Objective c 有没有了解iOS框架的路线图？

我正在寻找一张显示iOS总体框架的地图。在创建viewController时说。创建ViewController及其层次结构的确切对象是什么。还有，假设你有自我，那么超级会是什么呢？比如超级物体是什么，或者如何描绘超级物体。如果有，有人能分享吗

下面是一个例子：

而图像详细描述了实际的类层次结构，参考了直接继承；UIViewController遵循“具有”或“了解”类型设计。以下是从UIViewController.h中提取的界面顶部：

UIKIT_CLASS_AVAILABLE(2_0) @interface UIViewController : UIResponder <NSCoding, UIAppearanceContainer> {
    @package
    UIView           *_view;
    UITabBarItem     *_tabBarItem;
    UINavigationItem *_navigationItem;
    NSArray          *_toolbarItems;
    NSString         *_title;

    NSString         *_nibName;
    NSBundle         *_nibBundle;

    UIViewController *_parentViewController; // Nonretained

    UIViewController *_childModalViewController;
    UIViewController *_parentModalViewController; // Nonretained
    UIViewController *_previousRootViewController; // Nonretained    
    UIView           *_modalTransitionView;
    UIResponder      *_modalPreservedFirstResponder;
    UIResponder      *_defaultFirstResponder;
    UIDimmingView    *_dimmingView;
    UIDropShadowView *_dropShadowView;

    id                _currentAction;
    UIStoryboard     *_storyboard;
    NSArray          *_storyboardSegueTemplates;
    NSDictionary     *_externalObjectsTableForViewLoading;

    UIView           *_savedHeaderSuperview;
    UIView           *_savedFooterSuperview;

    UIBarButtonItem  *_editButtonItem;

    UISearchDisplayController *_searchDisplayController;

    UIModalTransitionStyle _modalTransitionStyle;
    UIModalPresentationStyle _modalPresentationStyle;

    UIInterfaceOrientation _lastKnownInterfaceOrientation;

    UIPopoverController*    _popoverController;
    UIView *_containerViewInSheet;
    CGSize _contentSizeForViewInPopover;
    CGSize _formSheetSize;

嗯，在我看来，ViewController只显示公共sdk（NSObject，UIResponder）。然而，如果你去查看ViewController的源代码，你可以检查使用了哪些，对吗？嗯，在我看来，ViewController只显示公共sdk（NSObject，UIResponder）。然而，若你们确实去查看ViewController的源代码，你们可以检查使用了哪些，对吗？虽然你们的评论是信息性的，但它如何帮助你们找到解决方案呢？我在Swift中的几个视图控制器中也有同样的问题。有没有关于如何更接近解决这个问题的信息？虽然你的评论提供了信息，但它如何帮助解决这个问题？我在Swift中的几个视图控制器中也有同样的问题。有没有关于如何更接近解决这一问题的信息？
