Problem with Controller from Storyboard

[hegerworld]

I have a problem I do not understand, with the storyboard.
I would like to change a UIImageView from another controller:

ViewController 1:

ViewController2 * = hvc [self.storyboard instantiateViewControllerWithIdentifier: @ "hvc"];
[hvc load background];

ViewController 2:

- {(Void) load background
[backroundImage setImage:appDelegate.background];

or:

[backroundImage setImage:nil];

}

The problem is, he does not change the picture. it remains as it was. Even if I set it to nil, it is not responding.
With instantiateViewControllerWithIdentifier he also finds the correct controller, but nothing happened. A bug in the storyboard? Did any of you an idea?

Ok, Read the Manual:

Instance Methods

instantiateInitialViewController
Instantiates and returns the initial view controller in the view controller graph.

- (id)instantiateInitialViewController

This method creates a new instance of the initial view controller each time you call it.

The best way is a NSNotificationCenter, that works!
