Answer 1

Another option :

use UIActivityViewController as available from iOS 6.0 > version

//create instance with file URL
UIActivityViewController *activity = [[UIActivityViewController alloc] initWithActivityItems:@[fileURLHere] applicationActivities:nil];
//present it
[self presentViewController:activity animated:YES completion:NULL];

Note : There might be problem using UIDocumentInteractionController. Check uidocumentinteractioncontroller-stopped-working-ios-8

Look at UIDocumentInteractionController https://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIDocumentInteractionController_class/Reference/Reference.html and here https://developer.apple.com/library/ios/#documentation/FileManagement/Conceptual/DocumentInteraction_TopicsForIOS/Articles/OpeningSupportedFileTypes.html#//apple_ref/doc/uid/TP40010412-SW1

Answer 3

UIDocumentInteractionController *controller = [UIDocumentInteractionController interactionControllerWithURL:[NSURL fileURLWithPath:appFile]];
        self.controller.delegate = self;
CGRect navRect = self.view.frame;
[self.controller presentOptionsMenuFromRect:navRect inView:self.view animated:YES];

Implement following UIDocumentInteractionControllerDelegate methods

#pragma mark - UIDocumentInteractionControllerDelegate

//===================================================================
- (UIViewController *)documentInteractionControllerViewControllerForPreview:(UIDocumentInteractionController *)controller
{
    return self;
}

- (UIView *)documentInteractionControllerViewForPreview:(UIDocumentInteractionController *)controller
{
    return self.view;
}

- (CGRect)documentInteractionControllerRectForPreview:(UIDocumentInteractionController *)controller
{
    return self.view.frame;
}
