It supports OAuth 1.0a and it's fully compatible with MKNetworkKit existing classes, allowing you to simply inherit `RSOAuthEngine` instead of `MKNetworkEngine` to get OAuth support. 8 | 9 | ## Usage 10 | 11 | If you already have a project using MKNetworkKit, just add the contents of the `RSOAuthEngine` directory to your project and change all classes that inherit from `MKNetworkEngine` to inherit from `RSOAuthEngine` instead. Whenever you need to send an OAuth signed request, replace calls to `enqueueOperation` with `enqueueSignedOperation`. 12 | 13 | If you're not currently using MKNetworkKit, follow the instructions to add it to your project [here](http://blog.mugunthkumar.com/products/ios-framework-introducing-mknetworkkit/) first, then add **RSOAuthEngine** as written in the previous paragraph. **Important**: although not mentioned in the instructions, MKNetworkKit also requires Security.framework. 14 | 15 | ### Usage Details 16 | 17 | A common OAuth flow using **RSOAuthEngine** should go like this: 18 | 19 | 1. Create a class that inherits from **RSOAuthEngine**. 20 | 2. Init your class using one of the defined initializers that include your Consumer Key and Secret. 21 | 3. Send a signed operation to get a request token. 22 | 4. Fill the request token using `fillTokenWithResponseBody:type` (use `RSOAuthRequestToken` as type). 23 | 5. Redirect the user to the authorization page and wait for the callback. 24 | 6. Fill the request token (again) using `fillTokenWithResponseBody:type` (use `RSOAuthRequestToken` as type), this time using the parameters received in the callback. 25 | 7. Send another request to get an access token. 26 | 8. Fill the access token using `fillTokenWithResponseBody:type` (use `RSOAuthAccessToken` as type). 27 | 9. From now on, all requests sent with `enqueueSignedOperation` will be signed with your tokens. 28 | 29 | Alternatively you could use `setAccessToken:secret` after initialization to define a previously stored access token. If you need or want to use xAuth instead of the request token/authorize workflow, please take a look at the Instapaper demo. 30 | 31 | ### XOAuth 32 | 33 | This library also supports generating XOAuth strings (to use with Gmail SMTP and IMAP servers, for example). Just call `generateXOAuthStringForURL:method` with the desired URL and method (GET/POST). 34 | 35 | ## Twitter Demo 36 | 37 | 38 | 39 | 42 | 60 | 61 |

About

44 | 45 |

This sample project demonstrates how to use RSOAuthEngine to authenticate with Twitter. It includes a basic engine that implements Twitter's OAuth authentication flow and allows you to post a tweet. It also shows you how to persist the OAuth access token in the Keychain. The Twitter engine should not be considered production code, and is only included to demonstrate RSOAuthEngine.

Building

48 | 49 |

To build the demo project, follow these steps:

50 | 51 |
    52 |
  1. In the project directory, run git submodule update --init to retrieve MKNetworkKit (added to the project as a submodule).
    2. 53 |
  2. Put your consumer key and secret at the top of RSTwitterEngine.m and remove the #error macro. If you don't have a consumer key/secret, register an app at https://dev.twitter.com/apps to get a pair. Important: you need to add a dummy callback URL to your app when registering, otherwise Twitter won't allow you to send a callback URL in the OAuth request.
