Set UIButton title UILabel font size programmatically

Question

I need to set the font size of the title UILabel of a UIButton programmatically.

Answer 1

To support the Accessibility feature in UIButton

extension UILabel
{
   func scaledFont(for font: UIFont) -> UIFont {
        if #available(iOS 11.0, *) {
            return UIFontMetrics.default.scaledFont(for: font)
        } else {
            return font.withSize(scaler * font.pointSize)
        }
    }
    func customFontScaleFactor(font : UIFont) {
        translatesAutoresizingMaskIntoConstraints = false

         self.adjustsFontForContentSizeCategory = true
         self.font = FontMetrics.scaledFont(for: font)
    }
}

You can can button font now.

UIButton().titleLabel?.customFontScaleFactor(font: UIFont.systemFont(ofSize: 12))

Answer 2

Swift:

shareButton.titleLabel?.font = UIFont.systemFontOfSize(size)

Answer 3

button.titleLabel.font = <whatever font you want>

For the people wondering why their text isn't showing up, if you do

button.titleLabel.text = @"something";

It won't show up, you need to do:

[button setTitle:@"My title" forState:UIControlStateNormal]; //or whatever you want the control state to be
