OVERVIEW - I am making a flashcard app. I have gotten to the point where the user can swipe left and right through an array of images. The images are split into 11 different groups and all of the groups add up to one final array which the user can swipe through(code below).
import UIKit
class SecondViewController: UIViewController , UIGestureRecognizerDelegate {
@IBAction func home(_ sender: Any) {
performSegue(withIdentifier: "home", sender: self)
}
@IBOutlet weak var imgPhoto: UIImageView!
struct List {
let words: [String]
var active: Bool
}
let list1 = List(words:["lake", "lamb", "lamp", "lark", "leaf", "leash", "left", "leg", "lime", "lion", "lips", "list", "lock", "log", "look", "love", "lunch"], active: true)
let list2 = List(words: ["ladder", "ladybug", "laughing", "lawnmower", "lemon", "leopard", "leprechaun", "letters", "licking", "lifesaver", "lifting", "lightbulb", "lightning", "listen", "llama"], active: true)
let list3 = List(words: ["alligator", "balance", "ballerina", "balloon", "bowling", "cello", "colors", "curlyhair", "dollar", "dolphin", "elephant", "eyelashes", "gasoline", "goalie", "hula", "jellyfish", "olive", "pillow", "pilot", "polarbear", "rollerskate", "ruler", "silly", "telephone", "television", "tulip", "umbrella", "valentine", "violin", "xylophone", "yellow"], active: true)
let list4 = List(words: ["apple", "ball", "bell", "bubble", "castle", "fall", "fishbowl", "girl", "owl", "pail", "peel", "pool", "smile", "whale", "wheel"], active: true)
let list5 = List(words: ["planet", "plank", "plant", "plate", "play", "plum", "plumber", "plus"], active: true)
let list6 = List(words: ["black", "blanket", "blender", "blocks", "blond", "blood", "blow", "blue"], active: true)
let list7 = List(words: ["flag", "flipflop", "float", "floor", "flower", "fluffy", "flute", "fly"], active: true)
let list8 = List(words: ["glacier", "glad", "glasses", "glide", "glitter", "globe", "glove", "glue"], active: true)
let list9 = List(words: ["clam", "clamp", "clap", "claw", "clean", "climb", "clip", "cloud"], active: true)
let list10 = List(words:["sled", "sleep", "sleeves", "slice", "slide", "slime", "slip", "slow"], active: true)
let list11 = List(words: ["belt", "cold", "dolphin", "elf", "golf", "melt", "milk", "shelf"], active: true)
var imageIndex: Int = 0
var imageList: [String] {
let wordLists = [list1, list2, list3, list4, list5, list6, list7, list8, list9, list10, list11]
let active = wordLists.reduce([]) { (result:[String], list:List) in
if list.active {
return result + list.words
} else {
return result
}
}
return active
}
override func viewDidLoad() {
super.viewDidLoad()
imgPhoto.image = UIImage(named: imageList[imageIndex])
// Do any additional setup after loading the view.
imgPhoto.isUserInteractionEnabled = true
let leftSwipe = UISwipeGestureRecognizer(target: self, action: #selector(Swiped(gesture:)))
leftSwipe.cancelsTouchesInView = false
let rightSwipe = UISwipeGestureRecognizer(target: self, action: #selector(Swiped(gesture:)))
rightSwipe.cancelsTouchesInView = false
leftSwipe.direction = .left
rightSwipe.direction = .right
view.addGestureRecognizer(leftSwipe)
view.addGestureRecognizer(rightSwipe)
}
func Swiped(gesture: UIGestureRecognizer) {
if let swipeGesture = gesture as? UISwipeGestureRecognizer {
switch swipeGesture.direction {
case UISwipeGestureRecognizerDirection.right :
print("User swiped right")
// decrease index first
imageIndex -= 1
// check if index is in range
if imageIndex < 0 {
imageIndex = imageList.count - 1
}
imgPhoto.image = UIImage(named: imageList[imageIndex])
case UISwipeGestureRecognizerDirection.left:
print("User swiped Left")
// increase index first
imageIndex += 1
// check if index is in range
if imageIndex > imageList.count - 1 {
imageIndex = 0
}
imgPhoto.image = UIImage(named: imageList[imageIndex])
default:
break //stops the code/codes nothing.
}
}
}
}
NOW - I am working on a settings page(image below). There is 1 switch for each of the 11 lists of words in the code above. The top most switch would control list1, the second switch would control list2 etc...
THE PROBLEM - is that I want to add functionality to each switch. When a switch is in the off position, the group of images it is associated with should not be included in the final array and will not be displayed when the user is swiping through the flashcards. The code for my settings page thus far is below. I have tried experimenting with different bits of code such as connecting the switch to the ViewController and adding an Override func but I am not sure where to go at this point.
import UIKit
protocol WordSelectionDelegate: class {
func wordSelected(newWord: Word)
}
class MasterViewController: UITableViewController {
var words = [Word]()
weak var delegate: WordSelectionDelegate?
override func prepare(for segue: UIStoryboardSegue, sender: SecondViewController) {
if let vc = segue.destination as? MasterViewController {
vc.wordLists = wordLists
}
}
@IBAction func switchAction(_ sender: UISwitch) {
wordList[sender.tag].active = rollIntoLoanSwitch.isOn
}
override func viewDidLoad() {
super.viewDidLoad()
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
self.words.append(Word(name: "initial /l/ 1 syllable", description: "lake lamb lamp lark leaf leash left leg lime lion lips list lock log look love lunch"))
self.words.append(Word(name: "initial /l/ multisyllabic", description: ""))
self.words.append(Word(name: "intersyllabic /l/", description: ""))
self.words.append(Word(name: "final /l/", description: ""))
self.words.append(Word(name: "initial /pl/", description: ""))
self.words.append(Word(name: "initial /bl/", description: ""))
self.words.append(Word(name: "initial /fl/", description: ""))
self.words.append(Word(name: "initial /gl/", description: ""))
self.words.append(Word(name: "initial /kl/", description: ""))
self.words.append(Word(name: "initial /sl/", description: ""))
self.words.append(Word(name: "final /l/ clusters", description: ""))
}

}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return self.words.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
// Configure the cell...
let word = self.words[indexPath.row]
cell.textLabel?.text = word.name
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt
indexPath: IndexPath) {
let selectedMonster = self.words[indexPath.row]
self.delegate?.wordSelected(newWord: selectedMonster)
if let Detail = self.delegate as? Detail {
splitViewController?.showDetailViewController(Detail, sender: nil)
}
}

Any thoughts on how to go about solving this problem would be greatly appreciated . Thank you
