Add a custom font to your app and use it in your app’s interface.
Your app isn't limited to the custom fonts provided by iOS. If your company has its own branded font, for example, you can use it in your app. Add the font file that contains your font to your app bundle, then use your font the same way you use any of the iOS-provided custom fonts.
Add the Font File to Your Xcode Project
To add a font file to your Xcode project, select File > Add Files to “Your Project Name” from the menu bar, or drag the file from Finder and drop it into your Xcode project. You can add True Type Font (.ttf) and Open Type Font (.otf) files. Also, make sure the font file is a target member of your app; otherwise, the font file will not be distributed as part of your app.
Register Your Font File with iOS
After adding the font file to your project, you need to let iOS know about the font. To do this, add the key "Fonts provided by application" to Info.plist (the raw key name is
UIApp). Xcode creates an array value for the key; add the name of the font file as an item of the array. Be sure to include the file extension as part of the name.
Each font file you add to your project must be listed in this array; otherwise, the font will not be available to your app.
Use Your Custom Font in Interface Builder
After you add the font file to your Xcode project and its Info.plist, you can begin assigning the font to UI objects like
UILabel and UITextField. If you’re using Interface Builder, assign the UI object’s Font setting to your custom font using the Attribute Inspector.
Use Your Custom Font in Source Code
You can create an instance of your custom font in source code. To do this, you need to know the font name. However, the name of the font isn’t always obvious, and rarely matches the font file name. A quick way to find the font name is to get the list of fonts available to your app, which you can do with the following code:
Once you know the font name, create an instance of the custom font using
UIFont. If your app supports Dynamic Type, you can also get a scaled instance of your font, as shown here:
