I\'m using this code to pull a simple JSON feed from a server:
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.
try to add some rubbish at the end of your URL (for example, timestamp)
kDataUrl = [NSString stringWithFormat:@"%@?%f", kDataUrl, [NSDate timeIntervalSinceReferenceDate]];
In this case, you would request fresh data every time. That works for me))
