Installation

Carthage

github "naru-jpn/View2ViewTransition"

CocoaPods

pod 'View2ViewTransition'

Usage

Create TransitionController and implement presentation

// Create TransitionController
var transitionController: TransitionController = TransitionController()

// Present view controller with transition delegate
let presentedViewController: PresentedViewController = PresentedViewController()
presentedViewController.transitioningDelegate = transitionController

transitionController.present(viewController: presentedViewController, on: self, attached: presentedViewController, completion: nil)

(also supports push)

// Set transitionController as a navigation controller delegate and push.
let presentedViewController: PresentedViewController = PresentedViewController()

if let navigationController = self.navigationController {
   navigationController.delegate = transitionController
   transitionController.push(viewController: presentedViewController, on: self, attached: presentedViewController)
}

Presenting viewController conforms View2ViewTransitionPresenting

func initialFrame(userInfo: [String: AnyObject]?, isPresenting: Bool) -> CGRect
func initialView(userInfo: [String: AnyObject]?, isPresenting: Bool) -> UIView
func prepereInitialView(userInfo: [String: AnyObject]?, isPresenting: Bool) -> Void // (optional)

Presented viewController conforms View2ViewTransitionPresented

func destinationFrame(userInfo: [String: AnyObject]?, isPresenting: Bool) -> CGRect
func destinationView(userInfo: [String: AnyObject]?, isPresenting: Bool) -> UIView
func prepareDestinationView(userInfo: [String: AnyObject]?, isPresenting: Bool) -> Void // (optional)

Use UserInfo

You can set userInfo to notify indexPath or share resource etc.

transitionController.userInfo = ["key": "value", ...]

Modify Animation Parameters

Animate with custom animation parameters.

// For present
transitionController.presentAnimationController.usingSpringWithDamping = 0.7
transitionController.presentAnimationController.initialSpringVelocity = 0.0
transitionController.presentAnimationController.animationOptions = [.CurveEaseInOut]

// For dismiss
transitionController.dismissAnimationController.usingSpringWithDamping = 0.7
transitionController.dismissAnimationController.initialSpringVelocity = 0.0
transitionController.dismissAnimationController.animationOptions = [.CurveEaseInOut]

Debug Mode

If you have hierarchical view controllers (navigation controllers) in app, viewController to conform protocol is not intuitive. View2ViewTransition prints some information in debug mode.

let transitionController = TransitionController()
// ...
transitionController.debuging = true
