Iphoneguiexample doesn't work

Hi,

When I try to compile IphoneGuiExample, I get an error :
Xcode stops at
UIApplicationMain(nil, nil, nil, [NSString stringWithUTF8String:appDelegateClassName.c_str()]);
and terminal writes :
libc++abi.dylib: terminating with uncaught exception of type NSException

Any ideas please ?
I really need make native ios code worked with openframeworks to finish a project
I work with xcode 5.1.1, ios7.1 and ofx0.8.3

Thanks for help
