Question

I have following code in a subclass of UITableViewController. Under iOS 5.1 it works fine, but under iOS 6, self.tableView is nil (both in simulator and on real device). Am I doing it wrong? Why isn’t the view set straight away after the init?

- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];

    if (self) 
    {
        UIView * bck = [[UIView alloc] init];
        [bck setBackgroundColor:[UIColor whiteColor]];
        self.tableView.backgroundView = bck;
        [bck release];
    }

    return self;
}

EDIT:

I’ve nailed down the problem:

I’ve got class

AccountsListViewController_iPad

which is subclass of

AccountsListViewController : UITableViewController

AccountsListViewController has it’s tableView & view loaded after init (as I would expect). AccountsListViewController_iPad on the other hand has it’s view and tableView equal to nil. I’ve removed everything from AccountsListViewController_iPad so now it looks as follows:

.h
#import <UIKit/UIKit.h>
#import "AccountsListViewController.h"
@interface AccountsListViewController_iPad : AccountsListViewController
@end

.m
#import "AccountsListViewController_iPad.h"
@implementation AccountsListViewController_iPad
@end

And still it’s view is nil. In my opinion, it should behave exactly the same as its superclass, but it doesn’t.

Answer 1

Alright, I’ve worked it out:

There was AccountsListViewController_iPad class and associated AccountsListViewController_iPad.xib file. Xib, despite not being loaded anywhere in the code and file owner in xib not being AccountsListViewController_iPad, was still being loaded. For some reason, the table view in xib was set to property ‘table’ in file owner (which didn’t exist) and hence view and tableView were nil.

I still don’t know why the xib was loaded or why it issue exist happen under iOS 5.x
