Great – I should certainly pronounce, impressed with your website. I had no trouble navigating through all tabs as well as related info ended up being truly simple to do to access. I recently found what I hoped for before you know it in the least. Reasonably unusual. Is likely to appreciate it for those who add forums or something, web site theme . a tones way for your customer to communicate. Nice task.

hi All! You can trie that

(void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; UINavigationController *navController =[self.tabBarController.viewControllers objectAtIndex:appDelegate.indexOfTab]; [navController viewWillAppear:animated]; NSLog(@"viewWillAppear:(BOOL)animated"); }

-(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; UINavigationController *navController =[self.tabBarController.viewControllers objectAtIndex:appDelegate.indexOfTab]; [navController viewDidAppear:animated]; //[self.navigationController viewDidAppear:animated]; NSLog(@"viewDidAppear:(BOOL)animated"); } -(void)viewDidDisappear:(BOOL)animated { [super viewDidDisappear:animated]; [self.navigationController viewDidDisappear:animated]; NSLog(@"viewDidDisappear:(BOOL)animated"); }

After trying all the various solutions described here, with various degree of success, I found a 1-LINE-SOLUTION in another thread online:

[parentViewController.view addSubview:[subViewController view]]; [subViewController viewWillAppear:NO]; // <-- ONE LINE fix

That's it. After I added that line, all the viewWillAppear, viewWillDisappear, viewDidAppear and viewDidDisappear get propagated through navigation, tabBar and children views.
