title: UIView absolute screen point
body: <p>Is there an easy way of getting the absolute point of UIView? By absolute I mean the location of the UIView relative to 1024x768 on an iPad?</p>
  
  <p>I need an easy way because I have a UIButton inside a UITableViewCell inside a UITableView inside a view presented by a viewcontroller that is a child of another view controller repeating to the fifth or sixth view controller.
  And due to this complex design I need the absolute rect of the UIButton so I can display an UIActionSheet on the "main" viewcontroller.</p>
