UIImageView的UITextField子视图不响应触摸事件(UITextField subview of UIImageView is not responding to touch even

UIImageView的UITextField子视图不响应触摸事件(UITextField subview of UIImageView is not responding to touch events)

当它作为self.view的子视图添加时，我有一个UITextField，用于响应触摸事件。 当我将它作为UIImageView的子视图添加时，它不再响应触摸事件。 我使它成为第一个响应者，并且该字段处于活动状态，并且仍然需要键盘输入。 任何想法有什么不对？

I have a UITextField that responds to touch events when it is added as a subview of self.view. When I add it as a subview of a UIImageView it does not respond to touch events any more. I make it a firstResponder and the field is active and takes keyboard input still. Any ideas what is wrong?

UIImageView状态的文档 ：

新的图像视图对象被配置为默认忽略用户事件。 如果要处理UIImageView的自定义子类中的事件，则必须在初始化对象后明确将userInteractionEnabled属性的值更改为YES。

尝试设置imgView.userInteractionEnabled = YES

如果这不起作用，我会尝试在UIView中添加UIImageView和UITextField。 无论如何，这种方法似乎更清洁。

The docs for UIImageView state:

New image view objects are configured to disregard user events by default. If you want to handle events in a custom subclass of UIImageView, you must explicitly change the value of the userInteractionEnabled property to YES after initializing the object.

Try setting imgView.userInteractionEnabled = YES

If this doesn't work, I would try adding the UIImageView and the UITextField in a UIView instead. Anyway, this approach seems cleaner.
