出现错误：传递给不带参数的调用的参数

Question

我在 AppDelegate 中收到此错误，但我不确定问题可能是什么。任何帮助表示赞赏，谢谢！

（出现错误的确切行是：“private func loadDetails”部分中的“let detailsViewModel = DetailsJobView(details: details)”）

顺便说一句，错误在（详细信息：详细信息）中的第二个“详细信息”中强调了“d”

我已经在代码中注明了，但可能很难找到。

import UIKit
import Firebase
import CoreLocation
import Moya

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

let window = UIWindow()
let locationService = LocationService()
let homeStoryboard = UIStoryboard(name: "Home", bundle: nil)
let service = MoyaProvider<YelpService.BusinessesProvider>()
let jsonDecoder = JSONDecoder()
var navigationController: UINavigationController?

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    
    // Change color of tab bar items
    UITabBar.appearance().tintColor = .black
    FirebaseApp.configure()

    jsonDecoder.keyDecodingStrategy = .convertFromSnakeCase

    locationService.didChangeStatus = { [weak self] success in
        if success {
            self?.locationService.getLocation()
        }
    }

    locationService.newLocation = { [weak self] result in
        switch result {
        case .success(let location):
            self?.loadJobs(with: location.coordinate)
        case .failure(let error):
            assertionFailure("Error getting the users location \(error)")
        }
    }

    switch locationService.status {
    case .notDetermined, .denied, .restricted:
        let locationViewController = homeStoryboard.instantiateViewController(withIdentifier: "LocationViewController") as? LocationViewController
        locationViewController?.delegate = self
        window.rootViewController = locationViewController
    default:

            .instantiateViewController(withIdentifier: "JobNavigationController") as? UINavigationController
        self.navigationController = nav
        window.rootViewController = nav
        locationService.getLocation()
        (nav?.topViewController as? JobTableViewController)?.delegete = self
    }
    window.makeKeyAndVisible()
    
    return true
}

private func loadDetails(for viewController: UIViewController, withId id: String) {
    service.request(.details(id: id)) { [weak self] (result) in
        switch result {
        case .success(let response):
            guard let strongSelf = self else { return }
            if let details = try? strongSelf.jsonDecoder.decode(Details.self, from: response.data) {

                (viewController as? DetailsJobViewController)?.viewModel = detailsViewModel
            }
        case .failure(let error):
            print("Failed to get details \(error)")
        }
    }
}

private func loadJobs(with coordinate: CLLocationCoordinate2D) {
    service.request(.search(lat: coordinate.latitude, long: coordinate.longitude)) { [weak self] (result) in
        guard let strongSelf = self else { return }
        switch result {
        case .success(let response):
            let root = try? strongSelf.jsonDecoder.decode(Root.self, from: response.data)
            let viewModels = root?.jobs
                .compactMap(JobListViewModel.init)
                .sorted(by: { $0.distance < $1.distance })
            if let nav = strongSelf.window.rootViewController as? UINavigationController,
                let jobListViewController = nav.topViewController as? JobTableViewController {
                jobListViewController.viewModels = viewModels ?? []
            } else if let nav = strongSelf.homeStoryboard
                .instantiateViewController(withIdentifier: "JobNavigationController") as? UINavigationController {
                strongSelf.navigationController = nav
                strongSelf.window.rootViewController?.present(nav, animated: true) {
                    (nav.topViewController as? JobTableViewController)?.delegete = self
                    (nav.topViewController as? JobTableViewController)?.viewModels = viewModels ?? []
                }
            }
        case .failure(let error):
            print("Error: \(error)")
        }
    }
}
}

extension AppDelegate: LocationActions, ListActions {
func didTapAllow() {
    locationService.requestLocationAuthorization()
}

func didTapCell(_ viewController: UIViewController, viewModel: JobListViewModel) {
    loadDetails(for: viewController, withId: viewModel.id)
}
}

这是 @heitormurara 要求的 DetailsJobView：

import UIKit
import MapKit

@IBDesignable class DetailsJobView: CoreView {
@IBOutlet weak var collectionView: UICollectionView?
@IBOutlet weak var pageControl: UIPageControl?
@IBOutlet weak var priceLabel: UILabel?
@IBOutlet weak var hoursLabel: UILabel?
@IBOutlet weak var locationLabel: UILabel?
@IBOutlet weak var ratingsLabel: UILabel?
@IBOutlet weak var mapView: MKMapView?

@IBAction func handleControl(_ sender: UIPageControl) {

}
}

我的猜测是您试图以不正确的方式实例化 UIView 孩子。尝试在不带参数的情况下对其进行初始化，并将您的 details 变量作为公共变量：

let detailsViewModel = DetailsJobView()
detailsViewModel.details = details

另外，您需要在DetailsJobView 中创建变量details：

import UIKit
import MapKit

@IBDesignable class DetailsJobView: CoreView {
  ...

  var details: Details?
