Answer

Try using this line in your .h file:

@property (strong, nonatomic) UIDocumentInteractionController *documentInteractionController;

And these to your .m file:

self.documentInteractionController= [UIDocumentInteractionController interactionControllerWithURL:url];
//set delegate
[self.documentInteractionController setDelegate:self];
//provide button's frame from where popover will be lauched

[self.documentInteractionController presentOpenInMenuFromRect:CGRectZero inView:self.view animated:YES];
