Best way of working with ListView - ios

Question

Hey guys I´m in the process of learning swift right now and I try to program a Game. I want to show a list with items and different attributes to these Items.
So first I have User choice of where they can select either Food or Toys or other stuff coming in the future. Here I tried to only do one ViewController and change the stuff inside depending on the choice. Right now I have these Items in an Array from a Class.
They look like this:
class FoodData {
var name: String
var description = "Basic Food"
var owned = 0
var taste = 0
var price = 0
var water = 0
var image = "default.png"
init(name: String){
self.name=name
}
}
class ToyData {
var name: String
var description = "Basic Item"
var owned = 0
var price = 0
var joy = 0
var image = "default.png"
init(name: String){
self.name=name
}
}
I initialise these with:
var foodLoad=[FoodData]()
func loadFoodData(){
foodLoad.append(FoodData(name: "IceCream"))
foodLoad[0].description="Very Cold"
foodLoad[0].owned=10
}
Same style for the Toys. Now I have these two Classes in two Arrays called foodLoad[i] and toyLoad[I]
For the Table View I fill it with the protocols
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let shopCell = tableView.dequeueReusableCell(withIdentifier: shopCellIdentifier, for: indexPath) as! ShopCellStyle
shopCell.shopNameLabel?.text = shopData[indexPath.row].name
shopCell.shopImageView?.image = UIImage(named: shopData[indexPath.row].image)
shopCell.shopPriceLabel?.text = String(shopData[indexPath.row].price) + currency
return shopCell
So my Idea was to assign shopData with the User choice.
But if I assign shopData = foodLoad, I can't change that to toyLoad anymore. So maybe you can give me a hint of how to solve this the best way.

Answer 1

for your cellForRowAt indexPath:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let shopCell = tableView.dequeueReusableCell(withIdentifier: "shopCellIdentifier", for: indexPath) as! ItemCell
if selection == "food" {
shopCell.shopNameLabel?.text = foodLoad[indexPath.row].name
shopCell.shopImageView?.image = UIImage(named:
foodLoad[indexPath.row].image)
shopCell.shopPriceLabel?.text = String(foodLoad[indexPath.row].price) + currency
}
else if selection == "toys" {
shopCell.shopNameLabel?.text = toyLoad[indexPath.row].name
shopCell.shopImageView?.image = UIImage(named:
toyLoad[indexPath.row].image)
shopCell.shopPriceLabel?.text = String(toyLoad[indexPath.row].price) + currency
}
return shopCell
}
You'd also want the numberOfRowsInSection UITableView function. Call tableview.reloadData() when the user changes the type selection.
