Swift - UITableView editActionsForRowAtIndexPath打开UIPresentationController时点击编辑

Question

嗨有什么办法打开UIPresentationController时，左刷卡被触发，它是点击Edit？

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] 
}

与@patchdiaz相同，我不是100％确定你想要做什么。然而，这个代码块可能足以进行定制，以实现自己的目标：

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? { 
    let edit = UITableViewRowAction(style: .Normal, title: "Edit") { action, 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] 
} 

它会显示一个酥料饼就在这样的“编辑”按钮位置：

不知道你在问什么。像这样的东西应该工作（这是在斯威夫特2）：

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> 
     [UITableViewRowAction]? { 
      let delete = ... 
      let edit = UITableViewRowAction(style: .Normal, title: "Edit") { [weak self] _ in 
       let viewController = ... 
       viewController.modalPresentationStyle = .Custom 
       self?.presentViewController(viewController, animated: true, completion: nil) 
      } 
      return [delete, edit] 
    }
