why are my gestures not being reconized when i enter my app via URL Shortcut (open pdf in my app)?

Question

I have a gesture on a UITableView set up like so

//tableView:cellForRowAtIndexPath:
UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];
[cell addGestureRecognizer:lpgr];

in my app delegate, I'm handling shortcuts like so

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
if (url == nil) {
    NSLog(@"Shortcut: None");
    return NO;
}
NSLog(@"Shortcut: %@", [url absoluteString]);

    NSURLComponents *urlC = [[NSURLComponents alloc] initWithURL:url resolvingAgainstBaseURL:NO];
    if ([urlC.scheme isEqualToString:@"file"]) { //file:///private/var/mobile/...../Documents/Inbox/file.pdf

        FSCategoriesTVC *FSCategoriesTVC = [_window.rootViewController.storyboard instantiateViewControllerWithIdentifier:@"FSCategoriesTVC"];
        FSCategoriesTVC.isUploadingFile = YES;
        FSCategoriesTVC.fileToUpload = url;
        FSCategoriesTVC.navigationItem.prompt = @"Select project to add files to";

        UINavigationController *navController = [[UINavigationController alloc] init];
        [navController setViewControllers:@[FSCategoriesTVC] animated:NO];

        if(_window.rootViewController.presentedViewController != nil) {
            [_window.rootViewController dismissViewControllerAnimated:NO completion:^{ }];
        }
        [_window.rootViewController presentViewController:navController animated:NO completion:^{}];
        return YES;
    }
return NO;
}

what I'm doing is opening .pdf files in my app and uploading them to S3 to look at later. however, when the app launches this way, my gestures aren't recognized

e: i replace the gesture with a framework called BAMContextualMenu, hoping that would solve my problem, nope. same problem, the gesture aren't recognized when launching from shortcut

1. Try the view debugger to see if your view hierarchy is different when opened with a URL
2. Try handling the URL in application:willFinishLaunchingWithOptions: instead, because application:openURL:sourceApplication:annotation: is deprecated. You can retrieve the URL from the options dictionary using the UIApplicationLaunchOptionsURLKey key. That way you'll be initializing your view hierarchy with the same code whether or not there is a URL, which in my experience can be more foolproof. You can also implement application:openURL:options:.
