检测UicollectionViewCompositionallayout中正交部分上的userefent/pan/scroll

发布于 2025-01-24 13:27:50 字数 231 浏览 0 评论 0原文

我使用构图布局在CollectionView的正交部分上使用自动滚动。我需要在用户手动滚动该部分后立即使自动滚动计时器无效。我可以使用scrollviewDidbeGindRagging/scrollViewWillBegIndeCelerating，但是ScrollView委托永远不会在正交部分上调用。如果在这种情况下有人有任何解决方法可以检测用户滚动事件，那将是有帮助的。谢谢。

尝试了几种解决方案后，我找到了最好和最简单的解决方案。
我在UicollectionViewCell中添加了一个UipangeSturerecogniser，以收听用户PAN事件。在选择器中，我只是使计时器无效。就是这样！
另外，我们需要通过覆盖gesturercognizer（_：syseReRecognizeSimultanealywith：）来返回true。
这就是我添加到UicollectionViewCell类中的内容：

class CustomCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: .zero)
        pan = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:)))
        pan.delegate = self
        self.addGestureRecognizer(pan)
    }
    
    @objc private func handlePan(_ pan: UIPanGestureRecognizer) {
        delegate?.invalidateTimer()
    }
}

extension CustomCell: UIGestureRecognizerDelegate {
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }
}

这样，每次用户尝试滚动时，我都会使自动滚动计时器无效

After trying out several solutions, I found the best and the simplest solution.
I added a UIPanGestureRecogniser to the UICollectionViewCell to listen to user pan events. In the selector, I just invalidate the timer. That's it!
Also we need to return true by overriding gestureRecognizer(_:shouldRecognizeSimultaneouslyWith:) so that the vertical scroll and horizontal scrolls works properly.
This is what I added to the UICollectionViewCell class:

class CustomCell: UICollectionViewCell {
    override init(frame: CGRect) {
        super.init(frame: .zero)
        pan = UIPanGestureRecognizer(target: self, action: #selector(handlePan(_:)))
        pan.delegate = self
        self.addGestureRecognizer(pan)
    }
    
    @objc private func handlePan(_ pan: UIPanGestureRecognizer) {
        delegate?.invalidateTimer()
    }
}

extension CustomCell: UIGestureRecognizerDelegate {
    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }
}

With this, every time the user tries to scroll, I invalidate the autoScroll timer
