for a couple days now I been trying to get this working. I want to show a UICollectionView within a UITableViewController class. I have a searchbar to filter for items, but when I dismiss the searchbar, I want the collectionview to appear. I have included my entire code, maybe someone of you can help me to get this to work .. I tried calling func configureCollectionView at different places, but none of them seem to work. All the Cells I am registering are perfectly working (I know so, because they work in other controllers ..)
Thanks!!
private let reuseIdentifier = "SearchThisCell"
class SearchController: UITableViewController, UISearchBarDelegate, UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout {
var item1 = [Item1]()
var searchbar = UISearchBar()
var filteredItem = [Item1]()
var inSearchMode = false
var collectionView: UICollectionView!
var collectionViewEnabled = true
var item2 = [Item2]()
override func viewDidLoad() {
super.viewDidLoad()
// register cell classes
tableView.register(SearchThisCell.self, forCellReuseIdentifier: reuseIdentifier)
tableView.separatorInset = UIEdgeInsets(top: 0, left: 75, bottom: 0, right: 75)
tableView.separatorStyle = .none
configureSearchBar()
configureCollectionView()
fetchItem1()
fetchItem2()
}

let overviewVC = OverviewController(collectionViewLayout: UICollectionViewFlowLayout())

}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
searchbar.showsCancelButton = true
collectionView.isHidden = false
collectionViewEnabled = true
}
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
let searchText = searchText.lowercased()
if searchText.isEmpty || searchText == " " {
inSearchMode = false
tableView.reloadData()
} else {
inSearchMode = true
filteredItem = item.filter({ (item) in
return item.itemname.contains(searchText)
})
tableView.isHidden = false
tableView.reloadData()
}
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchbar.endEditing(true)
searchbar.showsCancelButton = false
inSearchMode = false
searchbar.text = nil
collectionViewEnabled = true
configureCollectionView()
tableView.isHidden = true
tableView.reloadData()
}
and then come the fetch functions, which are working as they supposed to.
