UITapGestureRecognizer 中的点击次数有问题

Question

我正在电视遥控器上尝试运行两次 tapping 一种方法，考虑点击 而不是 点击，但触摸表面不会认识水龙头。相反，单击运行两次 doubleTapping 方法。

UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    doubleTap.allowedTouchTypes =@[[NSNumber numberWithInteger:UITouchTypeIndirect]];
    doubleTap.numberOfTapsRequired = 2;
    [self.view addGestureRecognizer:doubleTap];



- (void)handleTap:(UITapGestureRecognizer *)sender
{
    if (sender.state == UIGestureRecognizerStateBegan)
    {
        // handling code
        NSLog(@"2 times");
    }
}

我错过了什么？

Answer 1

我忘了提到 UIPressType 值，现在由于遥控器表面的位置（上/下/右/左），您现在可以检测用户的点击方向并将 numberOfTapsRequired 添加到动作：

 UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)];
    [tapGestureRecognizer setAllowedPressTypes:@[@(UIPressTypeLeftArrow)]];
    [tapGestureRecognizer setNumberOfTapsRequired:2];
    [self.view addGestureRecognizer:tapGestureRecognizer];
