A custom modal transition that presents and dismiss a controller inside an expanding and shrinking _bubble_.
# Screenshot
# Usage
Install through [CocoaPods](http://cocoapods.org):
```
pod 'BubbleTransition', '~> 3.2.0'
use_frameworks!
```
Install through [Carthage](https://github.com/Carthage/Carthage):
```
github "andreamazz/BubbleTransition"
```
# Setup
Have your view controller conform to `UIViewControllerTransitioningDelegate`. Set the `transitionMode`, the `startingPoint`, the `bubbleColor` and the `duration`.
```swift
let transition = BubbleTransition()
public override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let controller = segue.destination
controller.transitioningDelegate = self
controller.modalPresentationCapturesStatusBarAppearance = true
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](https://gist.github.com/andreamazz/9b0d6c7db065555ec0d7).
# Swipe to dismiss
You can use an interactive gesture to dismiss the presented controller. To enable this gesture, prepare the interactive transition:
```swift
let interactiveTransition = BubbleInteractiveTransition()
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let controller = segue.destination as? ModalViewController {
controller.transitioningDelegate = self
controller.modalPresentationStyle = .custom
controller.modalPresentationCapturesStatusBarAppearance = true
controller.interactiveTransition = interactiveTransition
interactiveTransition.attach(to: controller)
}
}
```
and implement `interactionControllerForDismissal` in your presenting controller:
```swift
func interactionControllerForDismissal(using animator: UIViewControllerAnimatedTransitioning) -> UIViewControllerInteractiveTransitioning? {
return interactiveTransition
}
```
In the presented controller make sure to call `finish()` on the interactive gesture if you need to quickly dismiss from a button press instead. Check the sample code for more info.
You can decide the gesture threshold and the swipe direction:
```swift
interactiveTransition.interactionThreshold = 0.5
interactionThreshold.swipeDirection = .up
```
# Properties
```swift
var startingPoint = CGPointZero
```
The point that originates the bubble.
```swift
var duration = 0.5
```
The transition duration.
```swift
var transitionMode: BubbleTranisionMode = .present
```
The transition direction. Either `.present`, `.dismiss` or `.pop`.
```swift
var bubbleColor: UIColor = .white
```
The color of the bubble. Make sure that it matches the destination controller's background color.
