title: What is the difference between view controller life cycle and view life cycle in iOS?
body: <p>Reading several tutorials and books on iOS development I often encounter terms : <code>UIViewController</code> life cycle and <code>UIView</code> life cycle. I'm interested: is there an <em>actual</em> difference between these two terms?
  Looking Apple docs I found that methods such as <code>viewDidAppear</code> or <code>loadView</code> is a part of view controller's life cycle, but I think it is more correct to refer them as view life cycle and methods such as <code>initWithNibName</code> or <code>dealloc</code> as controller's life cycle. Or there is no such a separation and when someone speaks about view life cycle he actually means <code>UIViewController</code> life cycle?</p>
