Just to make sure I'm not doing anything stupid, I statically declare and initialise my root VC like this inside my cinderapp.cpp file (not its real name)

1. FirstViewController *sFirstVC = [[UIStoryboard storyboardWithName:@"Storyboard" bundle:[NSBundle mainBundle]] instantiateViewControllerWithIdentifier:@"FirstVC"];

and then create the app like this at the end of the same file

1. CINDER_APP(CircularBellsApp,
2.   RendererGl(RendererGl::Options().msaa(1)),
3.   [](App::Settings* settings) {
4.     settings->setHighDensityDisplayEnabled(true);
5.     settings->setMultiTouchEnabled();
6.     settings->setFrameRate(60.0f);
7.     settings->prepareWindow(Window::Format().rootViewController(sFirstVC));
8.   });

I also had to reimplement AppDelegateImpl to take care of certain things but I don't think this is related, as I switched back to Cinder's implementation, and the bug is still occurring.

This is in my Cinder app class

void CircularBellsApp::launch() {

  const auto &args = getCommandLineArgs();

  int argc = (int)args.size();

  char* argv[argc];

  for( int i = 0; i < argc; i++ )

    argv[i] = const_cast<char *>( args[i].c_str() );

    ::UIApplicationMain( argc, argv, nil, ::NSStringFromClass( [CBAppDelegateImpl class] ) );

}

and this is the app delegate I'm reimplementing.

So after much hair pulling and code deletion of every extension/catagory/UIAppearance setup in our app we discovered that the issue in our case was that the root view controller for the app was being initialized in the app delegates init method. We have been able to reproduce this in a sample app. heres the code that breaks.

1. @UIApplicationMain  
2. class AppDelegate: UIResponder, UIApplicationDelegate {  
3.   var window: UIWindow?  
4.   var controller: UIViewController  
5.   
6.   override init() {  
7.        window = UIWindow()  
8.        controller = UINavigationController(rootViewController: UIViewController())  
9.   }  
10.   func application(_ application: UIApplication, willFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {  
11.        window?.rootViewController = controller  
12.        window?.makeKeyAndVisible()  
13.   
14.        return true  
15.   }  
16. }  

Any ideas?

(useless) UPDATE This is the only other "useful" reference for this case. As far as Google Translate understands, this person has no idea how to fix this either.

(useful) UPDATE Irritatingly, the iosNativeControls sample works.

(interesting) UPDATE It seems that initialising the native view controller through UIStoryboard was not such a good idea. I had to change that line to
