iphone开发 cookie处理
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.
1 NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
2 NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
Then, implement a delegate method.
1 - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
2 {
3 NSHTTPURLResponse *HTTPResponse = (NSHTTPURLResponse *)response;
4 NSDictionary *fields = [HTTPResponse allHeaderFields];
5 NSString *cookie = [fields valueForKey:"Set-Cookie"]; // It is your cookie
6 }
Retain or copy the cookie string. When you want to perform another request, add it to your HTTP header of your NSURLRequest instance.
1 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
2 [request addValue:cookie forHTTPHeaderField:"Cookie"];
ps：
You don't need to do this, NSURLConnection automatically stores and sends cookies unless you explicitly tell it not to. – benzado Apr 20 '10 at 15:33
Even though this shouldn't be necessary fixed a suspected bug in iOS 4.2GM – crackity_jones Nov 12 '10 at 0:09

代码调试通过，具体可以参看Xcode Document
-(void)writeCookie{
