Uibutton Font Size Isn't Changing

UIButton font size isn't changing

In Xcode 13 ,UIButton has four type are Plain,Grain,Tinted,Filled .When you create a button in storyboard , button type automatically set with Plain that means new UIButton configurations is on. If you want to old behaviour , you must set style plain to default.

Or , If you want one of the style above . You need to set font like

button.titleTextAttributesTransformer = UIConfigurationTextAttributesTransformer { incoming in
  var outgoing = incoming
  outgoing.font = UIFont.systemFont(ofSize: 50)
  return outgoing
 }

changing font size of UIButton

The reason that the code you're posting isn't working is probably because Arial isn't present in iOS. You can change the properties of a UIButton's titleLabel just like any other instance of UILabel. Read about that here.

So, you can change the font size with something like:

button.titleLabel.font = [UIFont systemFontOfSize:14.0];

You can choose a font by name, but not all fonts are available on iOS. Here's a list of ones that are.

Can't change custom UIFont size on the UIButton

Interestingly enough, it turned out to be my Mac. When I gave my friend to install them, he had no issues.
My Mac is on the old side, so maybe this was the reason. Here are the specs:

**Mac:** MacBook Pro 15" (Late 2008)
**Processor:**  2.4 GHz Intel Core 2 Duo
**Memory:** 4 GB 1067 MHz DDR3
**Graphics:** NVIDIA GeForce 9600M GT 256 MB

How to change font of UIButton with Swift

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.

How insert new font and force the change in UIButton?

You need to add MyriadPro font to your project and to info.plist file for key UIAppFonts (Fonts provided by application). Then you can use your code to set font,

[botaoCadastrar.titleLabel setFont:[UIFont fontWithName:@"MyriadPro" size:18]];

Reason:

The MyriadPro font is not iOS default font. You can find default font list here,

1. iOS 6 - http://support.apple.com/en-us/ht5484
2. iOS 7 - http://support.apple.com/en-us/ht5878

UIButton does not resize height correctly with custom font when sizeToFit is called

In case anyone has the same problem and comes across this, I figured out a solution simply by subclassing UIButton. Then, I just modified layoutSubviews so that the titleLabel bounds equaled the button's subviews, and it no longer cut off the top part of the font. Not sure if it's the best way, but it works.

- (void)layoutSubviews
{
    [super layoutSubviews];
    self.titleLabel.bounds = self.bounds;
}

How to change the size of an SF icon in a UIButton

You can use the Default Symbol Configuration settings on the UIButton in the Attributes Inspector to accomplish the same thing. All Credit to Andrew Kirna below. Thanks dude!

Success!!! I finally figured out how to do this, thanks to a great article on SF Symbols. It was certainly buried in there.

It would be really nice to resize your button images in storyboard wouldn't it? I thought so at least.

1. Add IconButton.swift to your project in Xcode.

   import UIKit
   
   @IBDesignable
   class IconButton: UIButton {
       @IBInspectable var pointSize:CGFloat = 30.0
   
       override func layoutSubviews() {
           super.layoutSubviews()
           if #available(iOS 13.0, *) {
               let config = UIImage.SymbolConfiguration(pointSize: pointSize)
               setPreferredSymbolConfiguration(config, forImageIn: .normal)
           } else {
               // Fallback on earlier versions
           }
       }
   }
   

2. Create a button in storyboard with an SF icon as the image.

3. Go to the identity inspector and make the class of your button IconButton

4. Go to the attribute inspector and enter in your point size. Note that this the height of the icon x
   3/4. I wanted a 40 x 40 icon, so my point size was 30.

5. See your icon update in storyboard and laugh happily that you didn't spend 3 hours figuring this out :D
