title: Simulate Launch Options
body: <p>in my <code>appDelegate</code>, I have some specifications when the App is launch with a File from  i.e. Mail app.</p>
  
  <p>When I launch my App, everything works normal. When I launch the App via File from Mail, the App crashes. Unfortunately, I am not able to debug it as I can't simulate <code>launchingOptions</code>. at the moment, I build and run, then disconnect the iPad, close my App and then go to mail etc … Is there a way to debug?</p>
  
  <p><strong>Appdelegate.m</strong></p>
  
  <pre><code> - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
  
  NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
  
  IntroViewController *introViewController = (IntroViewController *)self.window.rootViewController;
  
  if (url !=nil) {
      if ([url isFileURL]) {
          introViewController.fileUrl = url;
      }
  
  
  }
  
  NSLog(@"%@",[url path]);
  
  return YES;
  }
  </code></pre>
  
  <p><strong>IntroViewController</strong></p>
  
  <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

      NSLog(@"Hello");
      if (fileUrl != nil) {
          IntroTableViewController* introTable = (IntroTableViewController *)segue.destinationViewController;            
          introTable.openedByURL = [fileUrl path];
  
          TabBarController* tabBarController = (TabBarController *)segue.destinationViewController;
          UINavigationController* navigationController = (UINavigationController *)[[tabBarController viewControllers] objectAtIndex:0];

          NSString *urlPath = [fileUrl path];
