【问题描述】：
全部。
我在发送数据时遇到问题。
我尝试将数据从AgentDetailVC 发送到AbilitiesDetailsVC。但我不能。我尝试发送的每个数据都是零或空字符串。我设法在AgentListVC之前发送到AgentDetailsVC。你们都可以检查我的代码并帮助我吗？万分感谢。
这是我的AgenListVC。
import UIKit
class AgentListVC: UIViewController {
var agentsReference = ValorantReferenceApp().agents
@IBOutlet var tableView: UITableView!
override func viewDidLoad() {
self.tableView.rowHeight = 100
// tableView.separatorStyle = .none
tableView.delegate = self
tableView.dataSource = self
super.viewDidLoad()
configureNavigationBar()
}
//MARK: - Configure Navigation Bar
func configureNavigationBar() {
self.navigationController?.navigationBar.prefersLargeTitles = true
if var textAttributes = navigationController?.navigationBar.titleTextAttributes {
textAttributes[NSAttributedString.Key.foregroundColor] = UIColor.red
navigationController?.navigationBar.titleTextAttributes = textAttributes
}
}
}
//MARK: - Table View Methods
extension AgentListVC: UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return agentsReference.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell1", for: indexPath) as! AgentCellVC
let agent = agentsReference[indexPath.row]
cell.agentNameLAbel.text = agent.name
cell.agentImageview.image = agent.iconAgent
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "toSecondVC", sender: nil)
// tableView.deselectRow(at: indexPath, animated: true)
}
//MARK: - Prepare Segue
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
let destinationVC = segue.destination as! AgentDetailVC
if let indexPath = tableView.indexPathForSelectedRow {
let agent = agentsReference[indexPath.row]
destinationVC.agentDetailVariables.choosenFlagImage = agent.agentFlagImage
destinationVC.agentDetailVariables.choosenAgentIconImage = agent.iconAgent
destinationVC.agentDetailVariables.choosenAgentType = agent.type.rawValue
destinationVC.agentDetailVariables.choosenAgentName = agent.name
destinationVC.choosenAgentAbilities = agent.abilities
destinationVC.agentDetailVariables.choosenAgentAbilitiesImages = agent.agentAbilitiesImage
destinationVC.choosenAgentVideoLink = agent.skillAbilitiesLink
}
}
}
这是我的AgentDetailVC。
import UIKit
class AgentDetailVC: UIViewController {
@IBOutlet var typeLabel: UILabel!
@IBOutlet var characterImageView: UIImageView!
@IBOutlet var flagImageView: UIImageView!
@IBOutlet var tableView: UITableView!
@IBOutlet var agentTypeImageView: UIImageView!
var agentDetailVariables = AgentDetailVariables()
var agentsReference = ValorantReferenceApp().agents
var choosenAgentAbilities = [String]()

var choosenAgentVideoLink = [String]()
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
viewLoad()
print(choosenAgentAbilities)
}
//MARK: - ViewLoad Function.
func viewLoad() {
flagImageView.image = agentDetailVariables.choosenFlagImage
characterImageView.image = agentDetailVariables.choosenAgentIconImage
typeLabel.text = agentDetailVariables.choosenAgentType
title = agentDetailVariables.choosenAgentName
tableView.rowHeight = 65
tableView.separatorStyle = .none
agentTypeImageView.image = UIImage(named: "\(agentDetailVariables.choosenAgentType)")
// print(agentDetailVariables.choosenAgentVideoLink)
}
}
//MARK: - TableView Methods
extension AgentDetailVC : UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return choosenAgentAbilities.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell2", for: indexPath) as! AgentDetailsCellVC
let agentAbilities = choosenAgentAbilities[indexPath.row]
let skillImages = agentDetailVariables.choosenAgentAbilitiesImages[indexPath.row]
print(agentAbilities)
cell.skillNameLabel.text = agentAbilities
cell.skillImageView.image = skillImages
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
performSegue(withIdentifier: "toYoutubeVideos", sender: nil)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "toYoutubeVideos" {
let destinationVC = segue.destination as! AbilitiesDetailsViewController
if let indexPath = tableView.indexPathForSelectedRow {
let agent = agentsReference[indexPath.row]
let link = choosenAgentVideoLink[indexPath.row]
print(link)
destinationVC.agentAbilitiesVideoURL = link
destinationVC.choosenAgentSkillName = choosenAgentAbilities[indexPath.row]
}
}
}
}
这是我的AbilitiesDetailsViewController
import UIKit
import AVKit
import AVFoundation
import MediaPlayer
import MobileCoreServices
import YoutubePlayer_in_WKWebView
class AbilitiesDetailsViewController: UIViewController, AVPlayerViewControllerDelegate {
@IBOutlet var skillDetailsLabel: UILabel!
@IBOutlet var skillNameLabel: UILabel!
@IBOutlet var heroIconImageView: UIImageView!
var agentAbilitiesVideoURL = ""
var choosenAgentSkillName = ""
override func viewDidLoad() {
skillNameLabel.text = choosenAgentSkillName
super.viewDidLoad()
//playAbilitiesVideos()
}
@IBAction func playVideoUsingURL(_ sender: Any) {
playGlobalVideo()
}
func playGlobalVideo() {
guard let videoURL = URL(string: agentAbilitiesVideoURL ?? "sad") else {
return
}
let player = AVPlayer(url: videoURL)
let vc = AVPlayerViewController()
vc.player = player
present(vc, animated: true) {
player.play()
}
}
func playAbilitiesVideos() {
let player = AVPlayer(url: URL(string: "https://assets.contentstack.io/v3/assets/bltb6530b271fddd0b1/bltf4e7a6525fe6ec42/625f2c7cfd9afd4b1fe300ee/C-Prowler_video.mp4")!)
let controller = AVPlayerViewController()
present(controller, animated: true) { }
controller.player = player
addChild(controller)
view.addSubview(controller.view)
controller.view.frame = CGRect(x: 50 , y: 50, width: 300, height: 300)
controller.player = player
controller.showsPlaybackControls = true
player.isClosedCaptionDisplayEnabled = false
player.play()
}
}
这是我的结构。
struct Agent: Hashable{
let name: String
let type: AgentType
let origin: String
let abilities: [String]
let iconAgent : UIImage
let agentFlagImage : UIImage
let agentAbilitiesImage: [UIImage]
let skillAbilitiesLink: [String]
}
enum AgentType:String{
case controller = "Controller"
case sentinel = "Sentinel"
case initiator = "Initiator"
case duelist = "Duelist"
}
这是我的代理人。

【问题讨论】：
-
2个问题：如果你评论
performSegue(withIdentifier: "toSecondVC", sender: nil)，它会进入下一个屏幕吗？你在if let indexPath = tableView.indexPathForSelectedRow中传递了if吗？ -
我评论它 segue 代码行并且不进入下一个屏幕。
