Retrieve HTTPResponse/HTTPRequest status codes in iOS?

Question

I need to check and evaluate the HTTP Status Codes in my iPhone app. I've got an NSURLRequest object and an NSURLConnection that successfully (I think) connect to the site:

// create the request NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com/"]                         cachePolicy:NSURLRequestUseProtocolCachePolicy                     timeoutInterval:60.0]; // create the connection with the request // and start loading the data NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) {     // Create the NSMutableData that will hold     // the received data     // receivedData is declared as a method instance elsewhere     receivedData=[[NSMutableData data] retain]; } else {     // inform the user that the download could not be made } 

I got this code here: https://web.archive.org/web/20100908130503/http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/URLLoadingSystem/Tasks/UsingNSURLConnection.html

But it doesn't (as far as I can see) say anything about accessing HTTP Status codes.

How to make a connection to a site and then check the HTTP Status Codes of that connection?

Answer 1

This is how I do it:

    #pragma mark -     #pragma mark NSURLConnection Delegate Methods     - (void)connection:(NSURLConnection*)connection didReceiveResponse:(NSURLResponse*)response {          NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;          int responseStatusCode = [httpResponse statusCode];     } 

But I'm using an asynchronous NSURLConnection, so this may not help you. But I hope it does anyway!
