I have added tabBarController in my project.There is one tabBarItem called ContactsViewController which has tableView with customCell.When I click on the tableViewRow it takes me to next view.then I click someother tabBarItem and again click ContactsViewController i am getting error as UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath.What is wrong with my code?

-(void) tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
    if (tabBarController.selectedIndex == 0) {

    }
    else if (tabBarController.selectedIndex == 1) {

 UINavigationController *requiredNavigationController = [tabBarController.viewControllers objectAtIndex:1];
        [requiredNavigationController popToRootViewControllerAnimated:YES];

    }

after i added above method in Appdelegate.m i am getting excepion

@sugan.s Read [this post](http://stackoverflow.com/a/5909287/468724) and it will clear that using `0` is absolutely fine. — Inder Kumar Rathore, Mar 12 '13 at 05:27

Table is not getting your custom cell.Check your ContactCustom cell.xib and add your ContactCustom as the class of the cell.
enter image description here

add your custom class name instead of "DeckListCell".

try this:

if (tableView ==tableview1) {
            ContactCustom *cell1=(ContactCustom *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) 
    { 
       NSArray *nib;
       nib= [[NSBundle mainBundle] loadNibNamed:@"ContactCustom" owner:self  options:nil];
        for (id oneObject in nib) if ([oneObject isKindOfClass:[ContactCustom class]])
                cell = (ContactCustom *)oneObject;

       // configure your cell.
    }
  return cell;
 }
