Setting a delegate to an outlet in a class without an initialiser - ios

Question

I am trying to assign a delegate to a pickerView outlet in a class with a UITableViewCell protocol.
My application is rather basic, it has an usual UIViewController class
class ADScreen: UIViewController{
#IBOutlet var tableView: UITableView!
override func viewDidLoad(){
super.viewDidLoad()
self.tableView.dataSource = self
self.tableView.delegate = self
}
}
with an extension
extension ADScreen: UITableViewDelegate, UITableViewDataSource{
(...)
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
switch indexPath.row {
case 0:
let cell = tableView.dequeueReusableCell(withIdentifier: "tag")!
return cell
(...)
}
As you can see, I am populating the table with custom cells.
class TTViewCell: UITableViewCell{
#IBOutlet var pickerView: UIPickerView!
(...)
}
extension TTViewCell: UIPickerViewDelegate, UIPickerViewDataSource{
(...)
}
The problem is that the class of the cell also has a UIPickerView outlet that I would like to populate, but can't because I have no initialiser to put the pickerView.delegate = self line in, and I'm not sure where do I put it in this case. I've tried to create a custom init() function but it got really complicated over time and wouldn't work anyway with my implementation.

Answer 1

Use override method awakeFromNib() to initialize any properties.
class TTViewCell: UITableViewCell{
#IBOutlet var pickerView: UIPickerView!
override func awakeFromNib() {
super.awakeFromNib()
pickerView.delegate = self
}
}
extension TTViewCell: UIPickerViewDelegate, UIPickerViewDataSource{
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 10 // set number of components
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return 5 // set number of rows
}
}
Check this code.
