What is this?

This pod allows you create a custom transition between:

  • a cell (UITableViewCell or UICollectionViewCell) and a details UIViewController
  • two UIViewController

Using both a modal present(UIViewController, animated: Bool, completion: nil) or a UINavigationController push.

Example Project

The project contains an example of each type of transition. To run the example project, clone the repo, and run pod install from the Example directory.

Usage

Create a transition manager in the viewController where you want the transition to start.

let manager = MatchTransitionManager()

Once you want to push or present a new UIViewController, instantiate it:

let storyboard = UIStoryboard(name: "StoryboardName", bundle: nil)
let detailsViewController = storyboard.instantiateViewController(withIdentifier: "DetailsControllerIdentifier") as! DetailsControllerClass
  • Setup from Cell to details UIViewController

When you want the animation to start from a cell, get the selectedCell:

let selectedCell = collectionView.cellForItem(at: indexPath) as! YourCellClass

setup your [Match]:

let matches: [Match] = [
  Match(tag: "SomeUniqueName", from: selectedCell.someView, to: detailsViewController.someView),
  Match(tag: "OtherName", from: selectedCell.otherView, to: detailsViewController.otherView),
]

setup your MatchTransition:

manager.setupTransition(from: selectedCell,
                        inside: self,
                        to: detailsViewController,
                        with: matches,
                        transitionType: TransitionType)
  • Setup from UIViewController to UIViewController

Create your [Match] between views of your current UIViewController(self) and the details UIViewController:

let matches: [Match] = [
  Match(tag: "SomeUniqueName", from: self.someView, to: detailsViewController.someView),
  Match(tag: "OtherName", from: self.otherView, to: detailsViewController.otherView),
]

setup your MatchTransition:

manager.setupTransition(from: self,
                        to: destinationVC,
                        with: matches,
                        transitionType: TransitionType)
  • Choosing TransitionType and starting the transition

When setting up the MatchTransition you have to pass a TransitionType,
which can either be .modal or .push.

  • .modal requires no further setup:

    1. Simply call present(detailsViewController, animated: true) and let MatchTransition do the work!
  • .push requires some more steps for everything to work smoothly:

    1. Both UIViewController involved in the transition must have the same copy of MatchTransitionManager

    2. In the viewDidAppear() of each controller set the navigationController?.delegate = self
    3. Conform to UINavigationControllerDelegate in both controllers,
      depending on which operation you want the transition to happen, return the corresponding transition from the manager.
      Then for all other cases set the delegate to nil and return nil:

      func navigationController(_ navigationController: UINavigationController, animationControllerFor operation: UINavigationController.Operation, from fromVC: UIViewController, to toVC: UIViewController) -> UIViewControllerAnimatedTransitioning? {
        if operation == .push {
            return manager.transition(for: .presenting)
        }
        navigationController.delegate = nil
        return nil
      }
    4. You can now call push(detailsViewController, animated: true) and enjoy the transition!

FAQ

  • What is a Match?
    It’s an object that connects two views, one from the initial ViewController or cell, and the other from the details ViewController.
    To create one simply give it a unique tag, and pass the two views:
Match(tag: "SomeUniqueName", from: selectedCell.someView, to: detailsViewController.someView)

Tips

  • Always add a Match between the cell’s contentView and the detailsViewController view

  • The order of your Match in the array is very important! It determines the order in which the views are displayed in the transition, in front of or behind the others

  • In the case of a transition of type .push, both controllers must have the same instance of the manager

Installation

MatchTransition is available through CocoaPods. To install
it, simply add the following line to your Podfile:
