Share text with Images on Instagram in ios

In my App I sharing an image on Instagram. It is working well in my app. I am using the following code. ``` @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]]; // NSURL *igImageHookFile = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:@"file://%@", screenshot]]; 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; } ``` Now I also want to share some text with the image. As shown in the Image below. In " Write a Caption", I want some default custom text for eg. "Share this photo". How can I do this? Thanks in advance... Edited I am opening Instagram from my app for sharing images and it works fine. But Is it possible that Can I check Whether the user has shared it successfully or not? Means I want to perform some action in my DB when user successfully shares an image. How can i do this?
