[英]Swift create left, right swipe with long press tableview row cell movable
In my scenario, I am trying to create a UITableView cell enable left and right swipe with tableView cell long-press to movable within in particular section.在我的场景中,我正在尝试创建一个 UITableView 单元格,通过长按 tableView 单元格启用左右滑动以在特定部分内移动。 Here, I can only able to do trailing and leading swipe, don't know how to move cells within a section.
在这里,我只能进行尾随和前导滑动,不知道如何在一个部分内移动单元格。
Below Code For Leading and Trailing下面的前导和尾随代码
func tableView(_ tableView: UITableView, leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let deleteAction = UIContextualAction(style: .normal, title: "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("OK, marked as Delete")
success(true)
})
if #available(iOS 13.0, *) {
deleteAction.image = UIImage(systemName: "delete")
} else {
// Fallback on earlier versions
deleteAction.image = UIImage(named: "delete")
}
deleteAction.backgroundColor = .red
return UISwipeActionsConfiguration(actions: [deleteAction])
}
func tableView(_ tableView: UITableView,trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
let modifyAction = UIContextualAction(style: .normal, title: "Edit", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
print("Update action ...")
self.showaddMilestone()
success(true)
})
modifyAction.image = UIImage(named: "edit")
modifyAction.backgroundColor = .green
return UISwipeActionsConfiguration(actions: [modifyAction])
}
a) enable drag interation on table view b) set drag and drop delegates a) 在表格视图上启用拖动交互 b) 设置拖放委托
tableView.dragInteractionEnabled = true
tableView.dragDelegate = self
tableView.dropDelegate = self
func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath:
IndexPath, to destinationIndexPath: IndexPath) { }
extension TableView: UITableViewDropDelegate,UITableViewDragDelegate {
func tableView(_ tableView: UITableView, itemsForBeginning session: UIDragSession, at indexPath: IndexPath) -> [UIDragItem] {
return [UIDragItem(itemProvider: NSItemProvider())]
}
func tableView(_ tableView: UITableView, dropSessionDidUpdate session:
UIDropSession, withDestinationIndexPath destinationIndexPath: IndexPath?)
-> UITableViewDropProposal {
if session.localDragSession != nil {
return UITableViewDropProposal(operation: .move, intent: .insertAtDestinationIndexPath)
}
return UITableViewDropProposal(operation: .cancel, intent: .unspecified)
}
func tableView(_ tableView: UITableView, performDropWith coordinator:
UITableViewDropCoordinator) {
}
}
