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)
}
