Combine UIDocumentInteractionController with UIActivityController to share on Instagram, Facebook, to mail, message and so on

Question

I need to be able to share photos on Instagram as well as also to all the options that are presented with UIActivityViewController - Facebook, Twitter, mail, etc. I manage to share to Instagram with UIDocumentInteractionController, but need to have all the options at one place. I added custom UIActivity to the UIActivityViewController activities, but don't know how to proceed directly to Instagram from there. Now it just options similar menu with the Instagram option, because I present a UIDocumentInteractionController. Is there a way to have all options at one menu?

Thanks to: Sharing image to Whatsapp & Facebook accepted response.

It looks that this option is actually provided out of the box for UIDocumentInteractionController, but I was presenting the controller wrongly. The correct way to display all options is to use: -presentOptionsMenuFromRect:inView:animated: instead of -presentOpenInMenuFromRect:inView:animated:
The UIDocumentInteractionController does not allow to omit some of the options like UIActivityViewControllerdoes, but I need to have Instagram alongside the other options, so this is the way to go. The code I use:

NSString *documentDirectory=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *saveImagePath=[documentDirectory stringByAppendingPathComponent:@"MyImage.png"];
NSData *imageData=UIImagePNGRepresentation(imageToUse);
[imageData writeToFile:saveImagePath atomically:YES];
NSURL *imageURL=[NSURL fileURLWithPath:saveImagePath];
docIntController = [UIDocumentInteractionController interactionControllerWithURL:imageURL];
docIntController.delegate = self;
[docIntController presentOptionsMenuFromRect:CGRectMake(1, 1, 1, 1) inView:self.view animated:YES];
