Recently modified my app to include a tab view controller. I'm now unable to load all of the categories that are in my SQLite database when the app launches and goes to the Categories table view nav controller on app load (CategoriesViewController). There are 6 category names that it should display; sometimes the app displays 0 rows, other times it displays 4. Modifying the XML file that this pulls data from, I got it to pull 6 categories (after a few times of 0 and fast execution speed). Leads me to think this has to do with timing of execution vs. time until the table view is loaded with data. Any ideas on what I need to change to get CategoriesViewController to display the table only after all data is read? Here's the code; please let me know if there's anything else that you'd need to see. Thanks!
