What is the best location to place the code responsible for fetching data with NSURLRequest?

As I venture into the world of developing my first iPhone app, one that fetches JSON data and displays it in UITableView, I find myself pondering a crucial question. Where is the ideal spot in my code to place the NSURLRequest?

In my quest for answers, I've delved into various samples, such as Apple's LazyTableImages, which kickstart the request within the App Delegate and appoint it as the connectionDidLoad delegate.

My own application boasts a RootController TabBar housing five distinct tabs, with each tab employing a unique UINavigationController-based class to exhibit data through a series of UITableViewControllers.

Hence, the burning question remains - given my app's intricate layout, should I embed the data loading code in the AppDelegate or its corresponding UINavigationController?

Answer №1

Instead of placing it in the view controller, consider utilizing the app delegate as this is related to data access code. Another option could be creating a custom class that handles download and data transformation tasks, along with a user-defined delegate implemented by the app delegate for reusability across different applications.
