    简单猜测一下,如果有错误希望大家帮忙纠正。调用栈在最下面

    1.准备

    1.1 遍历了 layer 数组。并且调用了 _layoutEngine,发了一个 performPendingChangeNotifications

    1.2 和 window 通讯

    _applyInvocationsTo:window:
    

    2.Debug 相关的逻辑

    中间有一些 UIViewLayoutFeedbackLoopDebugger 的东西

    _UIViewLayoutFeedbackLoopDebugger layoutFeedbackLoopDebugger
    

    3.正式�开始前的准备

    didEnterLayoutSublayersOfLayerForView:
    

    3.1 跑一个循环
    给每个 view 的 layoutEngine 、delegate、_hostsLayoutEngine 赋值

    for UIView._imminentLayoutSubviewsCount {
        layoutEngine = ?
        delegate = ?
        hostsLayoutEngine = ?
    }
    

    3.2 通知 vcnavigationer 一些不知道干什么(我们不关心)的事情

    // ==== vc
    _viewControllerToNotifyOnLayoutSubviews
    _lastNotifiedTraitCollection
    _canSkipTraitsAndOverlayUpdatesForViewControllerToNotifyOnLayoutResetState
    _updateTraitsIfNecessary
    ……
    

    4.真正Layout

    4.1 LayoutEngine

    猜测和 AutoLayout 有关系

    _usesLayoutEngineHostingConstraints
    _resetLayoutEngineHostConstraints
    

    4.2 view layoutSubviews

    willSendLayoutSubviewsToView:
    layoutSubviews
    didSendLayoutSubviewsToView
    

    4.3 循环 4.1和4.2 一直到直系的子 View 完成布局

    _wantsReapplicationOfAutoLayoutWithLayoutDirtyOnEntry
    _updateConstraintsAsNecessaryAndApplyLayoutFromEngine
    

    4.4 更新 SafeArea
    _updateSafeAreaInsets

    5.结束布局前

    5.1 通知 vc

    willSendViewDidLayoutSubviewsToViewControllerOfView
    

    vc 调用 viewDidLayoutSubviews

    didSendViewDidLayoutSubviewsToViewControllerOfView:
    

    vc 的 embeddedDelegate 调用 viewControllerViewDidLayoutSubviews

    @protocol _UIViewControllerContentViewEmbedding
    - (void)viewController:(id)arg1 viewDidAppear:(_Bool)arg2;
    - (void)viewController:(id)arg1 viewDidDisappear:(_Bool)arg2;
    - (void)viewController:(id)arg1 viewWillAppear:(_Bool)arg2;
    - (void)viewController:(id)arg1 viewWillDisappear:(_Bool)arg2;
    - (void)viewControllerViewDidLayoutSubviews:(id)arg1;
    - (void)viewControllerViewWillLayoutSubviews:(id)arg1;
    @end
    

    5.2 AutoLayout 相关逻辑

    _wantsReapplicationOfAutoLayoutWithLayoutDirtyOnEntry:
    _updateConstraintsAsNecessaryAndApplyLayoutFromEngine
    

    5.3 转场动画相关(UIPresentationController)

    containerViewDidLayoutSubviews
    

    5.4 Debug 相关

    _toolsDebugAlignmentRects
    _alignmentDebuggingOverlayCreateIfNecessary:
    _toolsDebugColorViewBounds
    _colorViewBoundsOverlayCreateIfNecessary:
    _toolsDebugShouldDetectClippedViews
    

    5.5 圆角相关的逻辑

    detectAndHandleClippedView
    

    6.结束布局

    6.1 根据布局时间计算这次的 layout 的 hash 值。

    _validateLayoutHashHasChangedWithLayoutTime:
    

    这里就有点奇怪了,拿到布局的时间能用来做什么?

    6.2 正式退出
    willExitLayoutSublayersOfLayerForView

    tableView 的调用栈为例
