Question

我希望在UITextView中禁用双击。我已经禁用长按：

- (void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer {
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) {
        gestureRecognizer.enabled = NO;
    }
    [super addGestureRecognizer:gestureRecognizer];
    return;
}

我尝试用UITapGestureRecognizer做同样的事情，但它也禁止单击。

- (void)addGestureRecognizer:(UIGestureRecognizer *)gestureRecognizer {
    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]]) {
        gestureRecognizer.enabled = NO;
    }
    if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
        gestureRecognizer.enabled = NO;
    }
    [super addGestureRecognizer:gestureRecognizer];
    return;
}

如何只禁用双击？

我知道numberOfTapsRequired方法，但不知道如何在我的代码中完全应用它。

Answer 1

我建议您尝试使用

，而不是禁用点击手势识别器

if ([gestureRecognizer isKindOfClass:[UITapGestureRecognizer class]]) {
    [(UITapGestureRecognizer *)gestureRecognizer setNumberOfTapsRequired:1];
}

通过这种方式，您应该启用单击并禁用双击。

Answer 2

numberOfTapsRequired的默认值为1，将其设置为2.
