Programmatically change title of UIButton whose title was set in IB as attributed

Question

I have changed titles of UIButtons before using:

- (void)setTitle:(NSString *)title forState:(UIControlState)state

But I\'ve r

Answer 1

I had to use the following 4 lines to get the attributed font to display. In IB the title is set to plain and not attributed.

// Get the library font
UIFont *termsFont = [MTHGAppearanceController defaultFontOfSize:[MTHGAppearanceController defaultButtonFontSizeForDevice]];
// Set the font attributes required, using our librarby function for setting the colour
NSDictionary *fontAttributes = @{NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle),NSBackgroundColorAttributeName: [UIColor clearColor], NSFontAttributeName: termsFont, NSForegroundColorAttributeName:[UIColor mthg_color255WithRed:128.0f green:128.0f blue:128.0f alpha:1.0f]};
// Configure the text we want displayed using the font set above
NSAttributedString *termsString = [[NSAttributedString alloc]initWithString:@"Terms" attributes:fontAttributes];
// Now finally display the text in the required font
[self.termsButtonOutlet setAttributedTitle:termsString forState:UIControlStateNormal];

Answer 2

Swift - For a red strikethrough font in a button title:

let attributedStringForInvalid = NSAttributedString(string: "I'm Invalid!", attributes: [
  NSStrikethroughStyleAttributeName: true,
  NSForegroundColorAttributeName: UIColor.redColor()
  ])
myButton.setAttributedTitle(attributedStringForInvalid, forState: UIControlState.Normal)

Answer 3

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 .specify first - @property(non atomic,strong)IBOutlet UIButton *mybutton;

then

[myButton setTitle: @"myTitle" forState: UIControlStateNormal];

Answer 4

here's one

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
       action:@selector(aMethod:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Title" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
 [view addSubview:button];

no need to make changes in- (void)setTitle:(NSString *)title

Answer 5

Attributed titles are obtained via

- (NSAttributedString *)attributedTitleForState:(UIControlState)state

and set via

- (void)setAttributedTitle:(NSAttributedString *)title forState:(UIControlState)state

Formatting the NSAttributedString object is a bit complicated, but setting it to nil will clear the title and that's what I needed.
