WDFlashCard

WDFlashCard is a simple lightweight component for displaying flashcards inside iOS apps. Just add front and back view, set flashcard animation type and duration.

Installation:

Manual:

Just download source code and include WDFlashCard/WDFlashCard/WDFlashCardView.swift in your project.

CocoaPods:

target '<TargetName>' do
    use_frameworks!
    pod 'WDFlashCard'
end

Usage

Add UIView to storyboard or Xib file and set WDFlashCard as its class. Also, add two views inside this WDFlashCard view to use them as a back and front view for flash card view. Then set WDFlashCardDelegate (using interface builder or in code) and implement its metods: flipBackView to set back view and flipFrontView to set front view.

class ViewController: UIViewController, WDFlashCardDelegate {
    
    @IBOutlet weak var backView: UIView!
    @IBOutlet weak var frontView: UIView!
    @IBOutlet weak var flashCard: WDFlashCard!
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        flashCard.duration = 2.0
        flashCard.flipAnimation = .flipFromLeft
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    
    //MARK: WDFlashCardDelegate methods
    
    func flipBackView(forFlashCard flashCardView: WDFlashCard) -> UIView {
        return backView
    }
    
    func flipFrontView(forFlashCard flashCardView: WDFlashCard) -> UIView {
        return frontView
    }
}

If you want to disable tap to flip option, you can set flashCard.disableTouchToFlipFesture to true (By default, it is set to true).

flashCard.disableTouchToFlipFesture = true

In that case, you are still able to flip this view. All you need to do is to call flip() method from wherever you need:

flashCard.flip()

For better understanding look at the source code example.
