CardStackController

卡片视图控制器

https://github.com/jobandtalent/CardStackController

iOS custom controller used in the Jobandtalent app to present new view controllers as cards.

This controller behaves very similar to UINavigationController, maintaining a stack of ViewControllers. The presentation of new view controllers is different though. New view controllers are presented as a new “Card” in front of the current context. The next GIFs show the control in action.

Installation

Use Cocoapods to install this custom control in your project.

pod ‘CardStackController’, '~> 0.1.0’

Usage

Use the main and only public class CardStackController to present or stack new view controllers.
After creating and configuring CardStackController, present it modally (it doesn’t need to be animated). Once the controller itself is presented, you can start stacking cards by calling stack(viewController:) method.

Example of usage:

cardStackController.delegate = self
cardStackController.cardScaleFactor = CGFloat(firstSlider.value)
cardStackController.firstCardTopOffset = CGFloat(secondSlider.value)
cardStackController.topOffsetBetweenCards = CGFloat(thirdSlider.value)
cardStackController.verticalTranslation = CGFloat(fourthSlider.value)
cardStackController.automaticallyDismiss = false
present(cardStackController, animated: false, completion: nil)

let root = newController()
root.delegate = self
cardStackController.stack(viewController: root)

This control is highly customisable and contains many features, among the ones we highlight:

• The user can dismiss cards by dragging them down.

• It is possible to tune the damping and frequency values of the presenting animation to achieve all kinds of animation curves.

• It is possible to customise the top distance between cards, the amount each card gets resized, the size of each card…

• There are many convenient methods to unstack cards: unstackAll, unstackUntilRoot, unstackLast, etc.
