No code execution when the method sendAsynchronousRequest of NSRLConnection fails

Question

I've implemented this operation:

   [NSURLConnection sendAsynchronousRequest:theRequest queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) {
                if (connectionError) {
                    NSLog(@"Error %@ | contaShow %i",connectionError.description,_contaShow);
                    //OPERATIONS in case of error
                } else {
                   //OPERATIONS in case of success

Sometime, if occurs a connection error (ex. lost connection) I want execute the code inside the if block. With debug I can see that the code lines are called, but aren't executed!!!

Somebody can tell me why?!?

Thanks...

If the connection returns an error code (e.g. 404), you'll likely go into the success case, because you need to also check the value of ((NSHTTPURLResponse *)response).statusCode to make sure it is 200.

Beyond that, make sure you're using a debug build. Otherwise, the debugger may lie to you about what lines of code are executing.
