Question

What is the best way to check which request is which inside the delegate method:

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{

}

Right now I have a NSURLConnection that I set to the NSURLConnection before making a request and inside didReceiveResponse I do:

if (self.tempConnection == connection)

however there is a possiblity this won’t work for race conditions. Is there a better way to do this?

There is a better way in OS5. Forget about all those bothersome delegate messages. Let the connection build the data for you, and put your finished code right in line with your start code:

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.site.com"]];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];

[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
{
    NSHTTPURLResponse* httpResponse = (NSHTTPURLResponse*)response;
    NSLog(@"got response %d, data = %@, error = %@", [httpResponse statusCode], data, error);
}];
