Programmatically change attributed title of UIButton

Question

I want to programmatically change the title of an UIButton which has an attributed title. The button is created in IB. I do not want to change the attributes just the title/text.

I've tried the code below but cannot find a way to change the title of the NSAttributedString.

NSAttributedString *attributedString = [self.deleteButton attributedTitleForState:UIControlStateNormal];

// How can I change title of attributedString without changing the attributes?

[self.deleteButton setAttributedTitle:attributedString forState:UIControlStateNormal];

Thank you!

Answer 1

Partially you have the answer.

 NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithAttributedString:[_ deleteButton attributedTitleForState:UIControlStateNormal]];

[attributedString replaceCharactersInRange:NSMakeRange(0, attributedString.length) withString:@"Your new string"];

[_ deleteButton setAttributedTitle:attributedString forState:UIControlStateNormal]; 

Instead of creating NSAttributedString create NSMutableAttributedString then you can just set the string like this.

Answer 2

Swift 3 answer:

if let attributedTitle = yourButton.attributedTitle(for: .normal) {
    let mutableAttributedTitle = NSMutableAttributedString(attributedString: attributedTitle)
    mutableAttributedTitle.replaceCharacters(in: NSMakeRange(0, mutableAttributedTitle.length), with: "New title")
    yourButton.setAttributedTitle(mutableAttributedTitle, for: .normal)
}
