推荐答案

使用基本的ViewController，以编程方式仅创建底部音乐播放器视图，然后从基本ViewController扩展所有ViewController.因此，您所有的viewcontroller都将获得相同的底部播放视图.

Take a base viewcontroller which will programatically create only bottom music player view, then extend all you viewcontroller from the base viewcontroller. thus all of your viewcontroller will get the same bottom play view.

当心，所有viewcontroller都会有不同的底视图实例，您需要不断更新所有底播放器视图.一种巧妙的方法是使用NSNotification

Beware, all viewcontroller will different instance of the bottom view, you need to keep update all the bottom player view. A neat way to do that is using NSNotification

命名为@"backgroundImageChanged" NSNotification侦听背景图像中的任何更改.应用程序内部触发的所有NSNotification都将由该观察器侦听，并相应地更改背景图像.

Any change in the background image is listened by the @"backgroundImageChanged" NSNotification named. Any NSNotification fired inside the application is listened this observer and background image is changed accordingly.
