Installation

  • Add the following to your
    Podfile
    and run
    pod install
    ruby
    pod 'AZTransitions'
    
  • or add the following to your
    Cartfile
    and run
    carthage update
    github "azimin/AZTransitions"
    
  • or clone as a git submodule,

  • or just copy

    AZTransitions/Source/CustomModalTransition.swift
    into your project.

Code Example

To create any custom transition just subclass

CustomModalTransition
:
class FashionTransition: CustomModalTransition { 
  override init() {
    super.init(duration: 0.5)
  }
}

--

Then set as

az_modalTransition
to nessesary view just before presenting it
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
  segue.destination.customModalTransition = FashionTransition()
}

or

func show() {
  let viewController = UIViewController()
  viewController.customModalTransition = FashionTransition()
  self.present(viewController, animated: true, completion: nil)
}

--

To have custom present animation, just implement

performTransition(interactive: Bool)
inside your
FashionTransition
class:
func performTransition(interactive: Bool) {
  self.presentedViewController.view.alpha = 0.0

UIView.animate(withDuration: duration, animations: { self.presentedViewController.view.alpha = 1.0 self.presentingViewController.view.alpha = 0.0 }, completion: { (completed) in self.presentingViewController.view.alpha = 1.0 self.finishAnimation(completion: nil) }) }

As you may have guessed, you have different properties. The main ones:

  • duration
    — transition duration
  • presentingViewController
    — the presenting view controller (bottom one)
  • presentedViewController
    — view controller that is going to be presented (top one)

You can animate them as you want.

🔥IMPORTANT🔥 don't forget to call

finishAnimation(completion: nil)
in the end.

In this case animation will be:

Animation code example

UIModalPresentationStyle

Of course sometimes you want to use diffenret modal presentation styles (for example

overCurrentContext
), in this case you can call
setCustomModalTransition(customModalTransition: CustomModalTransition, inPresentationStyle: UIModalPresentationStyle)
of UIViewController instead of setting
customModalTransition
directly.

More

You have different properties and methods to help you:

  • performDismissingTransition(interactive: Bool)
    to implement custom transition animation when dismissing
  • fromViewController
    /
    toViewController
    in term of Apple transition. They are reversed in presenting and dismissing transitions.
  • transitionContainerView
    view where the transition takes place (
    resentingViewController.view
    and
    presentedViewController.view
    located on inside
    transitionContainerView
    ), so you can add your custom views here to make animation more interesting (see
    iOS Example
    )
  • Some methods for interactive animations (example will be added be soon)
  • Some method to work with orientation changing things (example will be added be soon)
