ios - UicollectionView 在 swift ios View 之间滚动？

Question

我的收藏 View 运行良好。它显示了照片网格并列出了数百张照片。您可以垂直滑动以滚动浏览所有内容。生活很好。不过，我现在有一个新的要求。我需要能够检测用户何时向左或向右滑动。我需要能够拦截此手势，以便我可以将行为附加到左右滑动，同时保持 Collection View 的垂直滚动功能完整。有什么想法吗？

快速？

如果您在 Xcode 中打开项目，您可以看到详细 View Controller 。它根据所选的集合单元 Controller 从名为cards的plist文件中获取信息

您可以添加左右滑动手势识别器来检测左右滑动。

override func awakeFromNib() {
        super.awakeFromNib()

 // Add Left Swipe Gesture
        let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(SomeClass.respondToSwipeGesture(_:)))
        swipeLeft.direction = UISwipeGestureRecognizerDirection.Left
        self.addGestureRecognizer(swipeLeft)

        // Add Right Swipe Gesture
        let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(SomeClass.respondToSwipeGesture(_:)))
        swipeRight.direction = UISwipeGestureRecognizerDirection.Right
        self.addGestureRecognizer(swipeRight)
     }

    // This function detects Swipe direction and perform action
    func respondToSwipeGesture(gesture: UIGestureRecognizer) {

        if let swipeGesture = gesture as? UISwipeGestureRecognizer {
            switch swipeGesture.direction {
            case UISwipeGestureRecognizerDirection.Right:
                print("Swiped right")
                rightSwipeAction()

            case UISwipeGestureRecognizerDirection.Left:
                print("Swiped left")
                leftSwipeAction()

            default:
                break
            }
        }
    }
