ios - 您可以将 UIGestureRecognizer 附加到多个 View 吗？

Question

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)];
[self.view1 addGestureRecognizer:tapGesture];
[self.view2 addGestureRecognizer:tapGesture];
[tapGesture release];

在上面的代码中，只有对 view2 的点击被识别。如果我注释掉第三行，则可以识别对 view1 的点击。如果我是对的并且您只能使用一次手势识别器，我不确定这是一个错误还是它只需要更多文档。

Answer 1

UIGestureRecognizer 将与单个 View 一起使用。我同意文档参差不齐。那 UIGestureRecognizer 有一个单一的 view 属性给它了:

view

The view the gesture recognizer is attached to. (read-only)

@property(nonatomic, readonly) UIView *view

Discussion You attach (or add) a gesture recognizer to a UIView objectusing the addGestureRecognizer:method.
