Hello everyone, Given that the repository has not been updated for a long time.

Recently I found an alternative solution from JKCategories.

This repository also provides a series of methods (JKCategories/UIKit/UIDevice/UIDevice+Hardware.m) to obtain the application device model.

Hope these are useful to everyone.

大家好，鉴于该存储库很久没有维护更新了。

最近，我在一个开源框架 JKCategories 找到了相同的解决方案。

这个开源框架提供了一系列的 categorires 分类，它里面也提供了获取应用设备型号的方法，该实现源码位于 JKCategories/UIKit/UIDevice/UIDevice+Hardware.m。最重要的是，这个库到目前为止还在维护中。

希望这些对大家有用。
