Force reload of UITableView - objective-c

I have a tabBar application. There are 2 UIViewControllers A and B. UIViewController B has UITableView. I call method in A UIViewController from B UIViewController: [b someMethod:someObject];

Here is code:

-(void) someMethod:someObject
{
  [tableViewDataArray addObject: someObject];
  [tableView reloadData];
}

But UITableView doesn't reload until I switch UIViewController to B; How to reload it without switching? If this possible

your best solution is to put a button on the toolbar for adding and refreshing and make a function called add() and connect it to the button. and inside there you do : 

-(void) add:someObject
{
[tableViewDataArray addObject: someObject];
[tableView reloadData];
}

I was having a similar issue and this actually worked, this should help : How to Reload a UITableView While I am Looking at It

UITabBarController doesn't load all its tabs' views until they are actually needed, so your table view probably doesn't even exist (i.e. is nil) before you switch to the tab that contains it.

While you could force the view controller to load its view hierarchy by accessing its view property, I wouldn't recommend it. What's the point of reloading an invisible table view anyway?
