Release or abstract?

Question

Should I use release or autorelease for varSecondViewController?

-(IBAction)takeNextStep: (id) sender
{
    SecondViewController *varSecondViewController = [[SecondViewController alloc]     
       initWithNibName:@"SecondViewController" bundle:nil];
    [self.navigationController pushViewController:varSecondViewController animated:YES];
    [varSecondViewController release];
}

Answer 1

My rule:

If you intend to use it, and then no longer need to reference it, release it,

If you transfer it back to the caller (i.e. return it), run it.

Answer 2

autorelease - release, , , . , , , - . , . release.

Answer 3

In this case, it releasemakes the most sense.
