Answer 1

All View Controllers associated with a Tab Bar Controller are retained by the tab bar controller, but if you're using intense amounts of memory, you can release objects or resources used by your view controller when viewWillDisappear: or viewDidDisappear: gets called. And recreate / reallocate those memory hogging objects when viewWillAppear: or viewDidAppear: get called when the user clicks it into view again.
