A custom modal transition that presents a controller with an expanding effect while sliding out the presenter remnants.
Simply copy the Xpandr/DAExpandAnimation.swift
file into your project.
Try the example project!
Have your view controller conform to UIViewControllerTransitioningDelegate. Optionally set the collapsedViewFrame
, the expandedViewFrame
and the animationDuration
.
private let animationController = DAExpandAnimation()
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let toViewController = segue.destinationViewController
if let selectedCell = sender as? UITableViewCell {
toViewController.transitioningDelegate = self
toViewController.modalPresentationStyle = .Custom
toViewController.view.backgroundColor = selectedCell.backgroundColor
animationController.collapsedViewFrame = {
return selectedCell.frame
}
animationController.animationDuration = Constants.SomeAnimationDuration
if let indexPath = tableView.indexPathForCell(selectedCell) {
tableView.deselectRowAtIndexPath(indexPath, animated: false)
}
}
}
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return animationController
}
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return animationController
}
Adopting DAExpandAnimationFromViewAnimationsAdapter
provides the following optional delegate methods for tailoring the presenter's UX.
// Does the animation require sliding the presenting view apart? Defaults to true.
var shouldSlideApart: Bool { get }
// Tweaks in the presenting view controller.
func animationsBeganInView(view: UIView, presenting isPresentation: Bool)
func animationsEnded(presenting isPresentation: Bool)
Adopting DAExpandAnimationToViewAnimationsAdapter
provides the following optional delegate methods for tailoring the presentation of a new view controller.
// Additional setup before the animations.
func prepareExpandingView(view: UIView)
func prepareCollapsingView(view: UIView)
// Custom changes to animate.
func animationsForExpandingView(view: UIView)
func animationsForCollapsingView(view: UIView)
// Cleanup after the animations are performed.
func completionForExpandingView(view: UIView)
func completionForCollapsingView(view: UIView)
