UITableViewController中的View属性和TableView属性有什么区别？

Question

After doing some research in apple documentation here's what I found.

In UIViewController , the view property

@property(nonatomic, retain) UIView *view

means the view that the controller manages.

and

In UITableViewController , the tableView property

@property(nonatomic, retain) UITableView *tableView

means the tableView that the controller manages.

Since UITableViewController is the subclass of UIViewController , it will inherit the view property. So when I'm writing codes in UITableViewController subclass file, there's these 2 properties that always confuses me and I'm not sure when to use it. Please explain. Thanks.

Answer 1

For a UITableViewController , the tableView and view properties are the same.

Use the tableView property in your table view controller when you need to access the table view and make use of various UITableView properties and methods. Or even if you need plain old UIView methods.

It's fine to use the view property in cases where you only need UIView properties and methods. It's really a matter of taste which property to use in this case.

Answer 2

In case of UItableViewController both are same but different in you have UITableView in the UIViewController then view property will refer to UIViewController and tableview will refer to UITableView . To avoid confusion always use tableview in case of UITableViewController
