Does UITableViewController equal to UITableViewDataSource, UITableViewDelegate

Question

Could we use UITableViewDataSource, UITableViewDelegate totally replace UITableViewController, for example, is there difference between these two code lines?

@interface ShareViewController : UITableViewController
@interface ShareViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>

Answer 1

There is a BIG difference between these two lines of code. This

@interface ShareViewController : UITableViewController

means that your ShareViewController inherits from UITableViewController, so it provides, for example, an UITableView as main view. This

@interface ShareViewController : UIViewController<UITableViewDataSource, UITableViewDelegate>

means that your ShareViewController is a classic UIViewController (inherits from UIViewController) and simply implements protocols to manage table views.
