1. The dao object is never released
2. It’s initialized in the wrong place

The first one is easy to fix. Just add [dao release] in the dealloc method. The second one is kind of a neat mistake. Since viewWillAppear is called every time a view is displayed, we actually allocate dao more times than we release it. Putting the initialization in viewDidLoad is the way to go since that method is called only once when the view is initialized.

I updated the final source code to include the fixes.

I have a question on this implemented code. I’ve been trying to work through it awhile and can’t quite figure it out.

So in my version of this I am pushing the Tab View in the exact same way as described here, however, each of my individual tab views are actually Table Views. This looks and displays great and works fantastic for sorting.

The problem I’ve run into is when I drill down off of that Table view, the Navbar gives me serious problems, it always stays on top, even when I pop Modal views. I’ve tried absolutely everything I can think of to hide the Navbar when drilling down but the Tab Bar’s Navbar always remains on top.

Using the example above, this would be like popping a modal view if you clicked on the Batman image. If you did this, the top of that popped modal view would be overlapped by the “Dark Night” navbar given in the example picture.

I have a feeling I need to call my Modal View pop ups from somewhere else, outside of the Tab Controller’s subviews. Anyone have any idea?

Thank you.

- (void)viewWillAppear:(BOOL)animated {
[dao release]; /*HERE*/
dao = [[DvdLibraryDao alloc] initWithLibraryName:@”TestData”];
self.title = @”My DVD Library”;
[self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES];
}

Just want to say this is a killer bit of code that made my morning! The explanations are clear and to the point, and you don’t meander about with info that’s not useful… Perfect!

Thanks again,
Thom
