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.
Besides, are there are any other methods to get the header informatino?
Thank you very much.

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.
