Question

I have a view controller with a content view, where I am trying to assign a child view controller to that content view. My code works fine for iOS 6.0, but throws sigabrt for 5.0/5.1. Here’s the relevant code:

- (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  ContentWebViewController *initialContentVC = [[ContentWebViewController alloc] init];
  [self addChildViewController:initialContentVC];
  [initialContentVC.view setFrame:self.view.bounds];  // Throws SIGABRT here
  [self.containerView addSubview:initialContentVC.view];
  [initialContentVC didMoveToParentViewController:self];
  self.currentContentVC = initialContentVC;
}

What’s going on here???

Answer 1

Xcode automatically checked “Use AutoLayout” in my nib file in IB. That’s why crashing on iOS earlier than 6.0. Unchecking it did the trick. This got me a few weeks ago too, how annoying!
