Question

我正在尝试从Unity3D项目登录Facebook。我用我的iPhone 6来测试它。一切都在游戏中运作良好但在登录完到Facebook后，游戏无法再次出现并终止。 XCode将以下代码带到屏幕上。 UIApplicationMain部分（argc ...已标记，它表示＆＃39;主题1：信号SIGABRT＆＃39;

请帮助我花了好几个小时但却找不到问题。

// 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\n", &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;

这是输出：
