您是否有任何方式打开一个UIPresentationController,当向左滑动触发并点击编辑？
func tableView(tableView: UITableView,editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
let delete = ....
let edit = UITableViewRowAction(style: .Normal,title: "Edit") { action,index in
//OPEN UIPresentationController HERE
}
return [delete,edit]
}
解决方法
和@patchdiaz一样,我不是100％肯定你想做什么.但是,这个代码块可能足以实现您的目标：
override func tableView(tableView: UITableView,editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
let edit = UITableViewRowAction(style: .Normal,index in
// OPEN UIPresentationController HERE
let vc = UIViewController(nibName: nil,bundle: nil)
vc.view.frame = CGRect(x: 0,y: 0,width: 100,height: 200)
vc.view.backgroundColor = UIColor.orangeColor()
vc.modalPresentationStyle = .Popover
let popover = vc.popoverPresentationController!
let cell = tableView.cellForRowAtIndexPath(indexPath)!
var cellAbsolutePosition = cell.superview!.convertPoint(cell.frame.origin,toView: nil)
cellAbsolutePosition.x = cell.frame.width - 60
popover.sourceRect = CGRect(origin: cellAbsolutePosition,size: cell.frame.size)
popover.sourceView = tableView
self.presentViewController(vc,animated: true,completion: nil)
}
return [edit]
}
它会在“编辑”按钮位置显示一个popover权限,如下所示：
