is it possible to update UIButton title/text programmatically?

I have a UIButton, that when pressed, brings up a new view where the user can change some settings. When the view is dismissed, I'd like to update the title/text of the UIButton to reflect the new state. I'm calling:

[myButton setTitle: @"myTitle" forState: UIControlStateNormal];
[myButton setTitle: @"myTitle" forState: UIControlStateApplication];
[myButton setTitle: @"myTitle" forState: UIControlStateHighlighted];
[myButton setTitle: @"myTitle" forState: UIControlStateReserved];
[myButton setTitle: @"myTitle" forState: UIControlStateSelected];
[myButton setTitle: @"myTitle" forState: UIControlStateDisabled];

But it never seems to change from the original text/title as specified in IB.

Do you have the button specified as an IBOutlet in your view controller class, and is it connected properly as an outlet in Interface Builder (ctrl drag from new referencing outlet to file owner and select your UIButton object)? That's usually the problem I have when I see these symptoms.

Edit: While it's not the case here, something like this can also happen if you set an attributed title to the button, then you try to change the title and not the attributed title.

@funroll is absolutely right. Here you can see what you will need Make sure function runs on main thread only. If you do not want deal with threads you can do like this for example: create NSUserDefaults and in ViewDidLoad cheking condition was pressed button in another View or not (in another View set in NSUserDefaults needed information) and depending on the conditions set needed title for your UIButton, so [yourButton setTitle: @"Title" forState: UIControlStateNormal];
