My second level detail controller is not showing the initWithObjects in my array in the viewDidLoad method

Question

I am creating a Two Level table view. And the second view is supposed to have the list of the movies I have listed below in my viewDidLoad method, but it is not showing.(You can see my screen shots attached)Does anyone know which file where I can look to see why it is not showing? The code below is from my DisclosureButtonController.m file which is to display this information after I hit the Disclosure Buttons instance on the First Level screen.

Regards,

#import "LWWDisclosureButtonController.h"
#import "LWWAppDelegate.h"
#import "LWWDisclosureDetailController.h"

@interface LWWDisclosureButtonController ()
@property (strong, nonatomic) LWWDisclosureDetailController *childController;
@end

@implementation LWWDisclosureButtonController

@synthesize list;
@synthesize childController;

//- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
//{
//  self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
//if (self) {
    // Custom initialization
//}
//return self;
//}

 self.list = array;
// Do any additional setup after loading the view.
}

- (void)viewDidUnload
{
[super viewDidUnload];
self.list = nil;
self.childController = nil;
// Release any retained subviews of the main view.

Answer 1

Why not start the array with the VC instead of after the VC loads? Try overriding the init method.

- (id) init {
    if((self == [super init])) {
        //load your array here and set
    }
    return self;
}

That way, on older devices, you don't have to wait after the view loads to see the array. But, however, this is my preference. I love to override init methods and create my own.

Also, for some weird reason on my SDK, I have to use NSMutableArray instead of NSArray or it won't work. Maybe you have the same issue?

Also, I've noticed NSString *selectedMovie. Instead of using just "row", use the getter indexPath.row.

Hope these suggestions helped!

Call:

[self.tableView reloadData]; (put in place of self.tableView the var or property connected to the tableView)

after the:

self.list = array;

code line in the viewDidLoad method

and put a

NSLog(@"number of rows: %d", [self.list count]);

in

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
  {
     return [list count];//
  }

to check if it is not zero.
