Question

I have a UITableViewController. When you select a cell, it calls init on a UIViewController, which programmatically creates a bunch of views and adds them to the screen. Everything here works fine.

As the user interacts with the app, the views are moved or deleted. I want to have a button where the user can “Start Over” and the UIViewController will init and draw itself like new on the screen. Basically I want the same behavior as if the user went “back” to the UITableViewController and clicked on that same item again.

I can create the button and wire it up and everything. What I need to know is how to release and re-initialize the UIViewController.

How do I do that?

Create your UIViews in UIMyViewController controller.
and use the below code for pushing your view controller in navigation stack.

-(void) buttonClcked:(id) sender
{
    //Create for pushing another view controller in navigation stack.
    UIMyViewController *myViewController = [[UIMyViewController alloc] init];
    //to push view controller in navigation stack.
    [self.navigationController pushViewController:myViewController animated:YES];

    // you could release it because now it's retained by your UINavigationController

    [myViewController release];
     myViewController = nil;
}
