swift - 将 tableviewcell 连接到多个 View Controller

Question

import Foundation
import UIKit

class ServiceLines: UIViewController{

    @IBOutlet weak var servicesTableView: UITableView!

    var ServiceA: [Service] = []
    var identities = [String]()

    override func viewDidLoad(){
        super.viewDidLoad()

        ServiceA = Services()
        identities = ["Service1","Service2","Service3"]

    }
    func Services() -> [Service]{

        var releaseServices: [Service] = []

        let Service1 = Service(titled: "Test1", description: "Test", image: #imageLiteral(resourceName: "Test"))
        let Service2 = Service(titled: "Test2", description: "Test", image: #imageLiteral(resourceName: "Test"))
        let Service3 = Service(titled: "Test3", description: "Test", image: #imageLiteral(resourceName: "Test"))

        releaseServices.append(Service1)
        releaseServices.append(Service2)
        releaseServices.append(Service3)

        return releaseServices
    }
}

extension ServiceLines: UITableViewDataSource, UITableViewDelegate {
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return ServiceA.count
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let ServiceB = ServiceA[indexPath.row]
        let cell = tableView.dequeueReusableCell(withIdentifier:"ServicesTableViewCell") as! ServicesTableViewCell
        cell.setServices(service: ServiceB)

        return cell
    }

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        func prepareForSegue(segue: UIStoryboardSegue, sender: Any) {

            let vcName = identities[indexPath.row]
            let viewController = storyboard?.instantiateViewController(withIdentifier: vcName)
            self.navigationController?.pushViewController(viewController!, animated: true)

        }

    }

}

单元格填充了正确的数据，但是当我单击模拟器中的单元格时，它不会移动到上面相应的 View Controller ，这是代码。另外，如何将单元格内部填充的特定数据(例如文本和图像资源)移动到相应的 View Controller (我应该将其添加到该特定 View 的每个相应的 swift 文件中，还是更简单的方法)？

Answer 1

首先，您需要确保您的 ViewController 被设置为 tableView 的委托(delegate)。 其次，从 didSelectRow 中删除prepareForSegue。

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    let vcName = identities[indexPath.row]
    let viewController = storyboard?.instantiateViewController(withIdentifier: vcName)
    // Here you can pass the data you need to the new ViewController
    let service = releaseServices[indexPath.row]
    viewController?.service = service 
    // or if you need only the image
    viewController?.serviceImage = service.image
    self.navigationController?.pushViewController(viewController!, animated: true)
}

我假设您的 viewController 中有一个名为“service”或“image”的属性。
