I have an iOS app using iOS 5 and Xcode 4.3.2 that is made up of 7 view controllers. VC1 links to VC2, VC2 can link to VC3-VC7 and each of those controllers can link to each other (think of it as a side bar navigation). If I use segues the views are repeatedly added to the stack and if a user goes back and forth it can use a large amount of memory. How can I implement this navigation where I release the previous controller? They are all small controllers so loading them takes little time/processor/memory. Can I presentViewController and then release the presentingViewController somehow? Thanks.

    If you implement a UINavigationController, you can use the push and pop view controller methods to go back and forth. popToViewController:animated: is described here, along with 3 other helpful methods.
