1. The Layer Tree

Core Animation's original name is Layer Kit

Core Animation is a compositing engine; its job is to compose different pieces of visual content on the screen, and to do so as fast as possible. The content in question is divided into individual layers stored in a hierarchy known as the layer tree. This tree forms the underpinning for all of UIKit, and for everything that you see on the screen in an iOS application.

In UIView, tasks such as rendering, layout and animation are all managed by a Core Animation class called CALayer. The only major feature of UIView that isn’t handled by CALayer is user interaction.

There are four hierarchies, each performing a different role:

// Solution 1:
//  - Use classes instead of struct
// Issue: Violate the concept of moving model to the value layer

UINavigationBar on iOS 11

NOTE This note is written based on Xcode version 9.0 beta 6 (9M214v) and its simulator binary.

iOS 11 changes UINavigationBar a lot, not just only for its large title, but also the internal view hierarchy and lay outing views are changed. This is a small note about UINavigationBar behavior on iOS 11, mainly focusing on migrating the application to iOS 11.

Lay outing views

UINavigationBar has been using manual lay outing until iOS 10, so all its content views like titleView has been directly child view of the UINavigationBar. However, since iOS 11, it is using auto layout with bunch of layout guides to lay out its content views in its own internal container view, _UINavigationBarContentView.
