I have a table view in my restaurant app I’m making. I’m struggling with a problem.I have more restaurants in my app, and I want for every restaurant to display different food, but when I’m selecting any restaurant, I have the same data every where.
I’ll show my code for the first Table View.
This is where I’m declaring the variables (a struct) which I’m using
struct Category {
let title: String
let photoKeyHome: String
}
var datas: [Category] = []
var filteredData: [Category]!
override func viewDidLoad() {
super.viewDidLoad()
filteredData = datas
}
This is where I’m retrieving data from my Firestore (I’m using Firestore and firebase storage).
func getDatabaseRecords() {
let db = Firestore.firestore()
// Empty the array
filteredData = []
db.collection("HomeTableViewRestuarants").getDocuments { (snapshot, error) in
if let error = error {
print(error)
return
} else {
for document in snapshot!.documents {
let data = document.data()
let newEntry = Category(
title: data["title"] as! String,
photoKeyHome: data["photoKeyHome"] as! String
)
self.filteredData
.append(newEntry)
}
}
DispatchQueue.main.async {
self.datas = self.filteredData
self.homeTableView.reloadData()
}
}
}
This is my table view and how I’m moving to the second table view where I have the food.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = homeTableView.dequeueReusableCell(withIdentifier: "homeTableViewCell", for: indexPath) as! homeTableViewCell
let restaurant = filteredData[indexPath.row]
let storageRef = Storage.storage().reference()
let photoRef = storageRef.child(restaurant.photoKeyHome)
cell.myLabel.text = restaurant.title
cell.myImage.sd_setImage(with: photoRef)
cell.myView.layer.cornerRadius = cell.myView.frame.height / 5
cell.myImage.layer.cornerRadius = cell.myImage.frame.height / 5
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
homeTableView.deselectRow(at: indexPath, animated: true)
let vc = RestaurantViewController()
navigationController?.pushViewController(vc, animated: true)
}
This is how im retrieving data from my second table view (RestaurantViewController)
func getDatabaseRecords() {
let db = Firestore.firestore()
// Empty the array
food = []
db.collection("RestaurantViewController").getDocuments { (snapshot, error) in
if let error = error {
print(error)
return
} else {
for document in snapshot!.documents {
let data = document.data()
let newEntry = Food(photoKeyRestaurant: data["photoKeyRestaurant"] as! String, foodName: data["foodName"] as! String, foodDescription: data["foodDescription"] as! String
)
print("document is \(document)")
self.food.append(newEntry)
}
}
DispatchQueue.main.async {
// self.datas = self.filteredData
self.tableView.reloadData()
}
}
}
This is my struct:
struct Food {
var photoKeyRestaurant: String
var foodName: String
var foodDescription: String
}
var food: [Food] = []
And this is my table view for the restaurant view controller
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return food.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "FoodTableViewCell", for: indexPath) as! FoodTableViewCell
let mancare = food[indexPath.row]
let storageRef = Storage.storage().reference()
let photoRef = storageRef.child(mancare.photoKeyRestaurant)
cell.foodImage.sd_setImage(with: photoRef)
cell.descriptionLabel.text = mancare.foodDescription
cell.foodNameLabel.text = mancare.foodName
return cell
}
For each restaurant, how can I have different food ?
