Earlier than You Start
This part tells you a couple of issues you could know earlier than you get began, such because the {hardware} and software program you’ll want, the place to seek out the venture information for this ebook and extra.
Part I: Animations With SwiftUI
SwiftUI is a contemporary cross-platform declarative UI framework from Apple. SwiftUI helps all Apple platforms so, as a cool bonus, you’ll be able to apply something you be taught on this part to any of your tvOS, macOS, iPadOS and watchOS apps!
On this part, you’ll work by way of a number of totally different animations together with some lovely thumbnail zoom transitions and a modern-looking SwiftUI spinner.
On this chapter you’ll be taught in regards to the very fundamentals of SwiftUI animations after which shortly transfer onto to extra complicated and visually fascinating animations in an actual life venture.
1
You’ll proceed to be taught extra about varied view properties you’ll be able to simply animate with SwiftUI. Moreover you’ll study view transitions and gesture pushed interactive animations.
2
Part II: View Animations
This part will introduce you to the animation API of UIKit. Although easy to make use of, the UIKit animation API offers you with a number of flexibility and energy to deal with most, if not all, of your animation necessities.
Animations are seen, onscreen results that apply to the entire views, or seen objects, in your person interface. You may animate any object onscreen that finally inherits from UIView. This contains UILabel, UIImageView, UIButton and any customized courses you’ve created your self.
You’ll learn to transfer, scale and fade views. You’ll create various totally different animations to get comfy with Swift and the fundamental UIKit APIs.
3
You’ll construct on the ideas of linear animation and create extra eye-catching results utilizing spring-driven animations. Boiiing!
4
You’ll study a number of class strategies in UIKit that make it easier to animate views in or out of the display screen. These one-line API calls make transition results straightforward to realize.
5
This chapter teaches you the right way to mix strategies you’ve already realized in inventive methods to construct up even cooler animations.
6
You’ll use keyframe animations to unlock the last word achievement of a powerful UI: creating elaborate animation sequences constructed from various distinct levels.
7
Part III: Auto Structure
You’ll want a barely higher understanding of the Auto Structure paradigm than the typical iOS developer to make your animations play properly with Auto Structure. Thankfully, you’ll discover working with Auto Structure constraints in code isn’t as laborious because it sounds at first. The truth is, it’s a reasonably easy course of as soon as you’re employed by way of a couple of examples.
By the top of this part, you’ll have tamed Auto Structure and can know the right way to bend it to your will to create some actually wonderful animations.
This can be a crash course on Auto Structure in case you’re not conversant in it already; you’ll want this for the following chapter.
8
When you’ve labored by way of the venture in Chapter 8, you’ll add various animations to it and put your newfound data to good use.
9
Part IV: Layer Animations
On this part of the ebook, you’ll study animating layers as a substitute of views and the right way to use particular layers. A layer is an easy mannequin class that exposes various properties to symbolize some image-based content material. Each UIView is backed by a layer, so you’ll be able to consider layers because the lower-level behind-the-scenes class behind your content material.
By the top of this part, you’ll understand how — and when! — to animate your views, and when it’s applicable to make use of layers.
You’ll begin with the only layer animations, but in addition study debugging animations gone incorrect.
10
Right here you achieve extra management over the at the moment working animations and use delegate strategies to react to animation occasions.
11
On this chapter you mix various easy animations and run them collectively as a bunch.
12
On this chapter you learn to use `CASpringAnimation` to create highly effective and versatile spring layer animations.
13
Right here you’ll study layer keyframe animations, that are highly effective and barely totally different than view keyframe animations. There’s some particular dealing with round animating struct properties, which you’ll additionally study.
14
Draw shapes on the display screen by way of CAShapeLayer and animate its particular path property.
15
Learn to use CAGradientLayer that will help you draw and animate gradients.
16
Right here you’ll draw shapes interactively and work with some highly effective options of keyframe animations.
17
Study in regards to the little recognized however highly effective CAReplicatorLayer class.
18
Part V: View Controller Transition Animations
It’s time to learn to use UIKit and Auto Structure animation strategies within the broader context of app navigation and structure. You’ve animated a number of views and layers already, however now you’ll take a bigger-picture perspective and take into consideration animating complete view controllers!
Implementing customized view controller transitions takes some coding, however the outcomes are a number of enjoyable to take a look at and use. Regardless of which API you utilize, customized transitions are an vital animation approach that basically make an app stand out!
Learn to current view controllers by way of customized animated transitions.
19
You’ll construct upon your abilities with presenting view controllers and develop a very neat reveal transition for a navigation controller app.
20
Learn to make the reveal transition interactive: the person will have the ability to scrub backwards and forwards by way of the animated transition!
21
Part VI: Animations With UIViewPropertyAnimator
UIViewPropertyAnimator is a category that helps builders create interactive, interruptible view animations.
You can do every thing you realized thus far within the ebook by utilizing a mix of layer and look at animations, however UIViewPropertyAnimator wraps various APIs collectively conveniently in the identical class, which makes it a bit simpler to make use of.
After working by way of this part, you’ll positively be at dwelling with utilizing UIViewPropertyAnimator for every kind of animations in your apps!
Learn to create primary view animations and keyframe animations. You’ll look into utilizing customized timing that goes past the built-in easing curves.
22
On this chapter you will study utilizing animators with Auto Structure. Additional, you’ll learn to reverse animations or make additive animations for smoother adjustments alongside the best way.
23
Learn to drive your animations interactively primarily based on the person’s enter. For additional enjoyable you’ll look into each primary and keyframe animations interactivity.
24
Create customized View Controller transitions utilizing a UIViewPropertyAnimator to drive the transition animations. You’ll create each static and interactive transitions.
25
Part VII: 3D Animations
Core Animation helps you float free from the 2 dimensional world of your app’s UI. Though it isn’t a real 3D framework, Core Animation has plenty of good options that will help you place two-dimensional objects in 3D house.
Within the subsequent two chapters, you’ll learn to arrange your layers in 3D house, how to decide on the gap from the digicam to your layer and the right way to create animations in your 3D scene.
Learn to arrange your layers in 3D house, how to decide on the gap from the digicam to your layer, and the right way to create animations in your 3D scene.
26
Go additional into 3D house and study among the extra superior methods to create 3D Animations.
