Customizing the More menu on a Tab bar

Question

I am using a tab bar (UITabBarController) on my app and I wish to customize the appearance of the table that appears when you click the more button. I have worked out how to

Answer 1

I followed Ian's implementation to customize the More menu, but I was having a problem retaining the customizations after a memory warning. didReceiveMemoryWarning seems to destroy the UITableView, and when it is regenerated it gets its old dataSource back. Here's my solution:

I replace viewDidLoad on the CustomTabBarController with this:

- (void)viewDidLoad {
    [super viewDidLoad];
    UINavigationController* moreController = self.moreNavigationController;
    if ([moreController.topViewController.view isKindOfClass:[UITableView class]]) {
        moreController.delegate = self;
        self.moreControllerClass = [moreController.topViewController class];
        UITableView* view = (UITableView*) moreController.topViewController.view;
        self.newDataSource = [[[MoreDataSource alloc] initWithDataSource:view.dataSource] autorelease];
    }
}

As you can see, I added a few properties for storing things I needed. Those have to be added to the header and synthesized. I also made CustomTabBarController a UINavigationControllerDelegate in the header. Here's the delegate function I added:

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    if ([viewController isKindOfClass:self.moreControllerClass]) {
        UIView* view = self.moreNavigationController.topViewController.view;
        if ([view isKindOfClass:[UITableView class]]) {
            UITableView* tview = (UITableView*) view;
            tview.dataSource = self.newDataSource;
            tview.rowHeight = 81.0;
        }
    }
}

This way I make sure my custom data source is always used, because I set it that way just prior to showing the UIMoreListController, every time it's shown.
