"prefs:root" or "App-Prefs:root"

iOS 苹果审核也是看心情的吗？已经上线几个版本了，新版本提交审核居然被查出来了！

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.

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.

Next Steps

To resolve this issue, please revise your app to provide the associated functionality using public APIs or remove the functionality using the "prefs:root" or "App-Prefs:root" URL scheme.

If there are no alternatives for providing the functionality your app requires, you can file an enhancement request.

自我检测一把：

工具：mac 终端 

命令：

grep "App-Prefs:root" -r +工程目录

或者

grep "Prefs:root" -r +工程目录

示例：

yoowei$ grep "App-Prefs:root" -r /Users/yoowei/Desktop/yooweiWorking/yoowei

Binary file /Users/yoowei/Desktop/yooweiWorking/yoowei/yoowei/Vendors/yytt/yytt.framework/yytt matches

另外.svn里面以前的记录也有，对应的删掉即可。
