So recently we have found some really useful open source libraries and utilities for iPhone development that have saved us a lot of time, and we thought we would share then with you.

TDBadgedViewCell is a great solution for adding badges to UITableView cells. The badges can be used to show numerical data such as items unread or high scores. Essentially it’s a subclass of UITableViewCell, it’s very easy to use and can be downloaded from github here.

JSON is a common format for web service responses Using the SBJSON library it’s very easy to work with JSON data for iPhone. You can find it here.

If you think your table views are just too square for the iPhone’s nice rounded aesthetic, try using RoundedTableView. A very elegant and efficient way to create tables as subviews with smooth rounded corners. It works straight out of the box.
