自定義編輯按鈕分段控制TableViews

Question

我有一個tableViewController與segmentedControl。一切都很好，數據顯示爲每個桌面視圖上的假設，我可以在每個段控件之間切換。

我想爲每個segmentControl的TableView添加一個Swipe Delete特性。但是我希望Segment1擁有1個按鈕，並且Segment2擁有2個按鈕。

例：

Segment 1 
    Button: More 
Segment 2 
    Button: More 
    Button: Delete 

我怎麼能做到這一點，在我不斷收到點擊時崩潰的應用程序上SEGMENT1一個空白的時刻。無論如何要隱藏Segment1的空白區域/按鈕？

override func tableView(tableView: UITableView, editingStyleForRowAtIndexPath  
    indexPath: NSIndexPath) -> UITableViewCellEditingStyle { 

    var table:UITableViewCellEditingStyle = UITableViewCellEditingStyle.None 

    switch (self.segmentControl.selectedSegmentIndex) { 
    case 0: 
     table = UITableViewCellEditingStyle.Delete 
    case 1: 
     table = UITableViewCellEditingStyle.Delete 
    default: 
     break 
    } 

    return table 

} 

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath 
indexPath: NSIndexPath) -> [AnyObject]? { 

    var moreRowAction = UITableViewRowAction() 
    var deleteRowAction = UITableViewRowAction() 

    switch (self.segmentControl.selectedSegmentIndex) { 
    case 0: 
     moreRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "More", handler:{action, indexpath in 
      println("MORE•ACTION"); 
     }); 

    case 1: 
     moreRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "More", handler:{action, indexpath in 
      println("MORE•ACTION"); 
     }); 
     moreRowAction.backgroundColor = UIColor(red: 0.298, green: 0.851, blue: 0.3922, alpha: 1.0); 

     deleteRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Delete", handler:{action, indexpath in 
      println("DELETE•ACTION"); 
     }); 
    default: 
     break 
    } 

    return [deleteRowAction, moreRowAction]; 
}

返回的情況下，0一個UITableViewRowAction，如果1返回兩個UITableViewRowAction，試試這個

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? { 

    var moreRowAction = UITableViewRowAction() 
    var deleteRowAction = UITableViewRowAction() 

    switch (self.segmentControl.selectedSegmentIndex) { 
    case 0: 
     moreRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "More", handler:{action, indexpath in 
      println("MORE•ACTION"); 
     }); 
     return [moreRowAction]; 
    case 1: 
     moreRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "More", handler:{action, indexpath in 
      println("MORE•ACTION"); 
    }); 
     moreRowAction.backgroundColor = UIColor(red: 0.298, green: 0.851, blue: 0.3922, alpha: 1.0); 

     deleteRowAction = UITableViewRowAction(style: UITableViewRowActionStyle.Default, title: "Delete", handler:{action, indexpath in 
      println("DELETE•ACTION"); 
     }); 
     return [deleteRowAction, moreRowAction]; 
    default: 
     break 
    } 

    return [deleteRowAction, moreRowAction]; 
}
