I have an iPhone app based on a tabBar and tableViews. I want the user to be able to click on one tab and access options for filtering the data in the initial tableView.

The problem I’m having is that while the user is selecting filter criteria, I want the main table (not visible) to update. The reason this is important is that I want to show how many cells are still in the table as it is being filtered in the navigation bar.

Currently, the method for filtering the main table (-handleFilter) is called in the viewWillAppear method of my rootViewController class. How can I call this method from my “searchOptions” class?

Thanks for the help!

    It sounds like you’re conflating too much between your model and your controllers (assuming you’re following the MVC design pattern). The other controllers besides the main table should be able to query the model themselves to display the count information without asking the main table controller.

    I could be misunderstanding something though, a little more information on what data you’re using and how it’s being filtered in the controllers attached to the other tab bar items would help.
