테이블 셀을 클릭하여 여러 배열에서 두 번째보기 컨트롤러로 데이터 보내기

Question

오디오 제목이 나열된 테이블이 있습니다. 제목을 클릭하고 오디오 제목, 그림, 설명 및 재생 버튼을 표시하는 두 번째보기 컨트롤러로 이동합니다.

각 관련 데이터를 모두 보유한 4 개의 배열을 만들었지 만 두 번째보기 컨트롤러에서 imageView 및 단추를 사용하여 테이블의 행이 무엇으로 변경되는지 알 수 없습니다.

let audioTitile = ["Bubbling Pools", "March Of Faith"] 

let audioImage = ["1.png", "2.png"] 

let desc = ["The stench of life fills the air. Viscous fluid bubbles to the surface in great exhortations of gas and moisture. Something about these pools is familiar..", 
      "The devoted stream into the distance. The dust from their sandaled feet blocks out the sun for miles around. There's no stopping them. They believe."] 

public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

     return audioTitle.count 
    } 

    public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

     let cell = UITableViewCell(style: UITableViewCellStyle.default, reuseIdentifier: "Cell") 

     cell.textLabel?.text = audioTitle[indexPath.item] 

     return cell 
    } 

    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
     performSegue(withIdentifier: "segue", sender: audioTitle[indexPath.row]) 
    } 

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
     let temp = segue.destination as! SecondViewController 

     temp.titleLabel.text = audioTitle[0] // need to replace [0] with ? 
     // temp.artworkImage.image = audioImage[0] This Code is wrong 
     temp.descriptionLabel.text = desc[0] // need to replace [0] with ? 


    } 

    @IBOutlet weak var tableView: UITableView! 

    override var preferredStatusBarStyle: UIStatusBarStyle { 
     return .lightContent 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 

    } 
} 

제 2의보기 컨트롤러 코드 : 당신은 어떤 방법으로 배열을 포장한다

import UIKit 
import AVFoundation 

class SecondViewController: UIViewController { 

    @IBOutlet weak var titleLabel: UILabel! 
    @IBOutlet weak var artworkImage: UIImageView! 
    @IBOutlet weak var descriptionLabel: UILabel! 
    @IBOutlet weak var playButton: UIButton! 

    override var preferredStatusBarStyle: UIStatusBarStyle { 
     return .lightContent 
    } 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view. 
    } 

    @IBAction func playButtonPressed(_ sender: Any) { 

     playAudio() 

    } 

    var player: AVAudioPlayer? 

    func playAudio() { 
     let url = Bundle.main.url(forResource: "2_Bubbling_Pools.mp3", withExtension: "mp3")! 

     do { 
      player = try AVAudioPlayer(contentsOf: url) 
      guard let player = player else { return } 

      player.prepareToPlay() 
      player.play() 
     } catch let error { 
      print(error.localizedDescription) 
     } 
    } 

} 

Answer 1

여기

는 첫 번째보기 컨트롤러 내 코드의 샘플입니다. 여러 방법으로 배열을 전송할 수 있지만 가장 올바른 방법은 구조체 또는 클래스를 만드는 것입니다. 이 같은 구조체를 추가

struct Audio { 
var title: String 
var imageName: String 
var descr: String } 

을 먼저의 ViewController에, 초기화 배열 :이처럼 SecondVC을

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return audios.count 
} 

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { 

    let cell = UITableViewCell() 
    let audio = audios[indexPath.row] 
    cell.textLabel?.text = audio.title 
    return cell 
} 

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) { 
    let audio = audios[indexPath.row] 

    performSegue(withIdentifier: "segue", sender: audio) 

} 

override func prepare(for segue: UIStoryboardSegue, sender: Any?) { 
    if segue.identifier == "segue" { 

     let audio = sender as! Audio 
     let destinationVC = segue.destination as! SeconViewController 
     destinationVC.selectedAudio = audio 
    } 
} 

을 변경 :

let audios = [Audio(title: "Bubbling Pools", imageName: "1.png", descr: "The stench of life fills the air. Viscous fluid bubbles "), 
      Audio(title: "March Of Faith", imageName: "2.png", descr: "The stench of life fills the air. Viscous fluid bubbles ")] 

은 다음과 같이 당신의 FirstVC을 변경

class SecondViewController: UIViewController { 

@IBOutlet weak var titleLabel: UILabel! 
@IBOutlet weak var artworkImage: UIImageView! 
@IBOutlet weak var descriptionLabel: UILabel! 
@IBOutlet weak var playButton: UIButton! 

var selectedAudio: Audio! 

override var preferredStatusBarStyle: UIStatusBarStyle { 
    return .lightContent 
} 

override func viewDidLoad() { 
    super.viewDidLoad() 


    // CONFIGURE LABELS HERE USING selectedAudio 

} 

}
