UIButton that resizes to fit its titleLabel

Question

I have a UIButton that I add to my view controller\'s view in a storyboard. I add centering constraints to position it and leading space constraints to limit it

Answer 1

Got same issue. It happens only if UIButton's titleLabel has more than one line. Is it a bug in UIKit?

My Swift solution:

class ResizableButton: UIButton {    
    override var intrinsicContentSize: CGSize {
        let labelSize = titleLabel?.sizeThatFits(CGSize(width: frame.size.width, height: CGFloat.greatestFiniteMagnitude)) ?? .zero
        let desiredButtonSize = CGSize(width: labelSize.width + titleEdgeInsets.left + titleEdgeInsets.right, height: labelSize.height + titleEdgeInsets.top + titleEdgeInsets.bottom)

        return desiredButtonSize
    }
}
