Get position of UIView in respect to its superview's superview

You can use this:

Objective-C

CGRect frame = [firstView convertRect:buttons.frame fromView:secondView];

Swift

let frame = firstView.convert(buttons.frame, from:secondView)

Documentation reference:

https://developer.apple.com/documentation/uikit/uiview/1622498-convert

Although not specific to the button in the hierarchy as asked I found this easier to visualize and understand:

From here: original source

ObjC:

CGPoint point = [subview1 convertPoint:subview2.frame.origin toView:viewController.view];

Swift:

let point = subview1.convert(subview2.frame.origin, to: viewControll.view)

Updated for Swift 3

    if let frame = yourViewName.superview?.convert(yourViewName.frame, to: nil) {

        print(frame)
    }
