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:<
Run otool on the excutable.
Go to the build directory:
AppName/build/AppName.build/Release-iphoneos/AppName.build/Objects-normal/armv6/
and run
strings AppName | grep ‘setResult' to know which framework used that particular method.
