IPhone Libraries
Mose developers collect a number of libraries and Open Source code samples during their career, which they use over and over again.
Here is a list of the IPhone code that I use when building apps, please feel free to send me some suggestions for more?
- TouchJSON
TouchJSON is parser and generator for JSON implemented in Objective C. - Three20
Three20 is an Objective-C library for iPhone developers, featuring a Photo Viewer, Message Composer, Web Images View, Internet aware table view controllers, Better text fields, HTTP disk cache and URL-based navigation. - HTTPRiot
HTTPRiot is a simple REST library designed to make interacting with REST services much easier. It supports GET, POST, PUSH and DELETE requests and HTTP Basic Authentication. HTTPRiot was inspired by John Nunemaker’s excellent httparty Ruby library.
I also have a personal stash of UIKit extensions which i often re-us, I will put them together for a later post
