CameraOverlayView 按钮
我正在将一个cameraOverlay添加到我的UIImagePickerController中，它显示了所有内容，但它没有注册触摸。我在 viewDidLoad 中初始化了一个按钮，并通过 IB 初始化了一个按钮。
是否有一些规则禁止我将 UIButton 添加到cameraOverlayView 并注册触摸？
谢谢
I'm adding a cameraOverlay to my UIImagePickerController, it shows and all but it doesn't register touches. I init a button in the viewDidLoad and a one via IB.
Is there some rule that prohibits me from adding a UIButton to a cameraOverlayView and register touches?
Thanks

我遇到了类似的问题，结果发现我的覆盖 UIView 的框架不够大。 UIView 的 ClipsToBounds 属性默认设置为 NO，这意味着即使子视图位于父级框架之外，它们仍然可见。
因此，本质上，请确保叠加层的框架足够大，或者叠加层的子视图位于其边界内。
I had a similar problem, and it turned out that my overlay UIView's frame was not large enough. The
clipsToBoundsproperty for a UIView is by default set to NO, which means its subviews are still visible even if they are outside the parent's frame.So essentially, make sure your overlay's frame is large enough, or that your subviews of the overlay are positioned within its bounds.
