Answer 1

In the UIDocumentInteractionController , there are two methods:

presentOpenInMenuFromBarButtonItem and presentOpenInMenuFromRect

Quite simple to use, first create and initialize an instance of UIDocumentInteractionController :

self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:yourFilePathURL];

Next present the open-in dialog using either one of the above mentioned methods.
