第四章 滑動刪除

本項目是《beginning iOS8 programming with swift》中的項目學習筆記==》所有筆記目錄

1.    實現下面的方法，自動打開滑動刪除功能：

override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) { 
}

2. 自定義右滑菜單項

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
    // 分享項
    let shareAction = UITableViewRowAction(style: .Default, title: "Share") { (action, indexPath) -> Void in
        // 選擇分享目標
        let shareMenu = UIAlertController(title: nil, message: "Share using", preferredStyle: .ActionSheet)
       
        let twitterAction = UIAlertAction(title: "Twitter", style: .Default, handler: nil)
        let facebookAction = UIAlertAction(title: "Facebook", style: .Default, handler: nil)
        let emailAction = UIAlertAction(title: "Emain", style: .Default, handler: nil)
        let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
       
        shareMenu.addAction(twitterAction)
        shareMenu.addAction(facebookAction)
        shareMenu.addAction(emailAction)
        shareMenu.addAction(cancelAction)
       
        self.presentViewController(shareMenu, animated: true, completion: nil)
    }
   
    // 刪除項（實現了這個方法須要本身寫刪除項）
    let deleteAction = UITableViewRowAction(style: .Default, title: "Delete") { (action, indexPath) -> Void in
        // 從數據源中刪除
        // ...
       
        self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
    }
   
    // 設置背景色
    shareAction.backgroundColor = UIColor.orangeColor()
    deleteAction.backgroundColor = UIColor.blueColor()
   
    return [shareAction, deleteAction]
}
