title: Make AppDelegate's Navigation Controller accessible from DetailViewController of SplitView
body: <p>My DetailView of a SplitView has a Map with Annotations. Upon clicking an Annotation the entire window (and not just the DetailView) should go to another view. Unfortunately that doesn't work.</p>
  
  <p>This is how I'm creating my NavigationController in my AppDelegate</p>
  
  <pre><code> UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:self.viewController];  
  [self.window addSubview:navigationController.view];
  </code></pre>
  
  <p>This is how I'm creating the SplitView</p>
  
  <pre><code>left = [[MapSplitViewLeft alloc] initWithStyle:UITableViewStylePlain];
  right = [[MapViewController alloc] init];
  
  splitViewController = [[UISplitViewController alloc] init];
  splitViewController.viewControllers = [NSArray arrayWithObjects:left,right, nil];
  
  self.view = splitViewController.view;
  
  left.right = right;
  
  [left release];
  [right release];
  </code></pre>
  
  <p>And that's what's being called when clicked on an Annotation:</p>
  
  <pre><code>- (void)showDetails:(id)sender {
  
   NSLog(@"Yes it works");
  
   VenueViewController *vviewcontroller = [[VenueViewController alloc]
   initWithNibName:@"VenueViewController" bundle:[NSBundle mainBundle]];
  
   AppDelegate *del = (AppDelegate *)[UIApplication sharedApplication].delegate;
   [del.navigationController pushViewController:vviewcontroller animated:YES];
  
  }
  </code></pre>
  
  <p>When I click on the Annotation I only get "Yes it works" but nothing else is happening.
  Thanks so much for any advise.</p>
