我使用Core Date保存姓名和电话号码我想通过触摸单元拨打电话这里是我的代码：import UIKit import CoreData
class ViewController：UIViewController {
@IBOutlet weak var tableView: UITableView!
var people = [Person]()
override func viewDidLoad() {
super.viewDidLoad()
let fetchRequest: NSFetchRequest<Person> = Person.fetchRequest()
do {
let people = try PersistenceService.context.fetch(fetchRequest)
self.people = people
self.tableView.reloadData()
} catch {}
}
@IBAction func onPlusTapped() {
let alert = UIAlertController(title: "Add Person", message: nil, preferredStyle: .alert)
alert.addTextField { (textField) in
textField.placeholder = "Name"
}
alert.addTextField { (textField) in
textField.placeholder = "Phone number"
textField.keyboardType = .numberPad
}
let action = UIAlertAction(title: "Post", style: .default) { (_) in
let name = alert.textFields!.first!.text!
let phoneNumber = alert.textFields!.last!.text!
let person = Person(context: PersistenceService.context)
person.name = name
person.phoneNumber = phoneNumber
PersistenceService.saveContext()
self.people.append(person)
self.tableView.reloadData()
}
alert.addAction(action)
present(alert, animated: true, completion: nil)
}
override var prefersStatusBarHidden：Bool }
扩展ViewController：UITableViewDataSource {func numberOfSections（在tableView：UITableView中） - > Int {return 1}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return people.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: .subtitle, reuseIdentifier: nil)
cell.textLabel?.text = people[indexPath.row].name
cell.detailTextLabel?.text = people[indexPath.row].phoneNumber
return cell
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == .delete) {
people.remove(at: indexPath.item)
tableView.deleteRows(at: [indexPath], with: .automatic)
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
UIApplication.shared.openURL(NSURL(string: "tel://" + (people[indexPath.row].phoneNumber?.description)!)! as URL)
print(people[indexPath.row].phoneNumber?.description)
}
}

无需添加@IBAction，您可以使用UITableViewDelegate中的didSelectRow
如果你在
UITableViewCell内有一个UIButton，你已经在UITableView内实现了didSelectRowAt使用IBActions
