I have an application that uses a UITabBarController, and inside each tab I have Navigation Controllers.
I would like to make one of the views reload itself after an action happens in another view, so that when the user goes back to that view – it’s updated.
Is it possible?
The simplest way to accomplish this is to put your loading code into viewWillAppear: instead of
viewDidLoad. WhileviewDidLoadmay only get called once, when your view is initialized,viewWillAppear:is called any time your view controller is about to be presented, whether it be in the tab bar, in a navigation controller, etc., which gives you a nice hook to implement loading and layout functionality.
