Question

I have this method.

[self postRequestWithURL: (NSString *) postArgs:(NSDictionary *) headerArgs: (NSDictionary *) ];

How can I correctly call this method?

the url is: http://www.google.com/reader/api/0/edit-tag?

the post args are: "a=user/-/state/com.google/read&ac=edit-tags&s=feed/%@&i=%@&T=%@", entry.link, entry.identifier, tokenString

and header are:

NSString *authHeader = [NSString stringWithFormat:@"GoogleLogin %@", authString];
[thttpReq addValue:authHeader forHTTPHeaderField:@"Authorization"];

[thttpReq addValue:@"Content-Type" forHTTPHeaderField:@"application/x-www-form-urlencoded"];

Can sompne help me to insert postArgs and HeaderArgs in a NSDictionary?
Thanks
Paolo

Try something like this:

NSDictionary *postArgs = [NSDictionary dictionaryWithObjectsAndKeys: 
                            @"user/-/state/com.google/read", @"a",
                            @"edit-tags", @"ac",
                            [NSString stringWithFormat: @"feed/%@", entry.link], @"s",
                            [NSString stringWithFormat: @"%@", entry.identifier], @"i",
                            [NSString stringWithFormat: @"%@", tokenString], @"T",
                            nil];

NSDictionary *headerArgs = [NSDictionary dictionaryWithObjectsAndKeys: 
                             [NSString stringWithFormat: @"GoogleLogin %@", authString], @"Authorization",
                             @"application/x-www-form-urlencoded", @"Content-Type"
                             nil];

[self postRequestWithURL: @"http://www.google.com/reader/api/0/edit-tag"
                postArgs: postArgs
              headerArgs: headerArgs];

Note that the list after dictionaryWithObjectsAndKeys: contains alternations of objects and keys, separated by commas, followed by a final nil, as in the example above.

FWIW, the dictionaries here are autoreleased, so you don’t have to release them explicitly.
