app store - iOS App Rejected : non-public APIs

Question

The same app has already been approved twice before but after some changes like set the image view and submitting the app again, Apple rejected my app for following errors:

Performance - 2.5.1

Your app uses or references the following non-public APIs:

setResult: nextStarIndex

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.

How can a user test his/her application if it contains Private API's?

I am not using setResult: and nextStarIndex code anywhere in my project so what should I do?

Answer 1

The last time I encountered this was because of a namespace collision between methods in my code and private methods in the Cocoa API. You can also use grep to find out exactly where you're using those selectors:

grep -R 'setResult:' *
