how to call dealloc method
<p>I am new to iPhone development.
I am calling one viewController on my button click event. But when I come back, my <code>-dealloc</code> method is not called. Here is my code of button click event:</p>

<pre><code>-(IBAction)btnAddPressed:(id)sender
{
    FriendsTableListViewController *viewController = [[FriendsTableListViewController alloc] initWithNibName:@"FriendsTableListViewController" bundle:nil];
    [self.navigationController pushViewController:viewController animated:YES];
    [viewController release];
}
</code></pre>

<p>Here is my dealloc method of viewController where i was after clicked on button:</p>

<pre><code>-(void)dealloc{
    [super dealloc];
}
</code></pre>

<p>I don't know why dealloc method is not working properly. Please help me. Thanking you...</p>
