UIRefreshControl not showing indicator or title?

Question

I want to implement Pull To Refresh to my UITableViewController by using UIRefreshControl. Here what i tried so far.

 - (void)viewDidLoad
    {
     .....
     ////********* Pull to refresh ************/
        UIRefreshControl *refresh = [[UIRefreshControl alloc] init];
        refresh.attributedTitle = [[NSAttributedString alloc] initWithString:@"Pull to Refresh"];
        refresh.tintColor = [UIColor magentaColor];
     //   [self.tableView addSubview:refresh];
// [self.refreshControl setEnabled:YES];
        [refresh addTarget:self action:@selector(pullToRefresh:) forControlEvents:UIControlEventValueChanged];
        self.refreshControl = refresh;

    }
    -(void)pullToRefresh:(UIRefreshControl *)refresh {
         [refresh beginRefreshing];
        refresh.attributedTitle = [[NSAttributedString alloc] initWithString:@"Refreshing.."];
        [self loadRecentActivities];
    }

But when i pull the tableview neither activity indicator nor title is visible, however pullToRefresh is called and table refreshed.My app supports iOS7.0+. What i'm missing? Any help would be appreciated?

Edit: I'v tried with [self.refreshControl setEnabled:YES]; and [self.refreshControl setEnabled:YES]; as mentioned in my edited code, but still no luck. This is how my tableview looks like when i pull it to refresh-

Final Solution: For table view background i was using

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"background.png"]];
self.tableView.backgroundView = imageView;

Refresh indicator and title was hidden behind the self.tableView.backgroundView instead use

[self.tableView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"background.png"]]];

and it solves my problem. also many thanks to Balram Tiwari please see his answer if you still have problem.

Just add self.tableView.backgroundView.layer.zPosition -= 1; under the initialisation code for refreshControl.
