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
