Good evening, this is Bono.
When using Xcode5, I sometimes get a warning that "Application windows are expected to have a root view controller at the end of the application launch".
If you see "Application windows are expected to have a root view controller
What to do when you get the following warning.
At that time, the following settings should be made.
Set the root view
Open AppDelegate,
[self.window addSubview: viewController.view];
is corrected to the following.
[self.window setRootViewController: viewController];
Does this mean that there must be one root view in the app?
