Ios 禁用UIScrollView将事件拖动到特定方向，并将事件发送到super

我有

ui视图

，并在其上附加了

ui测试识别器

。 在

UIView

中，我启用了

UIScrollView

，并设置了内容大小，这样滚动视图就可以滚动到左侧

问题：

---

我希望当用户尝试向右拖动scrollView时，将事件发送到UIView，以便“UIPangestureRecognitizer”能够处理触摸事件，最后，在6小时后，我找到了它 我将

UIScrollView

子类化，并实现了

gestureRecognizer:shouldRecognizeSimultaneouswithgestureRecognizer

委托方法

当用户拖动滚动视图时，此方法被称为

（BOOL）gestureRecognizer:shouldRecognizeSimultaneouswithGestureRecognizer

，默认情况下，它返回NO

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
    if (self.contentOffset.x > 0 &&  self.contentOffset.x <= self.contentSize.width - self.frame.size.width) {
        //user is in middle of dragging the scrollView don't allow any other gestureRecognizer to respond
        return NO;
    }else{
        //scrollView contentOffset is 0 and user is not dragging the scrollView so let other gestureRecognizer to respond
        return YES;
    }
}

-（BOOL）GestureRecognitor:（UIGestureRecognitor*）GestureRecognitor应与GestureRecognitor:（UIGestureRecognitor*）其他GestureRecognitor同时识别{
如果（self.contentOffset.x>0&&self.contentOffset.x在尝试使用Horam的答案时，我意识到
scrollView.PangestureRecognitor
在
返回NO
后被切断。我想要的是我的自定义平移识别器被切断，而scrollView仍在滚动。我想这可能是手势的结果我不确定在不同的级别添加了res

然而，我找到了一个解决方案，将我的自定义手势识别器更改为检查
scrollView.contentOffset
并在其大于零的情况下不激活。我还关闭了
scrollView.bounce
属性，直到
scrollView.contentOffset
为零。在我的scrollView上向下滚动时，它会点击最后，我的手势识别器会立即接管并将superview移到我想要的地方

这是我定制的平移姿势的骨架

- (void)customPan:(UIPanGestureRecognizer*)panRecognizer
{
    if(panRecognizer.state == UIGestureRecognizerStateBegan)
    {
        //do begin stuff
    }

    if(panRecognizer.state == UIGestureRecognizerStateChanged)
    {
        if(self.scrollView.contentOffset.y > 0)
        {
            //do begin stuff to make sure it’s initialized properly when it does start to change
            self.scrollView.bounces = YES;
            return;
        }
        else
        {
            self.scrollView.bounces = NO;
        }

        //do change stuff
    }

    if(panRecognizer.state == UIGestureRecognizerStateEnded)
    {
        if(self.scrollView.contentOffset.y > 0)
        {
            //do begin stuff to make sure it’s initialized properly when it does start to change
            self.scrollView.bounces = YES;
            return;
        }
        else
        {
            self.scrollView.bounces = NO;
        }

        //do end stuff

    }
}
