ios - Unity Facebook 插件在登录后终止应用程序(iOS)

Question

我正在尝试从我的 Unity3D 项目登录 Facebook。我用我的 iPhone 6 来测试它。游戏中一切正常，但在登录 facebook 后，游戏无法再次进入前台并终止。 XCode 将以下代码显示在屏幕上。 UIApplicationMain(argc... 部分被标记为“线程 1:信号 SIGABRT”

请帮助我花了几个小时但未能发现问题。

// 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:
