A custom modal transition that presents and dismiss a controller inside an expanding and shrinking bubble.
Install through CocoaPods:
pod 'BubbleTransition', '~> 3.0.0'
use_frameworks!
Install through Carthage:
github "andreamazz/BubbleTransition"
Have your view controller conform to UIViewControllerTransitioningDelegate
. Set the transitionMode
, the startingPoint
, the bubbleColor
and the duration
.
let transition = BubbleTransition()
public override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let controller = segue.destination
controller.transitioningDelegate = self
controller.modalPresentationStyle = .custom
}
// MARK: UIViewControllerTransitioningDelegate
public func animationController(forPresented presented: UIViewController, presenting: UIViewController, source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
transition.transitionMode = .present
transition.startingPoint = someButton.center
transition.bubbleColor = someButton.backgroundColor!
return transition
}
public func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
transition.transitionMode = .dismiss
transition.startingPoint = someButton.center
transition.bubbleColor = someButton.backgroundColor!
return transition
}
You can find the Objective-C equivalent here.
You can use an interactive gesture to dismiss the presented controller. To enable this gesture, prepare the interactive transition:
let interactiveTransition = BubbleInteractiveTransition()
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let controller = segue.destination
controller.transitioningDelegate = self
controller.modalPresentationStyle = .custom
interactiveTransition.attach(to: controller)
}
and implement interactionControllerForDismissal
in your presenting controller:
func interactionControllerForDismissal(using animator: UIViewControllerAnimatedTransitioning) -> UIViewControllerInteractiveTransitioning? {
return interactiveTransition
}
You can decide the gesture threshold and the swipe direction:
interactiveTransition.interactionThreshold = 0.5
interactionThreshold.swipeDirection = .up
var startingPoint = CGPointZero
The point that originates the bubble.
var duration = 0.5
The transition duration.
var transitionMode: BubbleTranisionMode = .present
The transition direction. Either .present
, .dismiss
or .pop
.
var bubbleColor: UIColor = .white
The color of the bubble. Make sure that it matches the destination controller's background color.
