UIFont is a powerful tool for customizing the appearance of your UIButton titles. With just a few lines of code, you can give your buttons a unique and eye-catching look. In this article, we will explore the different ways you can enhance your UIButton titles with custom fonts.
First, let's start by creating a basic UIButton with a default title. We will use the title "Click Me" for our button.
```
let button = UIButton()
button.setTitle("Click Me", for: .normal)
```
By default, the system font will be used for the button title. While this may work for some cases, it's always nice to have the option to use a custom font. So, let's see how we can do that.
The first step is to add your custom font file to your project. This can be done by dragging and dropping the font file into your Xcode project. Make sure to check the "Copy items if needed" option to ensure the font file is added to your project.
Next, we need to add the font name to our project's Info.plist file. Open the Info.plist file and add a new row with the key "Fonts provided by application". In the value column, add the name of your font file, including the file extension.
Now that we have our font added to our project, we can use it in our UIButton. To do this, we will use the UIFont class and specify the name of our font.
```
let customFont = UIFont(name: "CustomFontName", size: 17)
button.titleLabel?.font = customFont
```
In the above example, we have specified the name of our custom font and also set the font size to 17 points. You can experiment with different font sizes to find the perfect size for your button title.
But what if you want to use different fonts for different states of your UIButton? For example, you may want to use a different font for the normal state and a different font for the highlighted state. This can be easily achieved by using the `setTitle(_:for:)` method with different control states.
```
button.setTitle("Click Me", for: .normal)
button.setTitle("Click Me", for: .highlighted)
```
You can also use a different font for the disabled state by setting the font for the `.disabled` control state.
```
button.setTitle("Click Me", for: .disabled)
```
Another way to enhance your UIButton title with custom fonts is by using attributed strings. This allows you to have more control over the appearance of your title, including different font styles, sizes, and colors.
```
let attributes: [NSAttributedString.Key: Any] = [
.font: UIFont(name: "CustomFontName", size: 17),
.foregroundColor: UIColor.red,
.underlineStyle: NSUnderlineStyle.single.rawValue
]
let attributedString = NSAttributedString(string: "Click Me", attributes: attributes)
button.setAttributedTitle(attributedString, for: .normal)
```
In the above example, we have specified the font, color, and underline style for our button title. You can add more attributes to the dictionary to further customize the appearance of your title.
Lastly, if you want to use a custom font for all your UIButtons, you can do so by setting the `appearance` of the UIFont class in your AppDelegate's `didFinishLaunchingWithOptions` method.
```
let customFont = UIFont(name: "CustomFontName", size: 17)
UIButton.appearance().titleLabel?.font = customFont
```
This will ensure that all your UIButtons will use the specified custom font for their titles.
In conclusion, customizing the font of your UIButton titles is a simple and effective way to enhance the appearance of your app. Whether you want to use a different font for different states or create an attributed string with various attributes, the possibilities are endless. So go ahead and experiment with different fonts to find the perfect one for your UIButtons. Happy coding!
