fileURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:documents[cellIndexPath.row] ofType:nil]];

fileURL = [self.documentURLs objectAtIndex:cellIndexPath.row];
}
self.docInteractionController.URL = fileURL;
[self.docInteractionController presentOptionsMenuFromRect:longPressGesture.view.frame
inView:longPressGesture.view
animated:YES];
WHAT SHOULD I DO TO GET THE MAIL OPTION?

Answer 1

To provide the Mail option, -presentOpenInMenuFromBarButtonItem: needs to be -presentOptionsMenuFromRect:
As per the Apple Docs on UIDocumentInteractionController
For -presentOpenInMenuFromBarButtonItem:animated: it says:
This method is similar to the
presentOptionsMenuFromBarButtonItem:animated: method, but presents a
menu restricted to a list of apps capable of opening the current
document. This determination is made based on the document type (as
indicated by the UTI property) and on the document types supported by
the installed apps.
...
If there are no registered apps that support opening the document, the
document interaction controller does not display a menu.
So:
To present options to open the file, use -presentOpenInMenuFromBarButtonItem:
To present all possible options applicable on the file, use -presentOptionsMenuFromBarButtonItem: or the generic -presentOptionsMenuFromRect:
Also... for any file, it would be better to specify the UTI type:
Example:
docInteractionController = [UIDocumentInteractionController interactionControllerWithURL:fileURL];
//[docInteractionController setDelegate:self];
[docInteractionController setUTI:#"public.data"];
[docInteractionController presentOptionsMenuFromBarButtonItem:(UIBarButtonItem*)sender
animated:YES];
//or a generic method
//[docInteractionController presentOptionsMenuFromRect:sender.frame
// animated:YES];
