UINavigation Controller The UINavigationController class implements a specialized view controller that manages the navigation of hierarchical content.

UINavigation Controller

The views of a navigation controller

UINavigationController Property

you do not have to pop view controllers off the stack programmatically. Instead, the navigation controller provides a back button on the navigation bar, that when tapped, pops the topmost view controller automatically UINavigationController Stack

UINavigationBar Property

[ [ [ UIBarButtonItem alloc ] [ [ [ UIBarButtonItem alloc ] initWithImage:[UIImage self.navigationItem.prompt = [NSString click a button now"];

UINavigationBar Property 보통 뷰 컨트롤러의 init 메소드에서 설정 UINavigationItem - 내부클래스 타이틀 설정 self.title Box”;

How To Programming?

UINavigation Controller 생성 NIB

ToolBar 추가

이미지와 텍스트 버튼 NSMutableArray *buttons = [[NSMutbleArray alloc] init]; UIBarButtonItem *buttonImage = [[UIBarButtonItem alloc] initWithImage: [UIImage style: UIBarButtonItemStylePlain target:self ]; initWithCustomView:myView];... initWithBarButtonSystemItem:UIBarButtonSystemItemBookmarks... UIBarButtonItem.h 참고

ToolBar 추가 이미지와 텍스트 버튼 UIBarButtonItem.h 참고 [buttons addObject: buttonImage]; [buttons addObject: buttonText]; [buttons addObject: myBookmarks]; UIToolbar *toolbar = [[UIToolbar alloc] init]; [toolbar setItems: buttons animated: YES]; self.navigationItem.titleView = toolbar; [toolbar sizeToFit]; toolbar.barStyle = UIBarStyleDefault; UIBarStyleDefault UIBarStyleBlackOpaque UIBarStyleBlackTranslucent

Modifying the Navigation Stack

pushViewController:animated: Display the next level of hierarchical data. popViewControllerAnimated: Back up one level in the hierarchy. setViewControllers:animated: Restore the navigation stack to a previous state. popToRootViewControllerAnimated: Return the user to the root view controller. popToViewController:animated: Back up an arbitrary number of levels in the hierarchy.

The UITabBarController class implements a specialized view controller that manages a radio-style selection interface. This class is not intended for subclassing. Instead, you use instances of it as-is to present an interface that allows the user to choose between different modes of operation. This tab bar interface displays tabs at the bottom of the window for selecting between the different modes and for displaying the views for that mode.
