Question

我试图根据所点击的单元格来更改按钮及其功能。目前，我有用户可以看到的医院列表。单击的单元格将打开一个包含两个标签，图像和按钮的详细信息。除按钮外，所有内容均按键入方式工作。我希望更改每个单元格以匹配给定医院的电话号码。有什么想法吗？

import UIKit
var hospital = ["Mercy Medical Center"]
var hospitalDesc = ["Roseburg"]
var myIndex = 0

class PhoneBookTableViewController: UITableViewController {

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return hospital.count
    }
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "PBCell", for: indexPath)

        cell.textLabel?.text = hospital[indexPath.row]
        cell.detailTextLabel?.text = hospitalDesc[indexPath.row]

        return cell
    }
    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        myIndex = indexPath.row
        performSegue(withIdentifier: "segue", sender: self)
    }
}


class PhoneBookDetail: UIViewController{

    @IBOutlet weak var titleLabel: UILabel!
    @IBOutlet weak var descLabel: UILabel!
    @IBOutlet weak var myImageView: UIImageView!
    @IBOutlet weak var callHospital: UIButton!

    let phoneVA = "tel://5412175034"

    override func viewDidLoad() {
        super.viewDidLoad()

        titleLabel.text = hospital[myIndex]
        descLabel.text = hospitalDesc[myIndex]
       myImageView.image = UIImage(named: hospital[myIndex] + ".jpg")
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}

声明一个用于管理医院详细信息的结构，并使用方法struct Hospital{ var name = "" var location = "" var contact = "" var image = "" } class PhoneBookTableViewController : UITableViewController{ var hospitals :[Hospital] = [Hospital]() var myIndex = 0 override func viewDidLoad() { super.viewDidLoad() hospitals.append(Hospital(name: "Mercy Medical Center", location: "Roseburg", contact: "tel://5412175034", image: "0.jpg")) } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { return hospitals.count } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "PBCell", for: indexPath) let hospital = hospitals[indexPath.row] cell.textLabel?.text = hospital.name cell.detailTextLabel?.text = hospital.location return cell } override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { myIndex = indexPath.row performSegue(withIdentifier: "Detail", sender: self) } override func prepare(for segue: UIStoryboardSegue, sender: Any?) { if segue.identifier == "Detail" { let destinationVC = segue.destination as! PhoneBookDetail let hospital = hospitals[myIndex] destinationVC.selectedHospital = hospital //OR destinationVC.callHospital.setTitle(hospital.contact, for: UIControl.State.normal) destinationVC.titleLabel.text = hospital.name destinationVC.descLabel.text = hospital.location destinationVC.myImageView.image = UIImage(named: hospital.image) } } } class PhoneBookDetail: UIViewController{ var selectedHospital : Hospital = Hospital() @IBOutlet weak var titleLabel: UILabel! @IBOutlet weak var descLabel: UILabel! @IBOutlet weak var myImageView: UIImageView! @IBOutlet weak var callHospital: UIButton! override func viewDidLoad() { super.viewDidLoad() titleLabel.text = selectedHospital.name descLabel.text = selectedHospital.location myImageView.image = UIImage(named: selectedHospital.image) let phoneVa = selectedHospital.contact print(phoneVa) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() } }通过或直接分配。这是您的代码@Wesley Bryant的修改版本

根据您的要求更改“ segue标识符”

Answer 2

首先，您必须在tableView方法之后在PhoneBookTableViewController中声明prepareSegue方法

 override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "segue" {
//write the name of view controller where you want to show the details
            let destinationVC = segue.destination as! ViewController

//make one global variable in viewController where you want to show the details and set that variable in this prepare method
//here phoneNo is global variable of viewController where you want to show the data

            destinationVC.phoneNo. = phoneVA
            destinationVC.delegate = self
        }
    }
