Storyboard cached?

The way it is.

I run the interface stays in a previous interface, but now storyboard interface has changed, and I have repeatedly run the product-clean again.

Is there a storyboard cache?

I manually create storyboards and specified, the specified code is as follows:

 
/ / Manually load storyboard 
UIStoryboard * storyboard = [UIStoryboard storyboardWithName: @ "Storyboard" bundle: nil]; 

self.viewController = [storyboard instantiateInitialViewController]; 

self.navigationController = [[UINavigationController alloc] initWithRootViewController: self.viewController]; 

self.window.rootViewController = self.navigationController; 

As shown:

Found the cause of the problem, then xcode suggested that the file is locked, and can not be updated. Should this issue.
