I am new to Objective-c, I want to ask what is the different between view controller and view such as “UITableView” and “UITableViewController”?
What happen if I use UITableView instead of UITableViewController?
Thanks

You should look up the Model-View-Controller pattern in the Apple’s documentation, since it is very important for using Cocoa. Basically, the idea in Model-View-Controller is a pattern for designing your class structure. Broadly, the model is where the application’s data should be kept. The view is what controls the application’s appearance and the controller is the place where the two are assembled. (Ideally, the view and the model classes do not even need to know about the other’s existence).
Hence, the UITableView and UITableViewController are two different classes with two different purposes. The UITableView controls the appearance of the data and the UITableViewController “controls” the view (generally by passing it the correct data for display and layout). Since this pattern shows up again and again in Cocoa programming, you should take some time to become familiar with it.
