以自定义方式从 UIApplication 传播触摸
是否可以将触摸从共享应用程序对象传播到尚未实际接收触摸且位于顶视图后面某处的自定义视图？ 假设我无法使用顶视图来跟踪触摸。
Is it possible to propagate touches from shared application object to a custom view which has not actually received touches and somewhere at the back of the top view? Assume that I can't use my top view to track touches.

这会很困难 - 因为顶视图首先接收事件。
你不能只在顶层视图上调用 userInterActionEnabled ，然后将事件传递到较低层吗？
It would be difficult - because the top view receives the event first.
You can't just call userInterActionEnabled on the top view, and pass the event down to a lower layer?
