uitextview - 如何在 UITextView 上禁用 UITextTapRecognizer

Question

我想尝试禁用 UITextTapRecognizer，我认为它是 UITextView 的内置属性，因为我怀疑它会干扰我想要实现的点击手势识别器。这怎么可能？

我不确定这是否直接回答了您的问题(即“禁用 UITextTapRecognizer”)，但我认为它可能会有所帮助。您可以阻止 tapRecognizer 识别手势，从而基本上“禁用”它(我认为)。

"You can prevent gesture recognizers from looking at specific touches or from even recognizing a gesture. You can specify these “prevention” relationships using either delegation methods or overriding methods declared by the UIGestureRecognizer class.

The UIGestureRecognizerDelegate protocol declares two optional methods that prevent specific gesture recognizers from recognizing gestures on a case-by-case basis."

尝试 gestureRecognizerShouldBegin: 或 gestureRecognizer:shouldReceiveTouch: 委托(delegate)协议(protocol)方法。

"In addition, there are two UIGestureRecognizer methods (declared in UIGestureRecognizerSubclass.h) that effect the same behavior as these delegation methods. A subclass can override these methods to define class-wide prevention rules."

看:

- (BOOL)canPreventGestureRecognizer:(UIGestureRecognizer *)preventedGestureRecognizer;
- (BOOL)canBePreventedByGestureRecognizer:(UIGestureRecognizer *)preventingGestureRecognizer;
