I have a TabBarController, with three views, one of which is the settings view. When I go to the settings page, then come out of the app and go back in, I need the view to refresh. Is that possible?

It depends on what you want to refresh, and what your setting looks like?
If your setting view has a done or save button, you can put the refresh code there,
[someController.theTable reloadData]for example.Another way is to put the refresh code inside
viewWillAppear:in the view that you want to refresh, info can be found here:http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html#//apple_ref/occ/cl/UIViewController
