objective-c - 在 UITextView 中禁用双击

Question

我想在 UITextView 中禁用双击。我已经禁用了长按:

- (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;
}

如何禁用仅双击？

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

我建议您试试这个，而不是禁用您的点击手势识别器

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。
