UIButton -setTitle: forState: doesn't seem to work

Question

I'm trying to dynamically update the title of an `IBOutletCollection` of `UIButton`s. I expect the title to be set to - the letter 'S' when selected and - the text "D|S" when disabled and selected. It wasn't working, so I printed out the `titleForState:`s and it looks like the title is not getting set properly. Am I using `setTitle: forState:` correctly? ``` @property (strong, nonatomic) IBOutletCollection(UIButton) NSArray *buttons; ... - (void)updateUI // Calling this from IBAction { for(UIButton *button in self.buttons) { [button setTitle:@"S" forState:UIControlStateSelected]; [button setTitle:@"D|S" forState:UIControlStateSelected|UIControlStateDisabled]; NSLog(@"%@ %@ %@ %@ %d %d", [button titleForState:UIControlStateSelected], [button titleForState:UIControlStateSelected], [button titleForState:UIControlStateNormal], [button titleForState:UIControlStateSelected|UIControlStateDisabled], button.selected, button.enabled); } } ``` Here's the console output: ``` 2013-02-21 21:05:36.0…

Accepted Answer

It's not working because IB sets `attributedTitle` instead of `title`.

Try this instead:

```
NSAttributedString *attributedTitle = [self.myButton attributedTitleForState:UIControlStateNormal];
NSMutableAttributedString *mas = [[NSMutableAttributedString alloc] initWithAttributedString:attributedTitle];
[mas.mutableString setString:@"New Text"];

[self.myButton setAttributedTitle:mas forState:UIControlStateNormal];
```

Or, alternatively:

```
[self.myButton setAttributedTitle:nil forState:UIControlStateNormal];
[self.myButton setTitle:@"New Text" forState:UIControlStateNormal];
```

(The second option won't preserve your formatting.)
