Martin answer is correct. For developers using Swift, you can get the position of an object (button, view,...) relative to the screen by using:

var p = obj.convertPoint(obj.center, toView: self.view)

println(p.x)  // this prints the x coordinate of 'obj' relative to the screen
println(p.y)  // this prints the y coordinate of 'obj' relative to the screen
