If it's possible, would you change transitionController.userInfo's type to [String: Any] or [AnyHashable: Any]? 🙇

// before
public final class TransitionController: NSObject {
    public var userInfo: [String: AnyObject]? = nil
}

// after
public final class TransitionController: NSObject {
    public var userInfo: [String: Any]? = nil // or [AnyHashable: Any]
}

I think its type should be [String: Any] or [AnyHashable: Any] in Swift3. 🤔

I've used PeekPop pod to represent a cell and found that when I go back (in UINavigationController) animation ends up with blank screen.

I want to adapt to Swift 3 this project.
Please create branch swift-3 .

"Installing View2ViewTransition (1.1.0)"
but it's not a 4.2

cancelInteractiveTransition()

let duration: Double = Double(self.duration)*Double(progress)
UIView.animateWithDuration(duration, delay: 0.0, usingSpringWithDamping: 1.0, initialSpringVelocity: 0.0, options: .CurveEaseInOut, animations: {

    self.animationController.destinationTransitionView.frame = self.animationController.destinationFrame
    self.animationController.initialTransitionView.frame = self.animationController.destinationFrame

}, completion: { _ in

    // Cancel Transition
    self.animationController.destinationTransitionView.removeFromSuperview()
    self.animationController.initialTransitionView.removeFromSuperview()

    self.animationController.destinationView.hidden = false
    self.animationController.initialView.hidden = false
    self.transitionController.presentingViewController.view.removeFromSuperview()

    self.transitionContext.completeTransition(false)
})

The line self.transitionController.presentingViewController.view.removeFromSuperview() in DismissInteractiveTransition.swift makes that the app turns black if you use the root view controller as presentingViewController and the users cancel dismiss and dismiss later.

Comment that line works in my case and I don't know if it affects in other #cases

I made a pull request with my solution #21

Hi,

I just installed this library using CocoaPods and I have this error, but I use the exactly same code provided by demo project

        transitionController.userInfo = ["destinationIndexPath": indexPath, "initialIndexPath": indexPath]
        transitionController.present(viewController: presentedViewController, on: self, attached: presentedViewController, completion: nil)

Any idea ??

Thanks.

Hello!
If UIViewController has a UINavigationController in this case in this case, does not work does not work. Why? How can fix it?

@naru-jpn can this be used with IGListKit?
Would appreciate a demo re-created using IGListKit
Specifically, getting the initialFrame and initialView from an IGListKit section is tricky.

I found crahsed bug.
write some point.

1. Show preview any image.
2. Many times swipe untile presentingView cell invisible
3. Try close
4. Crashed☠

Could you also move animation damping into Animation Controllers property?

The layer render of snapshotImage function increase the memory.

if let context: CGContext = UIGraphicsGetCurrentContext() {
	self.layer.render(in: context)
}

When I changed to

self.drawHierarchy(in: self.bounds, afterScreenUpdates: true)

It solved my problem.

Hi!

found that method:

public func present(viewController presentedViewController: UIViewController, on presentingViewController: UIViewController, attached: UIViewController, completion: (() -> Void)?) ...

is marked as unavailable.

How can we use this component in Objective-C?

I noticed that you've only implemented the transition for modal view controller presentation. It would be awesome if you could support the UINavigationControllerDelegate-based transitions. For example, instead of a new view controller being presented modally, it's pushed onto the navigation controller stack. There are two methods to support this:

• -navigationController:animationControllerForOperation:fromViewController:toViewController:
• -navigationController:interactionControllerForAnimationController:

Perhaps, TransitionController causes memory leak 😨

class ViewControlelr {
    let transitionController = TransitionController() // strong ref
}

class TransitionController {
   fileprivate(set) var presentingViewController: UIViewController? // strong ref
}

To avoid causing memory leak, TransitionController.presentingViewController should be weak var ! 🙇

Dismissing view controller shows strange behavior when multiple view controllers are presented.

1. present view controller
2. and present another view controller
3. dismiss presented view controller
4. get white screen

Found wrong view hierarchy when dismissing view controllers.

Hi!

Just figured out that I can't use cocoapods version of View2ViewTransition with my swift 3 project. Any plans to update cocoapod?

Hello! Thanks for this framework.

Please help me, I faced with this error 'present(viewController:on:attached:completion:)' is unavailable

So I'm trying to execute code

let transitionController = TransitionController()
        let imagePickerController = UIImagePickerController()
        imagePickerController.sourceType = .photoLibrary
        imagePickerController.modalPresentationStyle = .overFullScreen
        imagePickerController.transitioningDelegate = transitionController
        
        transitionController.present(viewController: imagePickerController, on: self, attached: imagePickerController, completion: nil)

How can I fix it? Thanks

Hello I made test example with CollectionView and UIViewController, but when I tried to back I see a black screen around presented controller. How can I fix it?

PresentedController code

class ChatPhotoBrowser: UIViewController {

    weak var transitionController: TransitionController!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        view.clipsToBounds = true
        edgesForExtendedLayout = []
    }


}

extension ChatPhotoBrowser: View2ViewTransitionPresented {
    
    func destinationFrame(_ userInfo: [String: AnyObject]?, isPresenting: Bool) -> CGRect {
        return view.frame
    }
    
    func destinationView(_ userInfo: [String: AnyObject]?, isPresenting: Bool) -> UIView {
        return view
    }
    
    func prepareDestinationView(_ userInfo: [String: AnyObject]?, isPresenting: Bool) {
        
        if isPresenting {
            view.layoutIfNeeded()
        }
    }
}

Presenting controller code

extension ChatMessageViewController: View2ViewTransitionPresenting {
    
    func initialFrame(_ userInfo: [String: AnyObject]?, isPresenting: Bool) -> CGRect {
        // test data
        return CGRect(x: 0, y: 100, width: 100, height: 100)
    }
    
    func initialView(_ userInfo: [String: AnyObject]?, isPresenting: Bool) -> UIView {
        return view
    }
    
    func prepareInitialView(_ userInfo: [String : AnyObject]?, isPresenting: Bool) {
        view.layoutIfNeeded()
    }
    
}

Hi,

I was wondering if there is a way to use view2viewtransition between 2 objective c views? Basically I want to use this library 2 show transition effect between 2 xib using objective c code. Hope I ma being clear on my question.

Thanks
