Ios 触摸移动停止CADisplayLink动画

在触摸移动中处理动作时，我的CADisplayLink动画暂停。是否可以在后台运行我的CADisplayLink动画？ 在moveBigPoints（）中，我用手指触摸移动bezier路径的所有选定（大）点。。。当我这样做时，CADisplayLink动画暂停

override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?){

    if ((animated == false || animationIsPaused == true) && fourFingersIsOn == false) {
        view.isMultipleTouchEnabled = false

        //test if there are bigPoints:
        if(allLinesCounterActual >= 0 &&  (draggedPointIndex != nil)) {
                if(bigPointsBuffer.contains(allLines[allLinesCounterActual].linePoints[draggedPointIndex!])) {
                    thereAreBigPoints = true
                }

        }
        //action if there are bigPoints:
        if(drawOrMove.selectedSegmentIndex == 1 && doubleTap == false && thereAreBigPoints == true) {

            bigPointsHaveMoved = true

            for touch in touches {
                var localPointBuffer = CGPoint()
                if moveBigPointsFirst == false {
                    localPointBuffer = firstLocalPoint
                    moveBigPointsFirst = true
                } else {
                    localPointBuffer = localPointBigPoints
                }
                localPointBigPoints = touch.location(in: view)
                var translation = CGPoint()
                translation.x = localPointBigPoints.x - localPointBuffer.x
                translation.y = localPointBigPoints.y - localPointBuffer.y
                moveBigPoints(translation: translation)
            }
        }

override func touchesMoved（touch:Set，带有事件：UIEvent？）{
if（（动画==假| |动画==真）和&fourFingersIsOn==假）{
view.isMultipleTouchEnabled=false
//测试是否存在重大问题：
如果（AllLinesInterActual>=0&（draggedPointIndex！=nil））{
if（bigPointsBuffer.contains（allLines[AllLinesInterActual].linePoints[draggedPointIndex！]））{
有两点=正确
}
}
//如果存在重大问题，则采取措施：
如果（drawOrMove.selectedSegmentIndex==1&&doubleTap==false&&thereAreBigPoints==true）{
bigPointsHaveMoved=true
接触{
var localPointBuffer=CGPoint（）
如果moveBigPointsFirst==false{
localPointBuffer=firstLocalPoint
moveBigPointsFirst=true
}否则{
localPointBuffer=localPointBigPoints
}
localPointBigPoints=touch.location（在：视图中）
var translation=CGPoint（）
translation.x=localPointBigPoints.x-localPointBuffer.x
translation.y=localPointBigPoints.y-localPointBuffer.y
moveBigPoints（翻译：翻译）
}
}

你必须做的恰恰相反。如果你必须在Touch中进行大量处理，请在后台移动。非常感谢，但是我如何在Touch中执行我的操作在后台移动+请发布你的TouchsMoved实现这是我的代码，在movingBigPoints（）中，我移动所有选定项（大-）用手指触摸点-这会导致CADisplayLink延迟您需要更多代码吗？
