如何从任何NSObject子类显示UIAlertController? [英] How do i display UIAlertController from any NSObject subclass?

问题描述

我有一个遗留的代码库正在管理，它需要显示来自各地的警报消息.这是很糟糕的做法，需要进行重构，但这不会很快发生.使用iOS 9时，我需要能够启动&忘记警报视图，并为我管理视图的显示和排队.

I have a legacy codebase I am managing, which needs to display alert messages from all over the place. This is terrible practice and is in need of a refactor, but that isn't going to happen any time soon. With iOS 9 I need the ability to fire & forget an alert view, and have the view display and queuing managed for me.

推荐答案

正如其他人所建议的那样，这通常是不好的做法，并且违反了MVC原则.但是，如果您管理的是旧版代码库，而根本无法重构所有内容，那么我就创建了该类，使您可以像对待旧的UIAlertView一样对待UIAlertController，它可以管理显示任何类的警报，还可以对队列进行排队提醒您...

As other people have suggested, this is generally bad practice and breaks the MVC principles. However, if you're managing a legacy codebase and refactoring everything simply isn't an option, i made this class which lets you treat UIAlertController like the old UIAlertView, it manages displaying the alert from any class, and also queue's alerts for you...
