Project configuration

iOS 1.需要打开支持后台模式 在主项目的info.plist中添加

<key>UIBackgroundModes</key>
<array>
	<string>audio</string>
	<string>fetch</string>
</array>

或者在xcode打开主项目的Signing&Capabilities下的Background Modes下勾选上两个对勾（Audio、Airplay、and Picture in Picture和Background fetch）

2.第一次发布AppStore的时候需要提供使用后台的场景视频介绍，不然审核会被拒掉。
