Load Custom UiTableView as a ChildViewController in custom TabBarNavigationController - ios

Question

I'm trying to incorporate XLMailBox, Custom ViewController as a parent viewController that can switch between different childViewController using a TabBar.
I'm loading a Custom UITableViewController
called SwipeTableViewController as a childViewController within a parent viewController
I use this code to load the ParentViewController in AppDelegate as RootViewController:
#implementation SwipeTableAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
SwipeTableViewController * child_1 = [[SwipeTableViewController alloc] initWithStyle:UITableViewStylePlain];
NSArray * childViewControllers = #[child_1];
XLSwipeContainerController * containerController = [[XLSwipeContainerController alloc] initWithViewControllers:childViewControllers];
self.window.rootViewController = [[UINavigationController alloc] initWithRootViewController:containerController];
return YES;
}
The SwipeTableViewController loads the table view as follows:
- (void)viewDidLoad
{
[super viewDidLoad];
patternImages = [NSMutableArray arrayWithObjects:#"neon-autumn.gif", #"alchemy.jpg", #"white-wood.jpg", #"green-goblin.png", #"subway-lines.png", #"canvas-orange.jpg", #"kiwis.png", #"cuadros.png", #"hodgepodge.png", #"naranjas.png", #"bunting-flag.png", nil];
self.title = #"Rounds";
_patients = [RND_PatientDB loadScaryBugDocs];
[self.tableView registerClass:[CustomTableViewCell class] forCellReuseIdentifier:#"Cell"];
NSLog(#"FirstViewController - viewDidLoad");
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
target:self action:#selector(addTapped:)];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"Cell";
CustomTableViewCell *cell = (CustomTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
RND_Patient *patients = [self.patients objectAtIndex:indexPath.row];
cell.patternImageView.image = [UIImage imageNamed:[patternImages objectAtIndex:indexPath.row]];
cell.patternLabel.text = patients.data.ptName;
cell.ptDesc.text = patients.data.ptDesc;
cell.ptNumber.text = patients.data.ptNumber;
if (patients.data.completed == 1){
cell.backgroundColor = [UIColor greenColor];
}
return cell;
}
It then configures the cell using the CustomTableViewCell class and populates with data from RND_Patients mutablearray which it loads initially.
Now my problem is that when I load the SwipeTableViewController as a childViewController, the cells are empty and are not populated with data.
When I load directly the SwipeTableViewController as part of the RootViewController without using the XLMailBox custom navigation controller, the table view loads just fine and has the appropriate cells and the appropriate data.
I do not understand the discrepancy between these two views. All my code seems correct, but in my first example, the CustomTableViewCell does not load and in the second it loads. Any ideas on how can I fix this?
