Question

I need your help. I have been switching from various libraries trying to find the suitable one to integrate Twitter in my application.

A while back i found out that i could use ASIHTTPRequest to send tweets from my app. I need to know if there’s any tutorial or sample code available.

And i have already looked at share-kit and i prefer to integrate Twitter using ASIHTTPRequest

note: I have created my project using ARC, and it shoudl support both iOS4 and 5.

Twitter’s documentation says that you have to make GET or POST HTTP requests with the appropriate form data (key-value pairs). For example, to post a status update, you can do:

NSURL *url = [NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"];
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

[request addRequestHeader:@"Accept" value:@"*/*"];
[request addRequestHeader:@"onnection" value:@"close"];
[request addRequestHeader:@"Content-Type" value:@"application/x-www-form-urlencoded"];
[request addRequestHeader:@"Content-Length" value:@"17"];
[request addRequestHeader:@"Host" value:@"api.twitter.com"];

[request setPostValue:@"User's new status" forKey:@"status"];

// set here completion/error handlers

[request startAsynchronous];

For authetication, you’ll need some kind of OAuth library. Here’s Karl Adam’s MPOAuth, with few additions and corrections by me: https://github.com/H2CO3/MPOAuthiOS

On iOS 5.x, you can use Apple’s default, and easy to use Twitter.framework: http://developer.apple.com/library/ios/#documentation/Twitter/Reference/TwitterFrameworkReference/_index.html
