Guideline 2.5.1 - Performance - Software Requirements
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.
解决方法：
搜索"prefs:root=" 把使用了这个关键字的代码改成
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
