How to hide collection view when table view is searching? - ios

Question

I have collection view inside of my first table view cell. Search bar at the top of the table view (out of table view). Collection views showing as table view cell items count at viewDidLoad(). E.g. If table view cell items count 4 so collection view items count as same 4.
class MainViewController: UIViewController, UITableViewDataSource, UITableViewDelegate,
UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
#IBOutlet weak var searchBar: UISearchBar!
#IBOutlet weak var mainTableView: UITableView!
var imageNames = [ImageNames]()
var priceFood: [Double]!
var searchFoods = [String]()
var filtered = [String]()
var searching = false
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
self.tabBarController?.tabBar.isHidden = false
}
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.navigationBar.isHidden = true
let foodCell = Food(name: ["Hamburger big mac",
"Patates",
"Whopper",
"Steakhouse"], price: [15.0, 20.0, 25.0, 30.0])
searchBar.delegate = self
searchFoods = foodCell.name
priceFood = foodCell.price
imageNames = [
ImageNames(name: "images"),
ImageNames(name: "unnamed"),
ImageNames(name: "unnamed")
// ImageNames(name: "images"),
// ImageNames(name: "images")
]
}
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if searching {
return filtered.count
} else {
return searchFoods.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "MainFoodTableViewCell", for: indexPath) as! MainFoodTableViewCell
// cell.mainFoodCollectionView.delegate = self
// cell.mainFoodCollectionView.dataSource = self
// cell.mainFoodCollectionView.reloadData()
cell.mainFoodCollectionView.tag = indexPath.row
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "CellForFood", for: indexPath) as! MainFoodTitleTableViewCell
if searching {
cell.titleLabel?.text = filtered[indexPath.row]
cell.priceLabel?.text = priceFood[indexPath.row].description
} else {
cell.titleLabel?.text = searchFoods[indexPath.row]
cell.priceLabel?.text = priceFood[indexPath.row].description
}
return cell
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return indexPath.section == 0 ? 130 : 65
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return indexPath.section == 0 ? 100 : 65
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return imageNames.count
}
func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
let width = UIScreen.main.bounds.width
return CGSize(width: width, height: 130)
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "MainFoodCollectionViewCell", for: indexPath) as! MainFoodCollectionViewCell
let img = imageNames[indexPath.row]
cell.mainFoodImage.image = UIImage(named: img.name)
return cell
}
}
extension MainViewController : UISearchBarDelegate {
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
self.searchBar.showsCancelButton = true
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searching = false
searchBar.showsCancelButton = false
searchBar.text = ""
searchBar.resignFirstResponder()
mainTableView.reloadData()
}
I think I did not make sense with this function
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
filtered = searchText.isEmpty ? searchFoods : filtered.filter { (item: String) -> Bool in
return item.range(of: searchText, options: .caseInsensitive, range: nil, locale: nil) != nil
}
// filtered = self.searchFoods.filter ({$0.prefix(searchText.count) == searchText})
searching = true
mainTableView.reloadData()
}
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "MainFoodTableViewCell", for: indexPath) as! MainFoodTableViewCell
cell.mainFoodCollectionView.tag = indexPath.row
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "CellForFood", for: indexPath) as! MainFoodTitleTableViewCell
if searching {
cell.titleLabel?.text = filtered[indexPath.row]
cell.priceLabel?.text = priceFood[indexPath.row].description
} else {
cell.titleLabel?.text = searchFoods[indexPath.row]
cell.priceLabel?.text = priceFood[indexPath.row].description
}
return cell
}
}
