title: Get button position in view while button is in cell
body: <p>I have a table view that has custom cells. In every cell I have a button. When I click on any button I can get its frame but that frame is in the cell. I want button's position in the self.view is this possible? 
  I can get the relative position by getting cell's frame and table's start position but Is there any appropriate way to get any object's position in view?</p>
  
  <p>Thanks</p>
