I just started programming with Swift a few months ago so to help me learn, I'm working on a project similar to Tinder using Koloda View. I'm using Firebase as my backend. The code I have included below works fine with 6 images assets of cards but I'm trying to figure out a way to create a card for each user and use these custom cards as the data source for the KolodaView.
I created a XIB file to use as a template for these cards but I'm not sure how I can get information from each user in my database to display on these cards. Also, how do I instantiate multiple copies of the XIB file to use for each user?
Sorry for the confusing wording of the question since I am just a beginner I'm having trouble trying to articulate my problem. Please ask me if you need any clarification on what I'm trying to say.
private var numberOfCards: UInt = 5
class ViewController: UIViewController, KolodaViewDataSource, KolodaViewDelegate {
var ids : [String] = []
@IBOutlet weak var kolodaView: KolodaView!
@IBAction func undo(sender: AnyObject) {
kolodaView?.revertAction()
}
@IBAction func left(sender: AnyObject) {
kolodaView?.swipe(SwipeResultDirection.Left)
}
@IBAction func right(sender: AnyObject) {
kolodaView?.swipe(SwipeResultDirection.Right)
}
override func viewDidLoad() {
super.viewDidLoad()
kolodaView.dataSource = self
kolodaView.delegate = self
self.modalTransitionStyle = UIModalTransitionStyle.FlipHorizontal
// Do any additional setup after loading the view, typically from a nib.
}
//MARK: KolodaViewDataSource
func kolodaNumberOfCards(koloda: KolodaView) -> UInt {
return numberOfCards
}
func kolodaViewForCardAtIndex(koloda: KolodaView, index: UInt) -> UIView {
return UIImageView(image: UIImage(named: "Card_like_\(index + 1)"))
}
func kolodaViewForCardOverlayAtIndex(koloda: KolodaView, index: UInt) -> OverlayView? {
return NSBundle.mainBundle().loadNibNamed("OverlayView",
owner: self, options: nil)[0] as? OverlayView
}
//MARK: KolodaViewDelegate
func kolodaDidSwipedCardAtIndex(koloda: KolodaView, index: UInt, direction: SwipeResultDirection) {
//Example: loading more cards
if index >= 3 {
numberOfCards = 6
kolodaView.reloadData()
}
}
func kolodaDidRunOutOfCards(koloda: KolodaView) {
//Example: reloading
kolodaView.resetCurrentCardNumber()
}
func kolodaDidSelectCardAtIndex(koloda: KolodaView, index: UInt) {
UIApplication.sharedApplication().openURL(NSURL(string: "http://yalantis.com/")!)
}
func kolodaShouldApplyAppearAnimation(koloda: KolodaView) -> Bool {
return true
}
func kolodaShouldMoveBackgroundCard(koloda: KolodaView) -> Bool {
return true
}
func kolodaShouldTransparentizeNextCard(koloda: KolodaView) -> Bool {
return true
}
func kolodaBackgroundCardAnimation(koloda: KolodaView) -> POPPropertyAnimation? {
return nil
}
}
