I'm a little confused how containers works. I have containers:

And i try to manage this in my MainViewController. But when i control-drag it into my .h file i'm getting
@property (weak, nonatomic) IBOutlet UIView *liveContainer;
Why this is an UIView class? This mean that is self.view my BaseButtonContainerView? But I have BaseButtonContainerViewController, and in debug i see that viewDidLoad is called. Can i get access to BaseButtonContainerViewController methods from MainViewController?
