Usage

Basic usage

import UIKit
import JTMaterialTransition

class ViewController: UIViewController {

    weak var presentControllerButton: UIButton?
    var transition: JTMaterialTransition?

    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.transition = JTMaterialTransition(animatedView: self.presentControllerButton)
    }
    
    func didPresentControllerButtonTouch () {
        let controller = SecondViewController()
        
        controller.modalPresentationStyle = .custom
        controller.transitioningDelegate = self.transition
        
        self.present(controller, animated: true, completion: nil)
    }

}

Notes

The animatedView is not directly used, a new view is created based on the frame, backgroundColor properties for the animation. If you don't want to provide a view, you have to set startFrame and startBackgroundColor properties and call init instead of initWithAnimatedView:.

startFrame must be the coordinates relative to the window:

var startFrame = animatedView.superview?.convert(animatedView.frame, to: nil)

Warning

The controller presented must have a backgroundColor else the effect can be a little strange. If you use a UINavigationController or another container don't forget to set the backgroundColor with controllerPresented.view.backgroundColor = UIColor.yourColor.

Requirements

• iOS 8.0 or higher
• Swift 4.2

jtmaterialtransition's Issues

Do we need to use "presentViewController" ?

I am having difficulty using "showViewController"

Does this only work for modal transitions?

JTMaterialTransition.h Needs to import UIKit

Hey! Nice library – just thought I'd point out, modern Xcode projects don't have prefix headers so need to import UIKit to play nicely. Thanks!

can you upgrade this to ios8 style transitions?

would be awesome if i can use this as a navigationController showVIewController transition. Thanks!

Hi！The viewController life cycle abnormality

Hi! @jonathantribouharet

I use the library on my app.

But the viewController not call prefersStatusBarHidden / preferredStatusBarStyle / ViewAppears / ViewDisAppear Methods.

I think the animator don't manage toViewController and formViewController Life Cycle.

But i have no idea due with problem.

Hope you help me.

Transitioning into View

Hello, what would be the best way to transition into the view itself, not just to a color?

Imagine opening the camera view for taking a photo, or a complex view with a lot of controls. Transitioning into a solid color doesn't feel right.

Thank you, if you show me a direction I would like to submit a pull request.

Animation is different if you use a NavigationController

The JTMaterialTransition works perfectly if I use a regular ViewController as the presentedViewController.

If I present a NavigationController or a NavigationController that holds a SWRevealViewController (which is a VC Library that allows you to have drawers), the animation isn't as fluid (it looks worse). Is there any quick workaround to this?
