *instagramURL = [NSURL URLWithString:@"instagram://app"]; if([[UIApplication sharedApplication] canOpenURL:instagramURL]) //check for App is install or not { UIImage *instaImage = mImg.image; NSData *imageData = UIImagePNGRepresentation(instaImage); //convert image into .png format. NSLog(@"imageData.leeee===%d", imageData.length); if (imageData.length<=100) { [self.view makeToast:localize(@"instaErr2") duration:2.0 position:@"bottom"]; } else { 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 *jpgPath = [NSHomeDirectory() stringByAppendingPathComponent:fileNameToSave]; NSLog(@"jpg path %@",jpgPath); NSString *newJpgPath = [NSString stringWithFormat:@"file://%@",jpgPath]; NSLog(@"with File path %@",newJpgPath); NSURL *igImageHookFile = [[NSURL alloc]initFileURLWithPath:newJpgPath]; NSLog(@"url Path %@",igImageHookFile); self.documentController.UTI = @"com.instagram.exclusivegram"; self.documentController = [self setupControllerWithURL:igImageHookFile usingDelegate:self]; self.documentController=[UIDocumentInteractionController interactionControllerWithURL:igImageHookFile]; NSString *globalString; if ([[[NSUserDefaults standardUserDefaults] valueForKey:@"PoPinFrom"] isEqualToString:@"user"]) { globalString = [NSString stringWithFormat:@"%@ @ %@\n\nhttp://egkw.com/ArticleDetail.aspx?id=%@\n\niPhone : %@\n\nAndroid : %@", [[productDetailsArray objectAtIndex:0] valueForKey:@"Title"], localize(@"appName"), [[productDetailsArray objectAtIndex:0] valueForKey:@"Id"], localize(@"appStoreLink"), localize(@"playStoreLink")]; } else { globalString = [NSString stringWithFormat:@"%@ @ %@\n\nhttp://egkw.com/ArticleDetail.aspx?id=%@\n\niPhone : %@\n\nAndroid : %@", [[productDetailsArray objectAtIndex:0] valueForKey:@"Title"], localize(@"appName"), [[productDetailsArray objectAtIndex:0] valueForKey:@"Id"], localize(@"appStoreLink"), localize(@"playStoreLink")]; } globalString = [NSString stringWithFormat:@"%@\n\n#EGKW", globalString]; NSLog(@"insta==globalString==%@", globalString); self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:globalString, @"InstagramCaption", nil]; // self.documentController.annotation = [NSDictionary dictionaryWithObject:globalString forKey:@"InstagramCaption"]; [self.documentController presentOpenInMenuFromRect:rect inView: self.view animated:YES]; } } else { NSLog (@"Instagram not found"); DTAlertView *myAl = [DTAlertView alertViewWithTitle:localize(@"err001") message:localize(@"instaErr") delegate:nil cancelButtonTitle:localize(@"dismiss") positiveButtonTitle:nil]; [myAl setDismissAnimationWhenButtonClicked:DTAlertViewAnimationSlideTop]; [myAl showWithAnimation:DTAlertViewAnimationSlideBottom]; } } 

这段代码工作得很好。 然而,当我注意到,我发现Instagram中没有显示标题。 研究后我改变了

  self.documentController.annotation=[NSDictionary dictionaryWithObjectsAndKeys:globalString, @"InstagramCaption", nil]; 

 self.documentController.annotation = [NSDictionary dictionaryWithObject:globalString forKey:@"InstagramCaption"]; 

但它仍然没有用。

什么是错的?

Instagram是否改变了像Facebook这样的政策?

Instagram现在使用交互控制器删除了标题字段的填写。
