Do it like this
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeIndeterminate;
hud.labelText = @"Loading..";
dispatch_queue_t dispatchQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(dispatchQueue, ^(void)
{
[self information];
dispatch_sync(dispatch_get_main_queue(), ^{
[hud hide:YES];
});
});
