问题：只要我直接在我的UIInputViewController[=]中使用BannerViewclass 35=] 手势被识别，没有问题。
只要我将此 class 移动到另一个自定义视图并在我的控制器中使用此自定义视图，手势和点击就会停止响应。
这是使用 BannerView 的第三个 class：

所以问题是：如何将自定义视图移动到另一个自定义视图，并且仍然只在具有手势识别器的自定义视图上获取滑动事件？
最终问题是添加到自定义视图 (KeysView) 的第二个视图占用了父自定义视图 (KeyboardView) 的所有 space，因此第二个视图自定义视图 (BannerView) 被第一个视图 (KeysView) 覆盖，它把所有的点击事件都交给自己，而不将它们传递给下一个视图。
我为解决这个问题所做的是：
1.更改KeyboardView（父视图）中两个自定义视图的初始化顺序。所以基本上首先我实例化较大的视图 (KeysView) 然后我实例化较小的视图 (BannerView)。
此外，我在 BannerView 中添加了以下方法：
override func pointInside(point: CGPoint, withEvent event: UIEvent?) -> Bool {
let contains: Bool = CGRectContainsPoint(self.frame, point)
if contains {
return true
} else {
return false
}
}
所以 BannerView（最顶层的视图）只处理自己的事件（事件点的检查包含在视图中）并将不为自己的事件传递到视图层次结构中。
