Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.

Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.

用到私有的API方法：

终端，cd到项目目录下

然后grep -r prefs .        注意后面有一个点

这时可以找到被拒地方。
