在Swift中获取UIAlertAction的处理程序 [英] Get handler of UIAlertAction in Swift

问题描述

如何在Swift中获取UIAlertAction的处理程序.它在初始化时设置，但是我还没有找到任何可以使操作结束的属性.闭包的类型为(UIAlertAction) -> Void，但是我想获取闭包的内容，这样我就可以像() -> Void这样使用闭包了.这可能吗?感谢您的回答

How is it possible to get the handler of a UIAlertAction in Swift. It is set when initializing however I haven't found any property to get hold on the closure of the action. The closure is of type (UIAlertAction) -> Void however I would like to get the content of the closure so that I have some closure like () -> Void. Is this possible? Thanks for your answers

推荐答案

UIAlertAction类没有公开任何成员/属性.但是，我们可以通过对UIAlertAction进行子类化来自己进行管理，并指定一个名为"actionHandler"的成员来存储它.

There is NO member/property exposed by the UIAlertAction class. However we can manage this by ourselves by subclassing UIAlertAction and have some member named, say, "actionHandler" to store that.
