我有一个tableView,其中一些单元格有阴影。 当我做一个平移手势来查看任何单元格的行动作时,tableview会剪切单元格边界,直到我做出关闭行动作的手势。
我已将clipsToBounds
设置为false
单元格的contentView及其超级视图,同样在tableview中
自定义单元格的代码:
var isExpanded: Bool = false
@IBOutlet weak var shadowView: UIView!
@IBOutlet weak var fullContainer: UIView!
override func awakeFromNib() {
super.awakeFromNib()
reloadUI()
}
func reloadUI() {
contentView.superview?.clipsToBounds = false
contentView.clipsToBounds = false
fullContainer.layer.masksToBounds = true
fullContainer.layer.cornerRadius = 8
shadowView.layer.masksToBounds = false
shadowView.layer.cornerRadius = 8
shadowView.layer.shadowOpacity = 1.0
shadowView.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)
shadowView.layer.shadowPath = UIBezierPath(roundedRect: fullContainer.bounds, cornerRadius: 8).cgPath
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
isExpanded = selected
reloadUI()
}
带有tableview的viewcontroller的代码:
extension SecondViewController: UITableViewDelegate {
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let action = UITableViewRowAction(style: .destructive, title: "Delete") { (action, indexPath) in
tableView.deleteRows(at: [indexPath], with: .automatic)
}
return [action]
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.reloadRows(at: [indexPath], with: .automatic)
selectedIndex = indexPath.section
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return section != 0 ? 8 : 1
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView()
view.clipsToBounds = false
return view
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if selectedIndex == indexPath.section {
return 120
}
return 108
}
}
SecondViewController
也有这段代码,因为它有一个pan识别器,用于在视图控制器之间用手势进行更改
extension SecondViewController: UIGestureRecognizerDelegate {
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
if gestureRecognizer == recognizer || otherGestureRecognizer == recognizer {
return false
}
return true
}
func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
if gestureRecognizer == recognizer{
for cell in tableView.visibleCells {
let location = gestureRecognizer.location(in: cell.contentView)
if cell.contentView.layer.contains(location) {
return false
}
}
return true
}
return true
}
}
剪切边界的TableViewCell:
答案 0 :(得分:2)
这看起来像是UITableView中的错误。可以通过以下扩展名来解决:
extension UITableView {
func fixCellBounds() {
DispatchQueue.main.async { [weak self] in
for cell in self?.visibleCells ?? [] {
cell.layer.masksToBounds = false
cell.contentView.layer.masksToBounds = false
}
}
}
}
只需在调用reloadRows
/ insertRows
/ deleteRows
等之后调用它即可。
tableView.reloadRows(at: <index paths>, with: .automatic)
tableView.fixCellBounds()
之前:
之后:
