滑动手势会中断iOS 13中的UISlider控件，但不会中断以前的iOS版本 [英] Swipe gesture interrupts UISlider control in iOS 13, but not previous iOS versions

问题描述

注意:这是iOS 13 Beta，但也可能会在明天正式发布.

Note: This is the iOS 13 beta, but also could apply to the official release tomorrow.

更新2:我用一个较大的缩略图替换了它，但仍然遇到问题.

Update 2: I replaced it with a larger thumb image, and I'm still having a problem.

更新:如果我非常精确地触摸滑块上的拇指，它似乎仍然可以连续控制.但是为什么会改变这种情况，我如何使其像以前一样进行控制?

Update: It looks like it still controls continuously if I'm super precise about touching the thumb on the slider. But why is this changed, and how can I make it control like before?

我在视图中添加了滑动手势识别器:

I have a swipe gesture recognizer added to my view:

    let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
    swipeRight.direction = UISwipeGestureRecognizer.Direction.right
    self.view.addGestureRecognizer(swipeRight)

稍后，我将UISlider添加到同一视图:

Later on, I add a UISlider to the same view:

        let slider = UISlider()
        let sliderLength:CGFloat = 175
        slider.frame = CGRect(x:0,
                              y:CGFloat(customHeight) - 35,
                              width:sliderLength,
                              height:35)


        slider.minimumValue = -1.2 
        slider.maximumValue = 0.6
        slider.setValue(Float(snowSliderValAdder), animated: false)

        slider.addTarget(self, action: #selector(self.updateSnowSliderValue(_:)), for: .valueChanged)

        view.addSubview(slider)

以前可以正常工作的东西，现在在iOS 13中表现不佳.如果我将滑块缓慢移动，则可以移动它的拇指，但是如果进行任何滑动动作，则滑块上的拇指会停止移动，并且手势被触发.我该如何阻止这种情况的发生?

What used to work fine, now behaves poorly in iOS 13. I can move the thumb on the slider if I move it very slowly, but if I do any kind of a swiping motion, the thumb on the slider stops moving and the gesture is triggered. How can I stop this from happening?

推荐答案

我遇到了相同的问题，并通过执行以下操作设法解决了这个问题:

I had the same issue and managed to resolve it by doing the following:

向您的滑块添加一个不执行任何操作的panGesture，并将其cancelsTouchesInView属性设置为false.

Add a panGesture ,that does nothing, to your sliders and set their cancelsTouchesInView propery to false.

let panGesture = UIPanGestureRecognizer(target: nil, action:nil)
                    panGesture.cancelsTouchesInView = false
                    slider.addGestureRecognizer(panGesture)

现在，您的滑块应该像刀一样滑动，可以切黄油，而不会打滑.

Now your sliders should slide like a knife cutting a butter with no swipe interruption.
