デコードされた json データを UICollectionView で使用しようとしています。私が抱えている問題は、セルが空白になっていることです。
print(playing)
またはコンソールを使用してデコードの結果を印刷するとprint(searchs)
、適切なjsonデータが表示されます。問題はvar = nowPlaying = [Results]()
、コンソールに何も出力されない場合[]
です。
使用しようとするvar nowPlaying = [NowPlaying]()
と、エラーが表示Value of type 'FilmsViewController.NowPlaying' has no member title
されlet title = film.title
、コンソールにのみ表示されます[]
私が解決しようとしているのは、UICollectionView 内にデータを表示する方法です。
コード:
import UIKit
import AFNetworking
class FilmsViewController: UIViewController, UICollectionViewDelegate,
UICollectionViewDataSource, UICollectionViewDelegateFlowLayout,
UISearchBarDelegate, UITextFieldDelegate {
var nowPlaying = [Results]()
struct NowPlaying: Codable {
let results: [Results]
}
struct Results: Codable {
let title: String
let poster_path: String?
let id: Int
}
override func viewDidLoad() {
super.viewDidLoad()
self.filmsCollection.dataSource = self
self.filmsCollection.delegate = self
newFilms()
print(nowPlaying)
print(nowPlaying.count)
}
func collectionView(_ _collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if searchBar.text != "" {
return searchTitle.count
} else {
return nowPlaying.count
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = filmsCollection.dequeueReusableCell(withReuseIdentifier: "filmCell", for: indexPath) as! FilmCell
if searchBar.text == "" {
let film = nowPlaying[indexPath.row]
let title = film.title
let poster = film.poster_path
let baseUrl = "http://image.tmdb.org/t/p/w500"
let imageUrl = URL(string: baseUrl + poster!)
cell.titleLabel.text = title
cell.posterImage.setImageWith(imageUrl!)
}
return cell
}
