Alt görünüm ile hızlı çalışmayan delegasyon

Düzenleme: Birisi bunun başka bir sorunun kopyası olduğunu öne sürdü. Ben uygulamadım:
- (NSInteger) tableView: (UITableView *) tableView numberOfRowsInSection: (NSInteger) bölüm // (elbette hızlı olarak).
Bir ViewController'da programlı olarak bir tableView oluşturur ve onu bir alt görünüm olarak eklerim. İki uzantı aracılığıyla UITableViewDelegate ve UITableViewDataSource'u benimseyen DataSource adlı bir sınıfım var.
Burada verilen bir örneği takip ediyorum
Bir hata alıyorum:
ViewController tableView: numberOfRowsInSection:]: 0x7f88cc406ac0 'örneğine gönderilen tanınmayan seçici
0x7f88cc406ac0, içeren ViewController'ın adresidir.
İçeren ViewController'ın bir uzantı aracılığıyla UITableViewDelegate'i benimsemesini sağlasam ve ardından tableView: numberOfRowsInSection'ın DataSource uygulamasını çağırsam bile hala hatayı görüyorum.
Fikirler?
UIKit'i içe aktar
class GenericDataSource: NSObject {
tanımlayıcı = "hücre" olsun
var array: [Herhangi] = ["Köpekler", "Kediler", "Fareler"]
func registerCells (forTableView tableView: UITableView) {
tableView.register (UITableViewCell.self, forCellReuseIdentifier: tanımlayıcı)
// tableView.register (UINib (nibName: "", bundle: nil), forCellReuseIdentifier: tanımlayıcı)
}
func loadCell (atIndexPath indexPath: IndexPath, forTableView tableView: UITableView) -> UITableViewCell {
// let cell = tableView.dequeueReusableCell (withIdentifier: identifier, for: indexPath)
let hücre: UITableViewCell = UITableViewCell (stil: UITableViewCellStyle.subtitle, reuseIdentifier: "hücre")
hücre.textLabel! .text = array [indexPath.row] olarak? Dize
dönüş hücresi
}
}
// UITableViewDataSource
uzantı GenericDataSource: UITableViewDataSource {
func numberOfSections (tableView: UITableView) -> Int {
dönüş 0
}
func tableView (_ tableView: UITableView, numberOfRowsInSection bölüm: Int) -> Int {
return array.count
}
func tableView (_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
self.loadCell döndür (atIndexPath: indexPath, forTableView: tableView)
}
}
// UITableViewDelegate
extension GenericDataSource: UITableViewDelegate {

}
eklenti ViewController: UITableViewDelegate {

}
func tableView (_ tableView: UITableView, numberOfRowsInSection bölüm: Int) -> Int {
return dataSource.tableView (tableView, numberOfRowsInSection: bölüm)
}
func tableView (_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
return dataSource.tableView (tableView, cellForRowAt: indexPath)
}
}
func requestTableView () -> UITableView {
UITableView döndür (çerçeve: UIScreen.main.bounds, stil: UITableViewStyle.plain)
}
class ViewController: UIViewController {
var tableView: UITableView?
var dataSource = GenericDataSource ()
override func viewDidLoad () {
super.viewDidLoad ()
tableView = requestTableView ()
eğer (tableView! = nil) {
self.tableView! .delegate = self
self.tableView! .dataSource = dataSource
self.view.addSubview (self.tableView!)
}
}
}
