如何在Swift中的touchedMoved期间检测新视图？

Question

我想在我的手指将aView移到bView的touchesMoved期间检测到新视图。我使用touchs.first进行检测，但是即使我的手指触摸（按入）bView也会显示aView。
如何检测我在touchedMoved中触摸（推动）哪个视图？

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first!
    print(touch.view) // return aView
}

override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
    let touch = touches.first!
    print(touch.view) // return aView even I'm touching bView from aView during this method
}

如果您的aView和bView是同一superview的后代，并且它们的框架不相交，则可以使用以下代码：

let touchLocation = touch.location(in: superview)
if aView.frame.contains(touchLocation) {
    // touch in aView
} else if bView.frame.contains(touchLocation) {
    // touch in bView
}
