如何在viewDidLoad上调用tableView

Question

我是iOS新手，正在尝试从selectedContact输出数据。它适用于addressLabel.text，但我不知道当它是表视图时如何调用它？

class ContactDetailsVC: UITableViewController {
@IBOutlet var contactDetailsTableView: UITableView!

@IBOutlet var addressLabel: UILabel!

let context = (UIApplication.shared.delegate as! AppDelegate).persistentContainer.viewContext

var persons = [Persons]()

var selectedContact: Persons? {
didSet {
getContactDetails()
}
}

override func viewDidLoad() {
super.viewDidLoad()

title = "Contact Details"
navigationController?.navigationBar.prefersLargeTitles = true

contactDetailsTableView = selectedContact?. // <---- this line

addressLabel.text = ("Address (selectedContact?.address ?? "")")            
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {               
return 5               
}

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let cell = tableView.dequeueReusableCell(withIdentifier: "contactDetailsCell", for: indexPath)

cell.textLabel?.text = persons[indexPath.row].firstName! + "n"
+ persons[indexPath.row].lastName! + "n"
+ persons[indexPath.row].company! + "n"
+ persons[indexPath.row].phone! + "n"
+ persons[indexPath.row].email! + "n"

return cell
}
}

Answer 1

您应该使用以下委托方法：

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let selectedPerson = persons[indexPath.row]
// Here you can know what person was selected
}
