当父不是窗口时,有没有办法获得相对于最内层NSView的坐标？

let superview = view.superview

let index = superview.subviews.firstIndex(of: view)

let frame = view.frame
let origin = frame.origin

func getSuperviewOrigin(_ view: NSView) -> CGPoint {
    let superview = view.superview
    let index = superview.subviews.firstIndex(of: view)
    let frame = view.frame
    let origin = frame.origin
    if let superview = superview.superview {
        let superOrigin = getSuperviewOrigin(superview)
        return CGPoint(x: origin.x + superOrigin.x, y: origin.y + superOrigin.y)
    } else {
        return origin
    }
}
