Answer 1

You can use the NSURLConnection class to perform a HTTP request to login the website, and retrieve the cookie. To perform a request, just create an instance of NSURLConnection and assign a delegate object to it.

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];

Then, implement a delegate method.

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *)response;
    NSDictionary *fields = [httpResponse allHeaderFields];
    NSString *cookie = [fields valueForKey:@"Set-Cookie"]; // It is your cookie
}

Retain or copy the cookie string. When you want to perform another request, add it to your HTTP header of your NSURLRequest instance.

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
[request addValue:cookie forHTTPHeaderField:@"Cookie"];
