Remarks
This method is invoked if the contents of the view need to be refreshed due to a change of state or geometry. Invoking this method will cause the Draw(CGRect) method to be invoked.
Alternatively you can use the SetNeedsDisplayInRect(CGRect) method to only mark a specific region of the view to be repainted.
