objc-appdotnet

A clean, object-oriented API binding for the App.Net API written in Objective-C.

Description

objc-appdotnet is a completely asynhronous Objective-C library that simplifies communicating with the App.Net API in on object oriented manner. All parsing of JSON data is done for you and encompassed in Objective-C classes that can be readily used in your applications.

Usage

To use in your own projects, you will need everything inside the "app.net" folder. That folder contains all App.Net objects as well as the main API interface. JSON parsing is done using JSONKit, which is also included in the project's source. I will soon replace this NSJSONSerialization, but for now still using JSONKit.

The main API entry-point to access the App.Net API is the AppDotNet object. An example of usage is shown in AppDelegate.m of the included project.

AppDotNet *engine = [[AppDotNet alloc] initWithAccessToken:token];

NOTE: You initialize the main AppDotNet interface with an access token for your app. The responses from the App.Net API are then returned to you via the blocks that are passed into each API call. The access token is received after proper OAuth2 authentication of your app, see "Authentication" section below.

Authentication

App.Net uses standard OAuth2 for authentication. This library does not provide functions to do authentication via OAuth2. There are plenty of other libraries that are better suited for this:

You may use the any standard OAuth2 authentication method. All that is required for objc-appdotnet is the access token you receive.

Error Handling

If there is an error with the API request, each call's block parameter "error" will be not nil. The error object is an instance of NSError class. The error will either be an "HTTP" error or an error within the ADN API. Error type is indicated by the domain string "HTTP" or "ADN". Status code of error is also encoded in the NSError object. See the AppDelegate.m implementation for an example on how to handle errors.

Currently there is very little error checking done during the JSON parsing so if things are not properly formatted, it's likely that the app will crash.

Known Limitations & Bugs

  • Currently only App.Net's token, user, and posts API are supported.
  • Annotations and Links are not currently working when writing posts using the writePost method.
  • The includeUser, includeAnnotations, and includeReplies flags for stream methods do not work.
  • Latest App.Net changes include responses that contain a "meta" value. This information is ignored currently.
  • Using JSONKit for JSON parsing instead of NSJSONSerialization

Please let me know if you find any bugs/issues while using this library. I'd be more than happy to hear from you.
