Usage
Basics
Set modalPresentationCapturesStatusBarAppearance
to true
in your modal view controller, and override the preferredStatusBarStyle
variable to return .lightContent
.
Additionally, the UIScrollView
instances which should be tracked for the swipe-to-dismiss gesture should have their backgroundColor
set to .clear
.
Presentation
The transition can be called from code or using a storyboard.
To use via storyboards, just setup a custom segue (kind
set to custom
), and set the class
to DeckSegue
.
Hereʼs a snippet showing usage via code. Just replace ModalViewController()
with your view controller's class and youʼre good to go.
let modal = ModalViewController()
let transitionDelegate = DeckTransitioningDelegate()
modal.transitioningDelegate = transitionDelegate
modal.modalPresentationStyle = .custom
present(modal, animated: true, completion: nil)
Dismissal
By default, DeckTransition has a swipe-to-dismiss gesture which is automatically enabled when your modalʼs main UIScrollView
is scrolled to the top.
You can opt-out of this behaviour by passing in false
for the isSwipeToDismissEnabled
parameter while initialising your DeckTransitioningDelegate
.
UIScrollView
detection
DeckTransition has an internal heuristic to determine which UIScrollView
should be tracked for the swipe-to-dismiss gesture. In general, this should be sufficient for and cover most use cases.
However there are some edge cases, and should you run into one, these can we worked around by making your modal view controller conform to the DeckTransitionViewControllerProtocol
protocol. More information about this can be found in the documentation page about UIScrollView detection.
Snapshots
For a variety of reasons, and especially because of iOS 11's safe area layout, DeckTransition uses a snapshot of your presenting view controller's view instead of using the view directly. This view is automatically updated whenever the frame is resized.
However, there can be some cases where you might want to update the snapshot view by yourself, and this can be achieved using the following one line snippet:
(presentationController as? DeckSnapshotUpdater)?.requestPresentedViewSnapshotUpdate()
All this does is request the presentation controller to update the snapshot.
You can also choose to update snapshot directly from the presenting view controller, as follows:
(presentedViewController?.presentationController as? DeckSnapshotUpdater)?.requestPresentedViewSnapshotUpdate()
It's worth noting that updating the snapshot is an expensive process and should only be used if necessary, for example if you are updating your entire app's theme.
