swift 3使用特殊字符的電話＃

Question

我有問題使用＃在電話中，在控制檯顯示(tel://*155*222222*123%23)，我相信問題是使用＃。我查了一下，有人說不允許在電話中使用特殊字符。

var code = String() 
var ID = String() 
var Card = String() 
@IBAction func ChargePhone(_ sender: Any) { 
    ID = "123" 
    ID = ID.trimmingCharacters(in: CharacterSet.whitespacesAndNewlines) 
    Card = "222222" 
    code = "*155*" 


     var RESULT = "\(code)\(Card)*\(ID)#" 

     RESULT = RESULT.addingPercentEncoding(withAllowedCharacters: CharacterSet.urlQueryAllowed)! 
     if let url = URL(string: "tel://\(RESULT)"), UIApplication.shared.canOpenURL(url) { 
      if #available(iOS 10, *) { 
       UIApplication.shared.open(url) 
      } else { 
       UIApplication.shared.openURL(url) 
      } 
}

手機應用程序不允許在iOS上的電話號碼重定向上使用特殊字符。
