Auto change the font size to fit the button in swift

Question

I have tried this but it didn\'t work, the text is out of the button boundaries.

button.titleLabel!.adjustsFontSizeToFitWidth = true
button.titleLabel!.numberOfL         


        

Answer 1

This worked for me:

 button.titleLabel?.font = UIFont(name: "Avenir Next", size: 20)
    button.titleLabel?.adjustsFontSizeToFitWidth = true
    button.titleLabel?.numberOfLines = 1
    button.titleLabel?.minimumScaleFactor = 0.1
    button.clipsToBounds = true

Answer 2

Adjust font size to fit width

Swift

self.button.titleLabel?.adjustsFontSizeToFitWidth = true

Objective-C

[self.button.titleLabel setAdjustsFontSizeToFitWidth:YES];

Answer 3

You can try this:

1.define the title size based on the current font size of your button

let nsTitle = NSString(string:"yourButtonTitle")
let font = button.titleLabel?.font
let titleSize = nsTitle.sizeWithAttributes([NSFontAttributeName:font])

2.check whether your title fits the button title label :

if titleSize.width > button.titleLabel?.bounds.width{

    //set the appropriate font size

}else{

    //set the appropriate font size or do nothing
}

Answer 4

UIButton font scaling can be very fickle, I've had problems with it in the past. What I did was make the number of lines equal to 1, which worked for me.
