 4 | # DAExpandAnimation
 5 | A custom modal transition that presents a controller with an expanding effect while sliding out the presenter remnants.
 6 | # Screenshot
 7 | ![DAExpandAnimation](https://raw.githubusercontent.com/ifitdoesntwork/DAExpandAnimation/master/Example/screencapture.gif)
 8 | # Installation
 9 | Simply copy the `Sources/DAExpandAnimation/DAExpandAnimation.swift` file into your project.
10 | ### Swift Package Manager
11 | DAExpandAnimation is also available through [Swift Package Manager](https://github.com/apple/swift-package-manager/).
12 | ```swift
13 | .package(url: "https://github.com/ifitdoesntwork/DAExpandAnimation.git", from: "1.0.0")
14 | ```
15 | # Usage
16 | Try the example project!
17 | 
18 | Have your view controller conform to UIViewControllerTransitioningDelegate. Optionally set the `collapsedViewFrame`, the `expandedViewFrame`, the `slidingPart` and the `animationDuration`.
19 | ```swift
20 | private let animationController = DAExpandAnimation()
21 | 
22 | override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
23 |     guard let selectedCell = sender as? UITableViewCell else {
24 |         return
25 |     }
26 |     
27 |     let toViewController = segue.destination
28 |     toViewController.transitioningDelegate = self
29 |     toViewController.modalPresentationStyle = .custom
30 |     toViewController.view.backgroundColor = selectedCell.backgroundColor
31 |     
32 |     animationController.collapsedViewFrame = {
33 |         selectedCell.frame
34 |     }
35 |     animationController.animationDuration = Constants.demoAnimationDuration()
36 | }
37 |     
38 | func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
39 |     animationController
40 | }
41 | 
42 | func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
43 |     animationController
44 | }
45 | ```
46 | # Protocols
47 | 
48 | Adopting `DAExpandAnimationPresentingViewAdapter` provides the following optional delegate methods for tailoring the presenter's UX.
49 | 
50 | ```swift
51 | /// Determines whether the animations include sliding the presenter's view apart.
52 | /// Defaults to `true`.
53 | var shouldSlideApart: Bool { get }
54 | 
55 | /// Notifies the presenter's view adapter that animations are about to occur.
56 | func animationsWillBegin(in view: UIView, presenting isPresentation: Bool)
57 | 
58 | /// Notifies the presenter's view adapter that animations are just completed.
59 | func animationsDidEnd(presenting isPresentation: Bool)
60 | ```
61 | Adopting `DAExpandAnimationPresentedViewAdapter` provides the following optional delegate methods for tailoring the presentation of a new view controller.
62 | 
63 | ```swift
64 | /// Gives the presented view adapter a chance to prepare
65 | /// the expanding `view` before the animations.
66 | func prepare(expanding view: UIView)
67 | 
68 | /// Gives the presented view adapter ability to change
69 | /// properties of the expanding `view` alongside the animations.
70 | func animate(expanding view: UIView)
71 | 
72 | /// Gives the presented view adapter ability to clean the expanded `view` up
73 | /// after the animations are performed.
74 | func cleanup(expanding view: UIView)
75 | 
76 | /// Gives the presented view adapter a chance to prepare
77 | /// the collapsing `view` before the animations.
78 | func prepare(collapsing view: UIView)
79 | 
80 | /// Gives the presented view adapter ability to change
81 | /// properties of the collapsing `view` alongside the animations.
82 | func animate(collapsing view: UIView)
83 | 
84 | /// Gives the presented view adapter ability to clean the collapsed `view`
85 | /// up after the animations are performed.
86 | func cleanup(collapsing view: UIView)
