Integration of Instagram in iPhone - iphone

Question

I am trying to post a photo to Instagram through my app. I am using UIDocumentInteractionController according to INstagram guidlines
in my .h file
UIDocumentInteractionController *documentInteractionController;
in my .m file
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:#"IMG_0192" ofType:#"jpg"];
fileToOpen = [fileToOpen substringToIndex:[fileToOpen length] - 3];
fileToOpen=[NSString stringWithFormat:#"%#ig",fileToOpen];
NSURL *instagramURL = [NSURL URLWithString:#"instagram://app"];
NSLog(#"%#",fileToOpen);
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]) {
//imageToUpload is a file path with .ig file extension
/*UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#""
message:#"Can open app!"
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
*/
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
self.documentInteractionController.UTI = #"com.instagram.photo";
self.documentInteractionController.annotation = [NSDictionary dictionaryWithObject:#"Its a testing" forKey:#"InstagramCaption"];
is am missing something.??it is not working.

Answer 1

I think your photo ID or file URL is not correct here. I've done this successfully with the following code snippet:
in your .h file:
#property (nonatomic, retain) UIDocumentInteractionController *docDic;
also add the following delegate:
UIDocumentInteractionControllerDelegate
in your .m file:
synthesize the docDic object
Write the following method:
-(UIDocumentInteractionController *)setupControllerWithURL:(NSURL*)fileURL usingDelegate:(id<UIDocumentInteractionControllerDelegate>)interactionDelegate{
UIDocumentInteractionController *interactionController = [UIDocumentInteractionController interactionControllerWithURL: fileURL];
interactionController.delegate = interactionDelegate;
return interactionController;
}
Then add the following code snippet to your shareToInstagram function:
NSString *fileToOpen = [[NSBundle mainBundle] pathForResource:#"IMG_0192" ofType:#"jpg"];
fileToOpen = [fileToOpen substringToIndex:[fileToOpen length] - 3];
fileToOpen=[NSString stringWithFormat:#"%#.ig",fileToOpen];
NSURL *instagramURL = [[NSURL alloc] initWithString:[[NSString alloc] initWithFormat:#"file://%#", fileToOpen]];
if ([[UIApplication sharedApplication] canOpenURL:instagramURL]){
self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:fileToOpen]];
self.documentInteractionController.UTI = #"com.instagram.photo";
[self.dic presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
}
Hopefully it will help you. Best of luck. :-)
