在UItableviewcell中的pangesture,表滚动不在swift中工作
问题描述:
我想在UItableviewCell中左右划动UIview,并且我已经使用UIPanGestureRecognizer来实现此目的,下面是附加的源代码。然而,当我试图滚动UItableview时,我的Uiview可以上下移动,无法滚动到UItableviewcell,即Superview.Can任何人都可以告诉我如何管理?提前致谢?在UItableviewcell中的pangesture,表滚动不在swift中工作
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CardSwipeTVCell") as! CardSwipeTVCell
let tapGesture : UIPanGestureRecognizer!
tapGesture = UIPanGestureRecognizer(target: self, action: #selector(ViewController.tapEdit(_:)))
cell.cardView.addGestureRecognizer(tapGesture!)
cell.cardView.tag = indexPath.row
tapGesture!.delegate = self
cell.selectionStyle = .none
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
}
func tapEdit(_ recognizer: UIPanGestureRecognizer)
{
print(recognizer.view?.tag as Any)
let sender = recognizer.view?.tag as Any
let indexPath = IndexPath(row: sender as! Int, section: 0)
let cell = self.cardTableView.cellForRow(at: indexPath) as? CardSwipeTVCell
cell?.cardView.backgroundColor = UIColor.black
let card = recognizer.view!
let point = recognizer.translation(in: view)
card.center = CGPoint(x: (cell?.center.x)! + point.x, y: (cell?.center.y)! + point.y)
if recognizer.state == UIGestureRecognizerState.ended
{
UIView.animate(withDuration: 0.3, animations: {
card.center = (cell?.center)!
})
}
}
另一个问题是,当我点击第二个单元我的视图消失了?你的帮助将非常感激。
答
override func gestureRecognizerShouldBegin(gestureRecognizer: UIGestureRecognizer) -> Bool {
if let panGestureRecognizer = gestureRecognizer as? UIPanGestureRecognizer {
//let translation = panGestureRecognizer.translation(in: superview!)
let translation = panGestureRecognizer.translationInView(superview)
if fabs(translation.x) > fabs(translation.y) {
return true
}
return false
}
return false
}
将上面的委托方法添加到您的类中。这将停止pangesture而tableview视图垂直滚动。
