Applications are expected to have a root view controller at the end of application launch

Question

I get the following error in my console:

Applications are expected to have a root view controller at the end of application launch

Answer 1

I also had this error but unlike any of the answers previously listed mine was because i had uncommented the method 'loadView' in my newly generated controller (xcode 4.2, ios5).

 //Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView  
{
}

It even told me that the method was for creating the view programmatically but i missed it because it looked so similar to other methods like viewDidLoad that i normally use i didn't catch it.

To solve simply remove that method if you are not programmatically creating the view hierarchy aka using nib or storyboard.
