Thread1：EXC_BAD_ACCESS（代码= 1，地址= 0X48）AVAudioPlayer（Swift）

Question

每次按下button Thread1:EXC_BAD_ACCESS(code=1, address = 0X48)我都会得到一个Thread1:EXC_BAD_ACCESS(code=1, address = 0X48) 。 我检查了我的连接，我的mp3文件“歌曲”是正确的。 我不确定是什么问题。 我的按钮工作得很好，但它只是AVAudioPlayer (var Player)不允许按钮崩溃程序并返回错误。 任何帮助将不胜感激（我是Swift的初学者）。

import UIKit
import AVFoundation

class ViewController: UIViewController {

    var player:AVAudioPlayer = AVAudioPlayer()

    @IBAction func play(_ sender: UIButton) {

        player.play()
    }

    @IBAction func pause(_ sender: UIButton) {
        player.pause()
    }

    @IBAction func replay(_ sender: UIButton) {
       player.currentTime = 0
    }


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

            do{
                let audioPath = Bundle.main.path(forResource: "song", ofType: "mp3")
                try player = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL)
            }
            catch{
                //error
            }                                        
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }            
}

Answer 1

我写了相同的代码项目，但没有任何错误

我的代码

var player:AVAudioPlayer = AVAudioPlayer()
lazy var btn: UIButton = {
    var btn = UIButton.init(frame: CGRect.init(x: 20, y: 20, width: 60, height: 60))
    btn.backgroundColor = .red

    btn.addTarget(self, action: #selector(ViewController.play), for: .touchUpInside)
    return btn
}()
override func viewDidLoad() {
    super.viewDidLoad()

    self.view.addSubview(btn)
    do{
        let audioPath = Bundle.main.path(forResource: "song", ofType: "mp3")
        try player = AVAudioPlayer(contentsOf: NSURL(fileURLWithPath: audioPath!) as URL)
    }
    catch{
        //error
    }
}
func play() {
    player.play()
}

请检查一下这个问题

1.玩家是否在主线程上运行？

2.song.mp3存在且可以播放

3.故事板是否存在冲突
