How to change UIButton font with Swift

Question

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

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

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

Any suggestions?

Answer 1

titleLabel this use titleLabel . The font property is deprecated in iOS 3.0. This also does not work in Objective-C. titleLabel is the label used to display the title on the UIButton .

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

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

Answer 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.

Answer 3

The dot notation is awesome (swift 4.2) 👌

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

Answer 4

You do not need to force the titleLabel to deploy to set it.

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

Since you are not using titleLabel here, you can just use it, and if it is zero, it will be just no-op.

I will also add, as other people say, the font property is deprecated and remember to use setTitle:forControlState: when setting the title text.

Answer 5

From the documentation :

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

Answer 6

If you have problems with the font size (your font does not respond to resizing) ...

@codester has the correct code:

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

However, my font size did not change. Turns out I'm asking for a font that wasn't there ("HelveticaNeue-Regular"). It didn't crash, but it seems to just ignore this font statement because of this. As soon as I changed the font to what exists, the changes in "size: x" were displayed.

Answer 7

Take a look here .

Instead, you should set the font for the titleLabel button.

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

Answer 8

This works in Swift 3.0:

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

Answer 9

You must go through the titleLabel property.

button.titleLabel.font

The font property has been deprecated since iOS 3.0.

Answer 10

If you set the AttributedString to UIButton, then you can do the following.

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

Answer 11

If you only need to resize ( Swift 4.0 ):

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

Answer 12

we can use various types of system fonts as shown 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 own font as below

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

Answer 13

Now this method does not work:

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

It works:

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

Answer 14

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

• If you want to use the font defaul from your own family, use, for example: "HelveticaNeue"
• If you want to specify a family font, use, for example: "HelveticaNeue-Bold"

Answer 15

this work is for me, thanks. I want to change only the size of the text, and not change the font name.

 var fontSizeButtonBig:Int = 30 

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

Answer 16

In Xamarin.iOS, you can write C # code as follows:

myButton.TitleLabel.Font = UIFont.FromName ("Helvetica-Bold", 33f);
