UIWindow 从中删除子视图后停止接收触摸
我使用 UIWindow 的子类来处理应用程序所有视图中的触摸事件。 我正在尝试实现拖放机制。
当点击并按住视图时，我会删除该视图并开始用手指拖动。 问题是在我删除视图后，窗口停止接收触摸事件，直到我抬起手指并再次触摸它。
帮助？
编辑： 我发现子视图被删除后，窗口正在接收触摸，但触摸阶段是 UITouchPhaseStationary 而不是 UITouchPhaseMoved，即使 [event Touchs] 中只有一个 UITouch；这怎么可能？
I'm using a subclass of UIWindow to handle touch event in all views of the app.
I'm trying to implement a drag and drop mechanism.
When tapping and holding on a view, i remove that view and start dragging with the finger.
problem is after i remove the view the window stop receiving touch events until i lift my finger and touch it again.
help?
EDIT:
i found that after the subview is removed, the window is receiving touches but the touch phase is UITouchPhaseStationary and not UITouchPhaseMoved, even though there is only one UITouch in [event touches]; how is this possible?

我不太确定，但我认为你的问题是因为你试图处理
UIWindow类中的事件，而不是UIViewController类。 UIWindow 的设计初衷并不是这样做。为什么不试试这个：UIViewController类的实例添加到您的项目中。UIViewController的视图添加到您的UIWindow实例中。UIViewController。UIViewController。（这是在
UIViewController下交换视图，而不是在UIWindow实例中交换视图。）I am not quite sure, but I think your problem is because your are trying to handle events in
UIWindowclass, rather thanUIViewControllerclass. UIWindow is not designed to do so. Why don't you try this:UIViewControllerclass to your project.UIViewControllerto yourUIWindowinstance.UIViewController.UIViewController.UIViewController, and bring in the second view, or whatever.(It is kind of swapping views under the
UIViewController, rather than in the instance ofUIWindow.)
