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

For a nice working demo sample, please take a look the Example project.
To run the example, first run pod install in the Example directory.
