Good day,
I am having a little bit of a problem. I want to track user behavior for an app. The app has a tab bar with 5 tabs. Every time a user switches tabs, I'd like to know about it. That's all I want to do.
Which method should I use here?
viewWillAppear/viewDidAppear are not getting called.
A UINavigationController actually puts this UITabBar as the UINavigationController's root view (did I describe that right?). To be very clear, the user launches the app. There are several buttons. If you press one of them, you are taken to that UITabBar with its 5 associated tabs. (In the UITabBar there is a UINavigationBar that will take you to back to the home screen.). How do I get notified when the user presses tab1, tab2, tab3, tab4, tab5--no matter which order or how many times these tabs are pressed?
Do I need a UINavigationController delegate to be implemented? If so, I'm not sure where to put that code. Or is there something simpler?
Thanks!
Look at the UITabBarControllerDelegate protocol. Set your tabBarController's delegate to self (most likely) and implement tabBarController:didSelectViewController:.
