Question

I’m trying to fetch information from a JSON web service with this code, using SBJsonParser API:

 SBJsonParser *parser = [[SBJsonParser alloc] init];

// Prepare URL request to download statuses from Twitter
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://twitter.com/statuses/public_timeline.json"]];

// Perform request and get JSON back as a NSData object
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

// Get JSON as a NSString from NSData response
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];

But I need to add to the web service URL two parameters, user and password, with their values, so the URL will be “http://twitter.com/statuses/public_timeline.json?user=name&password=test”. I have searched information about APIs to do it but I wasn’t successful.

Many thanks for your help.

I assume you have the values in variables, correct? If so, just use the stringWithFormat: method of NSString.

Replace:

@"http://twitter.com/statuses/public_timeline.json"

With:

[NSString stringWithFormat:@"http://twitter.com/statuses/public_timeline.json?user=%@&password=%@", user, password]
