[iphone] iPhone - Get Position of UIView within entire UIWindow

The position of a UIView can obviously be determined by view.center or view.frame etc. but this only returns the position of the UIView in relation to it's immediate superview.

I need to determine the position of the UIView in the entire 320x480 co-ordinate system. For example, if the UIView is in a UITableViewCell it's position within the window could change dramatically irregardless of the superview.

Any ideas if and how this is possible?

Cheers :)

Swift 5+:

let globalPoint = aView.superview?.convert(aView.frame.origin, to: nil)

Swift 3, with extension:

extension UIView{
    var globalPoint :CGPoint? {
        return self.superview?.convert(self.frame.origin, to: nil)
    }

    var globalFrame :CGRect? {
        return self.superview?.convert(self.frame, to: nil)
    }
}

In Swift:

let globalPoint = aView.superview?.convertPoint(aView.frame.origin, toView: nil)

Here is a combination of the answer by @Mohsenasm and a comment from @Ghigo adopted to Swift

extension UIView {
    var globalFrame: CGRect? {
        let rootView = UIApplication.shared.keyWindow?.rootViewController?.view
        return self.superview?.convert(self.frame, to: rootView)
    }
}

For me this code worked best:

private func getCoordinate(_ view: UIView) -> CGPoint {
    var x = view.frame.origin.x
    var y = view.frame.origin.y
    var oldView = view

    while let superView = oldView.superview {
        x += superView.frame.origin.x
        y += superView.frame.origin.y
        if superView.next is UIViewController {
            break //superView is the rootView of a UIViewController
        }
        oldView = superView
    }

    return CGPoint(x: x, y: y)
}
