'How to change font of UIButton with Swift

I am trying to change the font of a UIButton using Swift...

myButton.font = UIFont(name: "...", 10)

However .font is deprecated and I'm not sure how to change the font otherwise.

Any suggestions?

Solution 1:^[1]

Use titleLabel instead. The font property is deprecated in iOS 3.0. It also does not work in Objective-C. titleLabel is label used for showing title on UIButton.

myButton.titleLabel?.font =  UIFont(name: YourfontName, size: 20)

However, while setting title text you should only use setTitle:forControlState:. Do not use titleLabel to set any text for title directly.

Solution 2:^[2]

For Swift 3.0:

button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 16)

where "boldSystemFont" and "16" can be replaced with your custom font and size.

Solution 3:^[3]

Dot-notation is awesome ?

btn.titleLabel?.font = .systemFont(ofSize: 12)

Solution 4:^[4]

As mentioned by many here you can set the font with something like:

button.titleLabel?.font = .systemFont(ofSize: 19.0, weight: .bold)

Just make sure your button has default style though for this to be applicable, otherwise the above gets ignored by the system.

Solution 5:^[5]

If you need to change only size (Swift 4.0):

button.titleLabel?.font = button.titleLabel?.font.withSize(12)

Solution 6:^[6]

You don't need to force unwrap the titleLabel to set it.

myButton.titleLabel?.font = UIFont(name: YourfontName, size: 20)

Since you're not using the titleLabel here, you can just optionally use it and if it's nil it will just be a no-op.

I'll also add as other people are saying, the font property is deprecated, and make sure to use setTitle:forControlState: when setting the title text.

Solution 7:^[7]

In Swift 5, you can utilize dot notation for a bit quicker syntax:

myButton.titleLabel?.font = .systemFont(ofSize: 14, weight: .medium)

Otherwise, you'll use:

myButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)

Solution 8:^[8]

From the documentation:

The font used to display text on the button. (Deprecated in iOS 3.0. Use the font property of the titleLabel instead.)

Solution 9:^[9]

If you're having font size issues (your font isn't responding to size changes)...

@codester has the right code:

myButton.titleLabel!.font =  UIFont(name: YourfontName, size: 20)

However, my font size wasn't changing. It turns out that I asking for a font that didn't exist ("HelveticaNeue-Regular"). It wasn't causing a crash, but seemed to be just ignoring that font statement because of it. Once I changed the font to something that does exist, changes to "size: x" did render.

Solution 10:^[10]

we can use different types of system fonts like below

myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
myButton.titleLabel?.font = UIFont.italicSystemFont(ofSize:UIFont.smallSystemFontSize)
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: UIFont.buttonFontSize)

and your custom font like below

    myButton.titleLabel?.font = UIFont(name: "Helvetica", size:12)

Solution 11:^[11]

Take a look here.

You should set the font of the button's titleLabel instead.

myButton.titleLabel!.font = UIFont(name: "...", 10)

Solution 12:^[12]

You should go through the titleLabel property.

button.titleLabel.font

The font property has been deprecated since iOS 3.0.

Solution 13:^[13]

This works in Swift 3.0:

btn.titleLabel?.font = UIFont(name:"Times New Roman", size: 20)

Solution 14:^[14]

If you are setting AttributedString to the UIButton then you can do the below thing.

let attributedText = NSAttributedString(string: "Hello", attributes: [NSAttributedStringKey.font: UIFont(name: "Calibri", size: 19)])
okayButton.setAttributedTitle(attributedText, for: .normal)

Solution 15:^[15]

Example: button.titleLabel?.font = UIFont(name: "HelveticaNeue-Bold", size: 12)

If you want to use defaul font from it's own family, use for example: "HelveticaNeue"
If you want to specify family font, use for example: "HelveticaNeue-Bold"

Solution 16:^[16]

This way doesn't work now:

 btn.titleLabel?.font = UIFont(name: "Helvetica", size:12)

This works:

 btn.titleLabel?.font = UIFont.init(name: "Helvetica", size:12)

Solution 17:^[17]

this work for me, thanks. I want change text size only not change font name.

var fontSizeButtonBig:Int = 30

btnMenu9.titleLabel?.font = .systemFont(ofSize: CGFloat(fontSizeButtonBig))

Solution 18:^[18]

To do this using storyboard, go to the attributes inspector while your button is selected. In the third field from the top ("Title") select "Attributed". This will bring up the font drop-down list where you can easily change the font.
