I'm relatively new to Objective-C and am completely new to xAuth. Can somebody show me how or lead me to a tutorial to get a request access token pair and make a request to a URL given username, password, consumer_key, and consumer_secret?
I'm really foggy with this, and I don't even know why I get a access token pair (why two tokens, and how to both of them come into play?). Also, I already looked through a bunch of tutorials, but all of the good ones are for Twitter, and use some kind of Twitter engine. (I'm using xAuth for Foursquare, and their documentation can be found here.)
Thanks!
MGTwitterEngine is a great place for example code. You can use the OAuthConsumer project to help making xAuth calls.
If you checkout MGTwitterEngine.m (shown on Github) you can see in the function
- (NSString *)getXAuthAccessTokenForUsername:(NSString *)username password:(NSString *)password
creates an OAConsumer object with consumerKey and Secret and then creates an OAMutableURLRequest object, you'd use Foursquare's info there.
You should then be able to create a NSURLConnection with that request and then get your results in your standard delegate method, a la URL Loading System

I'm using the Javascript SDK inside a node.js (Express) App.
Connecting Users works fine, but the connection does not persist between page reloads.
Is this the default behaviour, or is the User supposed to stay connected in new requests?
Do I have to use OAuth token authentication and if so, how can this be done with the JS-SDK?
Inside the "Permission"-Popup, Users are already logged in with soundlcoud, though.
(just have to click the "connect" button each time)
Figured I'd share my answer for those who are unsatisfied with the current answers for automated oauth:
Retrieving access_token:
I had to define get and set cookie functions and then I use the functions to set and retrieve a function holding the access token. I'm not going to give these functions for conciseness but you can easily find them with a google search. I then use this line of code to get the SC access token (once the user has authenticated for the first time)
SC.accessToken()
Setting token:
So this is kind of just an elephant in the room in my opinion that for some reason no one has mentioned. How in the **** do you connect w/ SC using the access token? Do you set it as oauth param? On each call pass it? Well, after experimenting with putting the parameter in every single place I could think, I found out you have to do something like this:
SC.initialize({
client_id: '[removed for security reasons]',
client_secret: '[removed for security reasons]',
redirect_uri: '[removed for security reasons]',
access_token: getCookie("sc_lm2"),
scope: 'non-expiring'
});
//Where "sc_lm2" is the name of my cookie
Hope the helps! Took me a while to figure this out for such a simple thing
EDIT
Using PHP and Wordpress:
$json = wp_remote_get("http://api.soundcloud.com/users/[user_id]/tracks.json?client_id=[client_id]");
$soundcloudData = json_decode($json['body'],true);
(substitue cURL functionality if you're not using Wordpress). #krafty I assume you would just change the endpoint from "/tracks" to "/users" but I can't say I have ever really needed to grab anything but tracks using the Soundcloud API. Hope this helps, though I'm not sure I fully understand what it is that you are trying to accomplish (or rather, how exactly you're going about it) - are you trying to allow user logins? If you want to explain fully what you're trying to accomplish and the steps you're taking I'd be happy to take a crack at it.
Yep, this is the way to do it, officially. :)
For the Next SoundCloud site, we store the token in localStorage (until the user logs out, of course). In each AJAX request to the API from the front end, we put the oauth token in a request header:
jqXHR.setRequestHeader('Authorization', 'OAuth ' + the_oauth_token);
I found a good tutorial for building Facebook membership Authentication website which demo file is here > http://niftyandcrackerjack.com/sites/default/files/Test.zip
I wonder this example does not use access token to retrieve Facebook User Info. It use classes inherits from the masterpage. As I am new to ASP.NET, I don't know how to retrieve Facebook user info. Can someone give me and suggestion or explain...... Thanks,
My finding so far indicate that basic information cannot be accessed unless one has either 'userid' or 'username' as in this post.
If one has to try and fetch basic information using following url, then access_token is needed
http://graph.facebook.com/me
Perform an HTTP GET to https://graph.facebook.com/{userid} or HTTP GET to https://graph.facebook.com/{username}
Examples: Click the link below to see the JSON response.
https://graph.facebook.com/4
https://graph.facebook.com/zuck
Pretty cool, eh? And no token needed to get at this public info.
You can get more info on this here: https://developers.facebook.com/docs/reference/api
I am using Graph API in my application. I am fetching user's facebook wall feeds using graph API also getting details of particular post i.e (Like count,Comments etc).
but i want to allow user to Like and Comment any post from the application itself.
what is the request format for that?
Please help me or give any pointers.

You would be well served to check out the Publishing section of the documentation. It provides information such as this.
One example is liking, which is defined as:
Method: /OBJECT_ID/likes
Description: Like the given object (if it has a /likes connection)
Arguments: none
Basically, just initiate a Graph API call to something like:
[facebookObject requestWithGraphPath:#"98423808305/likes" andDelegate:self];
That will "like" a picture from Coca-Cola (ID taken from the documentation).
Edit 1
According to the documentation:
Most write operations require extended permissions for the active user. See the authentication guide for details on how you can request extended permissions from the user during the authentication step.
Are you sure you have enough privileges? Unfortunately the documentation is very unclear as to whether it serves the dual purpose of liking the object and returning the likes already on that object.
Edit 2
I did some more research into what could be causing this and came across this question and answer that indicated that the code I posted above using requestWithGraphPath:: should work. However, it does not due to a bug on Facebook's Bug Tracker.
Unfortunately, it looks like there is no way to "like" an object via the Graph API, which seems very strange to me. Perhaps it is possible with the legacy REST API instead of the Graph API?
Edit 3
Well, it looks like your best bet is the stream.addLike method of the legacy REST API which you can still call using the Facebook iOS SDK. You should be able to use the stream.addLike method to "like" something in the "stream". Unfortunately, it doesn't appear to support photos, videos, etc. Only posts and comments.
Finally i found the solution for LIKE option
We should use following method for like option.
-(void) requestWithGraphPath:(NSString *)graphPath
andParams:(NSMutableDictionary *)params
andHttpMethod:(NSString *)httpMethod
andDelegate:(id <FBRequestDelegate>)delegate
graphPath = /OBJECT_ID/likes
Paramas = dictionary with comment ,for like option use empty dictionary
HttpMethod should be POST
you should get response = true if the LIKE request is successful.
There are a bunch of tutorials online about how to use xmlparsers or what not to bring an entire twitter feed into a UITableView. Thats not what I need. I only want ONE tweet. The most recent twitter update.
So, would some of you geniuses please show me in detail how to get my last (most recent) TWEET into an NSString in my iPhone app?
In short: exactly the same as all those tutorials that you've read except you pass the count parameter to the statuses/user_timeline REST method.
Ohh, this is complicated, not so easy, I show you the steps:
Make the request to the api (synchronous or asynchonous)
Handle the Authentication Challenge for authenticated request
Get the data, call the parse method of the parser
Handle the delegation methods of the nsxmlparser
Manually handle the DidStartElement, DidFoundCharacters, DidEndElement to get the first status you want, assign the string value to a variable when it founds the characters.
That's all you need to do ;)
Good luck.
I'm looking for a simple example of how to send a Tweet from an iphone app. I've seen some very complex methods, but it can't be that difficult. I have registered the app with twitter, so I have the key & secret. Just need to know where to put these so I can send a status update and have it say "sent from MyApp".

If you're using MGTwitterEngine you need to call the following method on your instance of MGTwitterEngine:
- (void)setClientName:(NSString *)name version:(NSString *)version URL:(NSString *)url token:(NSString *)token;
You might want to check out the version that explicitly supports OAuth.
MGTwitterEngine! Don't reinvent the wheel. Use either this (it's fantastically easy to use) or the CocoaRest library.
