推荐答案

涉及到一些事情.

您必须在两个音乐播放器(应用程序音乐播放器和iPod音乐播放器)之间进行选择:

You have to choose between two music players, the application music player and the iPod music player:

+ (MPMusicPlayerController *)applicationMusicPlayer;
+ (MPMusicPlayerController *)iPodMusicPlayer;

如果选择iPodMusicPlayer，音乐将继续在后台播放，并且用户可以使用iPod(或音乐)应用程序将其停止.

If you choose the iPodMusicPlayer, music will continue to play in the background and the user can stop it using the iPod (or Music) app.

如果选择applicationMusicPlayer，默认情况下，当您将音乐发送到后台时，音乐将停止.如果要继续播放，则必须在Info.plist文件中设置UIBackgroundMode来告诉系统您应该继续运行.

If you choose the applicationMusicPlayer, by default the music will stop when you get sent to the background. If you want to continue playing, you'll have to set UIBackgroundMode in your Info.plist file to tell the system you should continue to run.
