title: popviewcontroller is not calling viewWillappear
body: <p>I'm using the following code to display the previous view when a user is clicking on a button</p>
  
  <pre><code>[self.navigationController popViewControllerAnimated:YES];
  </code></pre>
  
  <p>In the previous view,  I overwrite  viewWillAppear to initialized few things.  However, it seems like viewWillAppear is not being called.  I put NSLog in viewDidload, viewWillAppear, viewDidAppear and only viewDidAppear is being called.  Is this normal behavior?  If yes, what event should I override so I can do my initialization?  Thank you.</p>
  
  <p>As requested -viewWillAppear for the previous view</p>
  
  <pre><code>- (void)viewWillAppear:(BOOL)animated{
  
      NSLog(@"ViewWillAppear");
          //[[GameStore defaultStore] resetGame];
          [self setHangmanImage];
  
      NSLog([[[GameStore defaultStore] selectedList] label]);
          [labelListName setText:[NSString stringWithFormat:@"List Name: %@", [[[GameStore defaultStore] selectedList] label]]];
          [labelCurrentIndex setHidden:YES];
          [labelCurrentWord setHidden:YES];
          [[self navigationController] setNavigationBarHidden:NO];
  
          [FlurryAnalytics logEvent:@"GameViewController - viewWillAppear"];
  
          [self getNewQuestion];
  
      NSLog(@"ViewWillAppear finish");
      [super viewWillAppear:YES];
  
  }
  </code></pre>
  
  <p>I setup the UINavigationalController in the app delegate using the following code</p>
  
  <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
  {
      HomeViewController *hv = [[HomeViewController alloc] init];
  
      UINavigationController *navController = [[UINavigationController alloc]
                                               initWithRootViewController:hv];
  
      // You can now release the itemsViewController here,
      // UINavigationController will retain it
      [hv release];
  
      // Place navigation controller's view in the window hierarchy
      [[self window] setRootViewController:navController];
  
  
      [navController release];
  
  
      // Override point for customization after application launch.
      [self.window makeKeyAndVisible];
      return YES;
  }
  </code></pre>
  
  <p><strong>UPDATE</strong></p>
  
  <p>I don't know what happened but last night after trying to run the app one more time in the simulator and its still having this issue, I decided to save everything and shut my computer down since it was getting late.  </p>
  
  <p>This morning I turned my computer back on opened up xcode, clean the project and build and run it and I the problem is fixed and -viewWillAppear is called.  I didn't change anything and its working.  I added NSLog in -willShowView and its not getting called.  I don't know why all of a sudden viewWillAppear is being called.</p>
