VerticalCardSwiper
2.3.1
Tujuan dari proyek ini adalah untuk menciptakan kembali Discover UI di Shazam (yang saya pikir adalah cara yang bagus dan menyenangkan untuk menampilkan konten) dalam kombinasi dengan gaya Tinder kartu menggesek ke kiri/kanan. Gagasan di balik ini adalah bahwa dalam beberapa kasus, Anda tidak ingin menggesek kartu, tetapi tetap tersedia untuk nanti. Implementasi ini memungkinkan untuk itu. Dan ini cara yang menyenangkan untuk berinteraksi dengan konten.
Ini dibangun dengan UICollectionView dan flowlayout khusus.
Untuk menginstal dengan cocoapods, cukup tambahkan baris berikut ke podfile Anda:
pod 'VerticalCardSwiper'Untuk menginstal dengan Carthage, cukup tambahkan baris berikut ke podfile Anda:
github "JoniVR/VerticalCardSwiper" Untuk mencoba VerticalCardSwiper
pod try VerticalCardSwiperatau buka proyek dan jalankan contohnya.
VerticalCardSwiper berperilaku sangat mirip dengan UICollectionView standar. Untuk menggunakannya di dalam UIViewController Anda:
import VerticalCardSwiper
class ExampleViewController : UIViewController , VerticalCardSwiperDatasource {
private var cardSwiper : VerticalCardSwiper !
override func viewDidLoad ( ) {
super . viewDidLoad ( )
cardSwiper = VerticalCardSwiper ( frame : self . view . bounds )
view . addSubview ( cardSwiper )
cardSwiper . datasource = self
// register cardcell for storyboard use
cardSwiper . register ( nib : UINib ( nibName : " ExampleCell " , bundle : nil ) , forCellWithReuseIdentifier : " ExampleCell " )
}
func cardForItemAt ( verticalCardSwiperView : VerticalCardSwiperView , cardForItemAt index : Int ) -> CardCell {
if let cardCell = verticalCardSwiperView . dequeueReusableCell ( withReuseIdentifier : " ExampleCell " , for : index ) as? ExampleCardCell {
return cardCell
}
return CardCell ( )
}
func numberOfCards ( verticalCardSwiperView : VerticalCardSwiperView ) -> Int {
return 100
}
} /// Indicates if side swiping on cards is enabled. Set to false if you don't want side swiping. Default is `true`.
@ IBInspectable public var isSideSwipingEnabled : Bool = true
/// Allows you to enable/disable the stacking effect. Default is `true` (enabled).
@ IBInspectable public var isStackingEnabled : Bool = true
/// The transform animation that is shown on the top card when scrolling through the cards. Default is 0.05.
@ IBInspectable public var firstItemTransform : CGFloat = 0.05
/// The inset (spacing) at the top for the cards. Default is 40.
@ IBInspectable public var topInset : CGFloat = 40
/// The inset (spacing) at each side of the cards. Default is 20.
@ IBInspectable public var sideInset : CGFloat = 20
/// Sets how much of the next card should be visible. Default is 50.
@ IBInspectable public var visibleNextCardHeight : CGFloat = 50
/// Vertical spacing between the focussed card and the bottom (next) card. Default is 40.
@ IBInspectable public var cardSpacing : CGFloat = 40
/// Allows you to set the view to Stack at the Top or at the Bottom. Default is true.
@ IBInspectable public var isStackOnBottom : Bool = true
/// Sets how many cards of the stack are visible in the background
@ IBInspectable public var stackedCardsCount : Int = 1
/**
Returns an array of indexes (as Int) that are currently visible in the `VerticalCardSwiperView`.
This includes cards that are stacked (behind the focussed card).

cardSwiper . moveCard ( at : Int , to : Int )
cardSwiper . deleteCards ( at : [ Int ] )
cardSwiper . insertCards ( at : [ Int ] ) Untuk menangani gerakan gesek, terapkan VerticalCardSwiperDelegate .
class ViewController : UIViewController , VerticalCardSwiperDelegate {
override func viewDidLoad ( ) {
super . viewDidLoad ( )
cardSwiper . delegate = self
}
func willSwipeCardAway ( card : CardCell , index : Int , swipeDirection : SwipeDirection ) {
// called right before the card animates off the screen (optional).
}
func didSwipeCardAway ( card : CardCell , index : Int , swipeDirection : SwipeDirection ) {
// handle swipe gestures (optional).
}
func didCancelSwipe ( card : CardCell , index : Int ) {
// Called when a card swipe is cancelled (when the threshold wasn't reached)
}
func sizeForItem ( verticalCardSwiperView : VerticalCardSwiperView , index : Int ) -> CGSize {
// Allows you to return custom card sizes (optional).
return CGSize ( width : verticalCardSwiperView . frame . width * 0.75 , height : verticalCardSwiperView . frame . height * 0.75 )
}
func didScroll ( verticalCardSwiperView : VerticalCardSwiperView ) {
// Tells the delegate when the user scrolls through the cards (optional).
}
func didEndScroll ( verticalCardSwiperView : VerticalCardSwiperView ) {
// Tells the delegate when scrolling through the cards came to an end (optional).
}
func didDragCard ( card : CardCell , index : Int , swipeDirection : SwipeDirection ) {
// Called when the user starts dragging a card to the side (optional).
}
func didTapCard ( verticalCardSwiperView : VerticalCardSwiperView , index : Int ) {
// Tells the delegate when the user taps a card (optional).
}
func didHoldCard ( verticalCardSwiperView : VerticalCardSwiperView , index : Int , state : UIGestureRecognizer . State ) {
// Tells the delegate when the user holds a card (optional).
}
} Subkelas CardCell untuk menyesuaikan kartu.
class ExampleCardCell : CardCell {
