Loading a ViewController inside a Container View

Question

I have a containerView with full screen inside a VC. If i add a child to the containerView manually from a Storyboard doing a embed segue looks fine:

You need to tell your BannerContainer view controller that it has a new child controller, and to tell the Child that it has a parent VC. This is described in the Apple Docs here. Like this:

   [self addChildViewController:vc];
   vc.view.frame = CGRectMake(0, 0, self.container.frame.size.width, self.container.frame.size.height);
   [self.container addSubview:vc.view];
   [vc didMoveToParentViewController:self];

Or in Swift:

    self.addChildViewController(vc)
    vc.view.frame = CGRectMake(0, 0, self.container.frame.size.width, self.container.frame.size.height);
    self.container.addSubview(vc.view)
    vc.didMoveToParentViewController(self)

This ensures that various layout and touch methods are passed through to the child VC; I suspect the layout problems you have may be due to those methods not currently being called.
