Finding Private API Call _terminateWithStatus

Question

I just received an email from Apple stating my app has been rejected for the call of _terminateWithStatus. I have a few frameworks in the app and believe that could be the culprit.

I have ran otool here is my output

/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
/System/Library/Frameworks/Foundation.framework/Foundation (compatibility version 300.0.0, current version 751.49.0)
/System/Library/Frameworks/UIKit.framework/UIKit (compatibility version 1.0.0, current version 1400.0.0)
/System/Library/Frameworks/CoreGraphics.framework/CoreGraphics (compatibility version 64.0.0, current version 600.0.0)
/System/Library/Frameworks/CoreData.framework/CoreData (compatibility version 1.0.0, current version 320.15.0)
/System/Library/Frameworks/MapKit.framework/MapKit (compatibility version 1.0.0, current version 14.0.0)
/System/Library/Frameworks/CFNetwork.framework/CFNetwork (compatibility version 1.0.0, current version 485.12.7)
/System/Library/Frameworks/SystemConfiguration.framework/SystemConfiguration (compatibility version 1.0.0, current version 379.0.0)
/System/Library/Frameworks/MobileCoreServices.framework/MobileCoreServices (compatibility version 1.0.0, current version 20.0.0)
/System/Library/Frameworks/CoreLocation.framework/CoreLocation (compatibility version 1.0.0, current version 370.3.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 150.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.4.0)
/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current version 227.0.0)
/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation (compatibility version 150.0.0, current version 550.52.0)

I have also run the app through App Scanner but terminateWithStatus is not shown in the output.

Can anyone point me in the right direction on finding this? I have also seen some talk about using nm and grep to find the call. Thanks ahead of time.

SOLVED:

After diving into the build directory:

AppName/build/AppName.build/Release-iphoneos/AppName.build/Objects-normal/armv6/ 

I ran:

strings AppName | grep 'terminateWithStatus'

and returned one result. After some digging, I found GHUnit, testing framework, was making the call. I removed the framework, rebuilt, and ran the string command again without any results.

I hope this helps anyone else searching for a Private API call, it has not been a fun adventure.

You have to run otool on the executable, not on the app wrapper.

For example (sorry for the formatting weirdness):

$ otool -L WriteRoom.app/Contents/MacOS/WriteRoom 

WriteRoom.app/Contents/MacOS/WriteRoom (architecture ppc):
    @executable_path/../Frameworks/Blocks.framework/Versions/A/Blocks (compatibility version 1.0.0, current version 1.0.0)
    /System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 11.0.0)
    /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.3)
