I am trying to login Facebook from my Unity3D project. I use my iPhone 6 to test it. Everything works well in the game but after login is done to facebook, the game cannot come to foreground again and it terminates. XCode brings below code to screen. The part UIApplicationMain(argc… is marked and it says ‘thread 1: signal SIGABRT’
Please help I spent hours but could not spot the problem.
// Hack to work around iOS SDK 4.3 linker problem
// we need at least one __TEXT, __const section entry in main application .o files
// to get this section emitted at right time and so avoid LC_ENCRYPTION_INFO size miscalculation
static const int constsection = 0;
void UnityInitTrampoline();
// WARNING: this MUST be c decl (NSString ctor will be called after +load, so we cant really change its value)
const char* AppControllerClassName = "UnityAppController";
int main(int argc, char* argv[])
{
@autoreleasepool
{
UnityInitTrampoline();
UnityInitRuntime(argc, argv);
RegisterMonoModules();
NSLog(@"-> registered mono modules %p
", &constsection);
RegisterFeatures();
// iOS terminates open sockets when an application enters background mode.
// The next write to any of such socket causes SIGPIPE signal being raised,
// even if the request has been done from scripting side. This disables the
// signal and allows Mono to throw a proper C# exception.
std::signal(SIGPIPE, SIG_IGN);
UIApplicationMain(argc, argv, nil, [NSString stringWithUTF8String:AppControllerClassName]);
}
return 0;
And this is the output:
