* QMUINavigationButton 有两部分组成：
|
* 一部分是 UIBarButtonItem (QMUINavigationButton)，提供比系统更便捷的类方法来快速初始化一个 UIBarButtonItem，推荐首选这种方式（原则是能用系统的尽量用系统的，不满足才用自定义的）。
|
* 另一部分就是 QMUINavigationButton，会提供一个按钮，作为 customView 给 UIBarButtonItem 使用，这种常用于自定义的返回按钮。
|
* 对于第二种按钮，会尽量保证样式、布局看起来都和系统的 UIBarButtonItem 一致，所以内部做了许多 iOS 版本兼容的微调。
