presentViewController in AppDelegate with delay in iOS8

Question

So I had a full working solution in iOS7 that displays a LoginViewController via presentViewController in the AppDelegate\'s didFinishLaunching.

Basically I am doing so

Answer 1

Also a hack (for now), but just one line of code

Add the view of the view controller you're presenting to the window before presentation

UIViewController *viewController = [[UIViewController alloc] init];
[viewController.view setBackgroundColor:[UIColor greenColor]];

//  Temporary iOS8 fix for 'presentation lag' on launch
[self.window addSubview:viewController.view];

[self.window.rootViewController presentViewController:viewController animated:NO completion:nil];

If you are presenting a navigation controller than add the navigation controller's view instead of its top view controller.
