title: CGPoint Local To Global Issue
body: <p>I am stuck at a Local to Global Point issue in Objective C ViewController base Application</p>
  
  <p>I have one ScrollView as a SubView of the ViewController which has Around 13 to 15 UIButtons as a SubView at a Time there are only 3 UIButton which are in the View of the ScrollView. </p>
  
  <p>What i want is to get the CGPoint(Global) of the UIButton which is a subView of ScrollView but not the local CGpoint inside the ScrollView. </p>
  
  <p>Is there a way to get the Local CGPoint to be Converted to Global CGPoint. </p>
  
  <p>Thanks Guyz
