DMSwipeCards

Features

• Swift 3
• Custom views for the card & overlay
• Generic
• Dynamically add new cards on top or on the bottom
• Lazy view loading

Setup

pod 'DMSwipeCards'

Usage

First import the module:

import DMSwipeCards

Next create an instance of a DMSwipeCardsView:
(Element can be your custom model, or just String)

let swipeView = DMSwipeCardsView<Element>(frame: frame,
                                          viewGenerator: viewGenerator,
                                          overlayGenerator: overlayGenerator)

Views get loaded lazy, so you have to provide DMSwipeCardsView with a ViewGenerator and optionally an OverlayGenerator.

let viewGenerator: (String, CGRect) -> (UIView) = { (element: Element, frame: CGRect) -> (UIView) in
  // return a UIView here
}

let overlayGenerator: (SwipeMode, CGRect) -> (UIView) = { (mode: SwipeMode, frame: CGRect) -> (UIView) in
  // return a UIView here
}

Adding cards

To add new cards, just call the addCards method with an array of the previously defined Element:

swipeView.addCards([Element], onTop: true)

Delegate

DMSwipeCardsView has a delegate property so you can get informed when a card has been swipped. The delegate has to implement following methods:

func swipedLeft(_ object: Any)
func swipedRight(_ object: Any)
func cardTapped(_ object: Any)
func reachedEndOfStack()

The object parameter is guarenteed to have the type Element. Sadly generics don’t work here.

Example

To run the example, first run pod install in the Example directory.
