Custom interactive view controller transition from one view to another view

by iOS Example

View2ViewTransition

Simple framework for custom interactive viewController transition from one view to another view.

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
