但第二警報功能，程序運行，但是當點擊該按鈕時，錯誤

崩潰

錯誤：的libC++ abi.dylib：與類型的未捕獲的異常NSException

@IBAction func buttonPressed(sender: UIButton) { 

    let title = "Display Title" 
    let message = "You just clicked on Display Alert" 
    let okText = "OK" 

    let title1 = "Display Title" 
    let message1 = "You just clicked on Display Alert" 
    let okText1 = "OK" 

    let alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.Alert) 
    let okayButton = UIAlertAction(title: okText, style: UIAlertActionStyle.Cancel, handler: nil) 
    alert.addAction(okayButton) 

    let alert1 = UIAlertController(title: "title1", message: "message1", preferredStyle: UIAlertControllerStyle.Alert) 
    let okayButton1 = UIAlertAction(title: okText1, style: UIAlertActionStyle.Cancel, handler: nil) 
    alert.addAction(okayButton1) 


    presentViewController(alert, animated: true, completion: nil) 
    presentViewController(alert1, animated: true, completion: nil) 

}

可以同時顯示一個ONY UIAlertController終止。

Answer 2

您可以使用TKSwarmAlert自定義控件，但不會有關閉按鈕。
