How to set a Cookie with a NSURLRequest?

Question

I\'m trying to create an login in my iPhone App.

NSURL *urlNew = [NSURL URLWithString:urlstring];
NSMutableURLRequest *theRequest = [NSMutableURLRequest req

not sure it's still relevant, but in case someone find that useful, here's how you get the cookies after making a request. You should implement the selector connectionDidFinishLoading: in the object that was specified as a delegate to NSURLConnection (self in your case):

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES];

in this connectionDidFinishLoading: selector you can access the cookies like that:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSHTTPCookieStorage * storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray * cookies = [storage cookiesForURL:connection.currentRequest.URL];
    for (NSHTTPCookie * cookie in cookies)
    {
        NSLog(@"%@=%@", cookie.name, cookie.value);
        // Here you can store the value you are interested in for example
    }
}

then later, this stored value can be used in requests like this:

[request setValue:[NSString stringWithFormat:@"%@=%@", cookieName, cookieValue] forHTTPHeaderField:@"Cookie"];

or more advanced setAllHTTPHeaderFields:, but remember to use the correct value in NSHTTPCookiePath field, see details here

also NSHTTPCookieStorage has selector -setCookies:forURL:mainDocumentURL: that can also be used to set cookies.
