  7 | h2. Introduction
  8 | 
  9 | This is a simple Objective-C API and GUI to access Twitter. The project includes ready-to-go interfaces for a login screen and a tweet composer.
 10 | 
 11 | The library uses Twitter's XAuth authentication method. This is a new authentication method that does not need a web view to let the user login. Using XAuth you can ask the user for her username and password using a native GUI.
 12 | 
 13 | The API is fully asynchronous and can be easily embedded in any project. There are no dependencies on other libraries.
 14 |

 18 | 
 19 | h2. Requirements
 20 | 
 21 | The code has been developed and tested for iPhone OS 3.0 and higher. It does not use anything specific to 3.0 so it should also work on 2.2.1.
 22 | 
 23 | To use this code you will need to sign up for Twitter API access and then open a support ticket with them to request XAuth access.
 24 | 
 25 | h2. Example Usage
 26 | 
 27 | A full working example is included in the project. The gist of it is here:
 28 | 
 29 | <pre><code>

 48 |    
 49 | 	// Try to get the token from the keychain. If it does not exist then we will have to show the login dialog
 50 | 	// first. In a real application you should store the token in the user's keychain!
 51 | 	
 52 | 	NSData* tokenData = [[NSUserDefaults standardUserDefaults] dataForKey: @"Token"];
