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 layoutFeedbackLoopDebugger3.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 vc 和 navigationer 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
_resetLayoutEngineHostConstraints4.2 view layoutSubviews
willSendLayoutSubviewsToView:
layoutSubviews
didSendLayoutSubviewsToView4.3 循环 4.1和4.2 一直到直系的子 View 完成布局
_wantsReapplicationOfAutoLayoutWithLayoutDirtyOnEntry
_updateConstraintsAsNecessaryAndApplyLayoutFromEngine4.4 更新 SafeArea
_updateSafeAreaInsets
5.结束布局前
5.1 通知 vc
willSendViewDidLayoutSubviewsToViewControllerOfViewvc 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;
@end5.2 AutoLayout 相关逻辑
_wantsReapplicationOfAutoLayoutWithLayoutDirtyOnEntry:
_updateConstraintsAsNecessaryAndApplyLayoutFromEngine5.3 转场动画相关（UIPresentationController）
containerViewDidLayoutSubviews5.4 Debug 相关
_toolsDebugAlignmentRects
_alignmentDebuggingOverlayCreateIfNecessary:
_toolsDebugColorViewBounds
_colorViewBoundsOverlayCreateIfNecessary:
_toolsDebugShouldDetectClippedViews5.5 圆角相关的逻辑
detectAndHandleClippedView6.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
