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:<
I had the same situation with you. Now, the app is ready for sale. I hope I will help you to solve that problem.
"Your app uses or references the following non-public APIs: cancelAction:, defaultInstance "
My solved Steps:
(1) grep -R 'defaultInstance' *
the CrashReporterSDK matches so i remove it .
(2) grep -R 'cancelAction:' * it matches some project function names. I also resolve them.
(3) I suggest that before using "grep -R", you should remove the project's "build document files", so "grep -R" will give us more useful information.
