ios - 在 SWIFT 中处理 UIActionSheet 上的事件

Question

我正致力于在 SWIFT 中为 iOS8 创建 UIActionSheet。我有一个工作代码，但我坚持处理操作表的按钮点击。

我当前的代码是:

    var actionSheet =  UIAlertController(title: "Publish this Image ?", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
    actionSheet.addAction(UIAlertAction(title: "Tweet", style: UIAlertActionStyle.Cancel, handler: nil))
    actionSheet.addAction(UIAlertAction(title: "WhatsApp", style: UIAlertActionStyle.Default, handler: nil))
    actionSheet.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Destructive, handler: nil))
    self.presentViewController(actionSheet, animated: true, completion: nil)

如何处理按钮点击事件？？ 我是否需要以任何方式使用 handle 参数？？

你可以尝试这样的事情:

    var actionSheet =  UIAlertController(title: "Publish this Image ?", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
    actionSheet.addAction(UIAlertAction(title: "Tweet", style: UIAlertActionStyle.Default, handler: { (ACTION :UIAlertAction!)in
        //your code here...
        }))
    actionSheet.addAction(UIAlertAction(title: "WhatsApp", style: UIAlertActionStyle.Default, handler: { (ACTION :UIAlertAction!)in
        //your code here...
    }))
    actionSheet.addAction(UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil))
    self.presentViewController(actionSheet, animated: true, completion: nil)
