viewDidAppear not getting called

ios, ipad, iphone, objective-c

Solution

Presenting view controllers using presentModalViewController or segues or pushViewController should fix it.

Alternatively, if for some reason you want to present your views without the built-in methods, in your own code you should be calling these methods manually. Something like this:

[self addChildViewController:controller];
BOOL animated = NO;
[controller viewWillAppear:animated];
[self.view insertSubview:controller.view atIndex:0];
[controller viewDidAppear:animated];
[controller didMoveToParentViewController:self];

Problem

In my main UIViewController I am adding a homescreen view controller as subviews: ``` UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:vc]; controller.navigationBarHidden = YES; controller.view.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height); [self addChildViewController:controller]; [self.view insertSubview:controller.view atIndex:0]; [controller didMoveToParentViewController:self]; ``` The issue is that viewDidAppear and viewWillAppear is only called once, just like viewDidLoad. Why is this? How do I make this work? Basically inside vc I am not getting viewDidAppear nor viewWillAppear. I also just tried adding the UIViewController without the navigation controller and it still doesn't work: ``` vc.view.frame = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height); [self addChildViewController:vc]; [self.view insertSubview:vc.view atIndex:0]; [vc didMoveToParentViewController:self]; ```
