How to change font of UIButton with Swift
IosUibuttonSwiftUifontIos Problem Overview
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?

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 - Ios
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 - Ios
Dot-notation is awesome
btn.titleLabel?.font = .systemFont(ofSize: 12)
Solution 4 - Ios
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.

If you need to change only size (Swift 4.0):
button.titleLabel?.font = button.titleLabel?.font.withSize(12)

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.

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)

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.)

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 - Ios
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 - Ios
Take a look here.
You should set the font of the button's titleLabel instead.
myButton.titleLabel!.font = UIFont(name: "...", 10)
Solution 12 - Ios
You should go through the titleLabel
property.
button.titleLabel.font
The font
property has been deprecated since iOS 3.0.
Solution 13 - Ios
This works in Swift 3.0:
btn.titleLabel?.font = UIFont(name:"Times New Roman", size: 20)
Solution 14 - Ios
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 - Ios
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 - Ios
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)

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))

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.
