在 iOS 9 及以前，如果显示磨砂，该 view 为 qmui_backgroundView 的 subview，是一个 _UIBackdropView，如果显示背景图，则返回 qmui_backgroundView 自身，因为 _UINavigationBarBackground 本身就是一个 UIImageView。

@warning 如果要以 view 的方式去修改 UINavigationBar 的背景，由于不同的 iOS 版本，qmui_shadowImageView 和 qmui_backgroundContentView 的层级关系不同，所以为了效果的统一，建议这种情况下操作 qmui_backgroundView 会好过于操作 qmui_backgroundContentView。
