这是我的代码:

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! imageUserCell

    let coolGesture = UILongPressGestureRecognizer(target: self, action: #selector(detailedPerson.makeItCoolAction(_:)))

    coolGesture.minimumPressDuration = 0.5
    coolGesture.view?.tag = 4

    cell.addGestureRecognizer(coolGesture)

这是功能代码:

   func makeItCoolAction(sender: UIGestureRecognizer){

    print(sender.view?.tag)
    print("Photo cooled")

}

控制台打印相同的值:0,这是默认值。我强烈需要将 indexPath.row 值传递给 makeItCoolAction 但我看到 UIGestureRecognizer 没有 tag 属性但 .view 属性有它,正如您在代码中看到的那样。

我已将 makeItCoolAction 发件人从 UILongPressGestureRecognizer 更改为 UIGestureRecogizer 并且它仍然继续打印 0 值。

此时视图为零:

coolGesture.view?.tag = 4

添加手势后尝试设置点击,它具有如下视图:

cell.addGestureRecognizer(coolGesture)
coolGesture.view?.tag = 4
