Extends UIFont with named font constructors so you don't end up hard-coding the font names in your app. Also provides the same functionality for your custom fonts.

Built-in Font Usage

Include UIFont+NTNamedFonts.h in your PCH file. Once it's there you will have autocomplete for any built-in font. You can then set fonts like this:

self.anyLabel.font = [UIFont avenirBookOfSize:12.0];

Additionally each font has an NS_AVAILABLE attribute added (currently supporting iOS 6.0 and iOS 7.0.)

Custom Font Usage

In order to support custom fonts, NTNamedFonts can help you generate the required .h/m files. Simply add the following to your didFinishLaunchingWithOptions:

[UIFont detectCustomFontsShowingAlert:YES];

If it detects any custom fonts have been aded or removed it will output the contents of UIFont+CustomFonts.h and UIFont+CustomFonts.m to the log. Simply copy and paste the contents into your project and you are good to go! detectCustomFontsShowingAlert: only does anything in DEBUG builds, so you can safely leave this in your code without paying any performance penalty for appstore builds.

Installation

This is dead simple. If you are using cocoapods add 'pod NTNamedFonts' to your podfile. If you are doing things old school, add UIFont+NTNamedFonts.h and UIFont+NTNamedFonts.m to your project and enjoy!

Bootstrapping

The NTNamedFontsBootstrap project contains code used to build this project. It detects builtin fonts and builds a map of font names to versions. Additionally, it is used to generate builtin font declarations in UIFont+NTNamedFonts.h

I've mapped the font versions for iOS 6.0 and iOS 7.0. If you are supporting older iOS versions and would like to have the NS_AVAILABLE attribute reflect that version you can use the bootstrap code to help you do that. Run the app and execute updateBuiltinFontVersionsWithVersion for the version you are testing with. Copy and paste the output into the builtinFontVersions method in UIFont+NTNamedFonts.m and then run again, this time running buildHeader. Paste those results over the named fonts declatations in UIFont+NTNamedFonts.h. The same approach will work to add new fonts when a new version of iOS comes out.
