项目更新迭代好些版本了 突然收到如下被拒原因 苹果真的是随机抽查某个功能的吗？

苹果拒绝的邮件内容是这样的：

Guideline 2.1 - Information Needed

这个是2.1大礼包里面的 照着看按要求， 这次主要是我们的项目里面有音频模块，做了后台播放功能 其实就是这里打开了开关， 当然直接在这里去掉该项勾选也是可以的，但是我不勾选就没法后台播放了啊 这对我们的项目来说是不行的 ：

Xcode的设置

解决方法：按照苹果的邮件回复
*我收到的这个邮件，不需要重新上传ipa了 ，按要求录制了一段视频 传到附件里面 然后回复邮件说明了一下。

我的回复内容附上

关于我录制的视频是什么样子的 就是用自己的手机 录屏功能，录制从
点开app-找到音频功能-播放音频-按home键回到桌面-这时还在继续播放，结束录制。

大概是当天中午我回复的这些内容给苹果，当天晚上九点十点左右就审核通过了。【开心】
