[twitter-dev] Re: Retrieve tweets with ID greater than a passed-in ID?

[Nick Toumpelis]

Hi Greg,

I sent an email about this about a week ago because I thought that  
since_id should return all the tweets after the given ID. Apparently,   
(thanks to Matt Sanford) you also need the count parameter in the call.


As far as I can tell, your call is to the API is otherwise OK.

Hope that helps,

Nick

Greg,

It looks like the code (in jetchJSONObjectForURL) is using a shortcut 
method of grabbing data from the web with 
NSString:initWithContentsOfURL: which creates an NSString from the 
contents at a specific URL ( go figure! ).  I'm not sure if that method 
utilizes the credential store, if not you would need to expand the code 
to get the data explicitly with a NSURLConnection (Like is done in the 
updateStatus function)

You can register a set of credentials with the credential storage system 
before you make the NSURLConnection call like so:

NSURLCredential *credential =
  [NSURLCredential credentialWithUser:username
 password:password
  persistence:NSURLCredentialPersistenceForSession];

NSURLProtectionSpace *protectionSpace =
  [[NSURLProtectionSpace alloc] initWithHost:@"twitter.com"
port:0
protocol:@"http"
   realm:nil
authenticationMethod:nil];


[[NSURLCredentialStorage sharedCredentialStorage] 
setDefaultCredential:credential

forProtectionSpace:protectionSpace];

Now that the credentials are stored you are free to make your call using 
NSURLConnection (verbatim from your code):
NSData *data = [NSURLConnection sendSynchronousRequest:request 
returningResponse:&response error:&error];


Also, change this line:

NSURL *url = [NSURL URLWithString:[NSString 
stringWithFormat:@"http://%@:%@@twitter.com/statuses/update.json";, 
username, password]];

to this:

NSURL *url = [NSURL 
URLWithString:@"http://twitter.com/statuses/update.json";];

Guys, this is a little out of my realm of expertise. Any Objective-C

Greg, if no one responds soon, I'll roll my sleeves up and play around

It's just a basic library that was given as part of a class at
Stanford on iPhone development. If you want to download the source, it
can be downloaded from http://www.stanford.edu/class/cs193p/cgi-bin/index.php;
download the file called Presence4Files.zip.

The request made by the Objective-C method I'm calling is:

   
http://[username]:[passwo...@twitter.com/statuses/user_timeline/[username].json?since_id=[id]

If I leave off the since_id, it works as expected. When I specify the
since_id, it still works, but it doesn't honor the since_id in any
way.

Thanks very much,

Greg

Greg,
I'm not an Objective-C student but I'll do what I can. Can you tell me
which library you are using? Also, can you include sample code of the
request you are making (obscure your credentials of course)?

[Greg Maletic]

Hi, Doug--

Can you explain what you mean that credentials need to be "pushed
through the header?" I'm using an Objective-C library I found to
access Twitter, and the method I outlined is what this library is
doing to access password-protected accounts. If I can get some clarity
on what you mean, I might be able to rewrite some of their code to use
your technique instead.

Thanks very much,

Greg

[twitter-dev] Re: Retrieve tweets with ID greater than a passed-in ID?

[Doug Williams]

Greg,
If you want to access a user_timeline through a browser try sending a
request to:

http://twitter.com/statuses/user_timeline/[username].json
?since_id=[since_id]

where the variables denoted with [*] are replaced accordingly. You will be
prompted to input your username and password for basic authentication.

You can also try the same call through a command line with cURL:

curl -u username:password
http://twitter.com/statuses/user_timeline/[username].json?since_id=[since_id]

Does that set you on the right path? I believe what is tripping you up is
placing the credentials in the URL when they need to be pushed through the
headers.

since_id is in fact exactly what you would use. Can you give us an example
of your code and output?
