I've recently open-sourced a couple small libraries that I've been using extensively in projects -- lately we've seen several great open-source icon fonts released for the web, including Font Awesome and ionicons.
These fonts are an excellent addition to the iOS developer's toolkit, but there's some work to be done in order to render them as a UIImage or put them in a UILabel.
To make things easier, I've released my method of using these icon fonts in iOS apps, compatible with iOS 5 - 7. You can find the projects on GitHub:
