Question

I have been working for 4 months on an app, its pretty complex and works fine.
Now suddenly, I added a new class and did some changes to the MainWindow.xib with all my views there and now I just get a plain white view when I launch it with simulator.
I even stripped it down completely to nothing but the appdelegate and one simple plain view with a button. So basically I’ve got an app with nothing but an appDelegate managing a tabBar, launching with one simple view, no frameworks no nothing and I still get a white app.

There must be an option somewhere that I must have activated for the running of app in simulator but I can’t figure it out.

Thank you

This happens if you have forget to add the root view controller to the main window, either by [self.window addSubview:yourRootViewController.view], or by self.window.rootViewController = yourRootViewController; (Note: If you are doing it by code).

And, you are seeing the white color because main window’s backgroundColor is white.
