推荐答案

当您选择要播放的歌曲时，请阅读在Apple的文档中执行代码。如果您在应用程序的 Info.plist 中将 UIBackgroundModes 键设置为音频，音频将继续播放而背景。

You need to read Executing Code in the Background in Apple's documentation. If you set the UIBackgroundModes key in you app's Info.plist to audio, audio will keep playing while backgrounded.

请参阅上述文档中的声明您支持的后台任务和播放背景音频。

See the sections Declaring the Background Tasks You Support and Playing Background Audio in the aforementioned documentation.
