Hello, I would like to get some information from a website. I have already got the HTML code of the website. However, I would like to get more header information of the website (e.g. http status code) After read the apple library, I found that there are 2 methods which can display those information. However, I can only use one of the methods (has warning), another cannot be used. The following is the code. Code: NSHTTPURLResponse *response = nil; NSError *error = nil; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *data=[[NSString alloc]initWithData:responseData encoding:NSUTF8StringEncoding]; NSDictionary *responseAlllHeaderFields = [response allHeaderFields]; // how can I convent the NSDictionary to the NSString, I cannot use the NSLog to display the information NSLog(responseAlllHeaderFields); // <-- wrong // returns the HTTP status code for the response NSInteger *responseStatusCode = [response statusCode]; // warning: initialization makes pointer from integer without a cast NSLog(@"\nThe status code is %d\n", responseStatusCode); Besides, are there are any other methods to get the header informatino? Thank you very much.
