Loading a ViewController inside a Container View

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.

Tried to use the answer above but it turns out CGRectMake isn't available anymore.

Updated for Swift 3:

self.addChildViewController(vc)
vc.view.frame = CGRect(x: 0, y: 0, width: self.container.frame.size.width, height: self.container.frame.size.height)
self.container.addSubview(vc.view)
vc.didMoveToParentViewController(self)
