Lifecycle for Views

Guidelines:

• Call init once and render many times
• Call init to do model loading and when done call render
• Call deinit when remove view and set controller to null
• When a view that is to be reused is hidden, it can
  • stop listening for model changes so that it doesn't render when not being shown, and then always render when going back to the view
  • or keep listening for model changes, but don't render, instead set a flag and then when going back to the view, if any model changes happened that it cares about, it can then render
