I have a table view that is subclassed and extended, then being set up in the View controller. The problem that I'm having is the delegate method ViewForHeaderInSection isn't being called, while the normal data source methods are being called.
(this is the TableView setup method, is called in ViewDidLoad. The table view is connected to the View Controller with IBOutlet)
func setup() {
self.dataSource = self as UITableViewDataSource
self.delegate = self
let nib = UINib(nibName: "MyTableViewCell", bundle: nil)
self.register(nib, forCellReuseIdentifier: "MyCell")
}
These are the extensions
extension MyTableView: UITableViewDataSource,UITableViewDelegate {
func numberOfSections(in tableView: UITableView) -> Int {
//print(Genres.total.rawValue)
return Genres.total.rawValue
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if let tableSection = Genres(rawValue: section), let articleData = articleDictionary[tableSection] {
// print(articleData.count)
return articleData.count
}
print(0)
return 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "MyCell") as! MyTableViewCell
if let tableSection = Genres(rawValue: indexPath.section), let article = articleDictionary[tableSection]?[indexPath.row]{
cell.cellTitle.text = article.articleTitle
cell.cellImageView.image = article.articleImage
cell.cellEmojiReaction.text = article.articleEmojis
}
return cell
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.bounds.width, height: 40.0))
view.backgroundColor = .brown
let label = UILabel(frame: CGRect(x: 16, y: 0, width: tableView.bounds.width, height: 40))
label.textColor = .blue
let tableSection = Genres(rawValue: section)
switch tableSection {
case .breakingNews?:
label.text = "Breaking News"
case .scienceAndTech?:
label.text = "Science and Tech"
case .entertainment?:
label.text = "Entertainment"
case .sports?:
label.text = "Sports"
default:
label.text = "Invalid"
}
print("Function Run")
view.addSubview(label)
print(label.text ?? "Nothing Here")
return view
}
}
Here is the View controller Code:
class ViewController: UIViewController {
@IBOutlet weak var myTableView: MyTableView!
override func viewDidLoad() {
super.viewDidLoad()
myTableView.setup()
}
}
Is there any specific reason why the delegate method isn't being called? Thank you in advance for your time.
