UIRefreshControl Stuck After Switching Tabs in UITabBarController with UIViewControler and UITableView

Question

My UIRefreshControl is stuck after switching tabs, It happenes only on the first tab. Inside TabBar I have 2 tabs with UIViewControler inside which I have UITableView.

I have tried all solutions suggested HERE and none worked for me.

Below is what I am am doing.

- (void)viewDidLoad {
[super viewDidLoad];

data = [[NSMutableArray alloc] initWithArray:[[DataCache sharedCache] getData]];

[self addNavBar];
[self addDataTable];

//for refreshing the table data
UITableViewController *tableViewController = [[UITableViewController alloc] init];
tableViewController.tableView = dataTable;
refreshControl = [[UIRefreshControl alloc] init];
refreshControl.backgroundColor = [UIColor purpleColor];
refreshControl.tintColor = [UIColor whiteColor];
[refreshControl addTarget:self
                   action:@selector(refresh)
         forControlEvents:UIControlEventValueChanged];
[dataTable addSubview:refreshControl];
tableViewController.refreshControl = refreshControl;
}


- (void)refresh {
[self loadSentData];
data = [[NSMutableArray alloc] initWithArray:[[DataCache sharedCache] getSentData]];
[self performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO];
}

- (void)reloadData{
[dataTable reloadData];
[refreshControl endRefreshing];
}

Since this question has been viewed hundreds of time. Adding my solution here might help someone else.

In my case, it was due to refreshControl. you need separate refreshControl for both the views. I ended up creating refreshControlFirstView and refreshControlSecondView and that resolved the issues.
