帮我生成一个可以在iPhone中运行的swift中的storyboar录音和播放程序

好的，我可以为您提供一个简单的录音和播放程序。请按照以下步骤操作：

1. 创建一个新的 Xcode 项目，选择 Single View App 模板，语言选择 Swift。

2. 在 Main.storyboard 中添加两个按钮（录音和播放）和一个标签，用于显示录音和播放状态。

3. 在 ViewController.swift 文件中添加以下代码：

import UIKit
import AVFoundation

class ViewController: UIViewController, AVAudioRecorderDelegate, AVAudioPlayerDelegate {

    @IBOutlet weak var statusLabel: UILabel!
    
    var audioRecorder: AVAudioRecorder?
    var audioPlayer: AVAudioPlayer?

    override func viewDidLoad() {
        super.viewDidLoad()
        setupRecorder()
    }
    
    func setupRecorder() {
        let audioSession = AVAudioSession.sharedInstance()
        do {
            try audioSession.setCategory(AVAudioSession.Category.playAndRecord)
            try audioRecorder = AVAudioRecorder(url: getFileURL(), settings: getAudioSettings())
            audioRecorder?.delegate = self
            audioRecorder?.prepareToRecord()
        } catch {
            print("Error setting up audio recorder: \(error.localizedDescription)")
        }
    }
    
    func getFileURL() -> URL {
        let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)[0]
        let audioURL = documentsDirectory.appendingPathComponent("recording.caf")
        return audioURL
    }
    
    func getAudioSettings() -> [String: Any] {
        let settings = [
            AVFormatIDKey: NSNumber(value: kAudioFormatAppleLossless),
            AVEncoderAudioQualityKey: AVAudioQuality.max.rawValue,
            AVEncoderBitRateKey: 320000,
            AVNumberOfChannelsKey: 2,
            AVSampleRateKey: 44100.0
        ]
        return settings
    }
    
    @IBAction func startRecording(_ sender: UIButton) {
        if audioRecorder?.isRecording == false {
            let audioSession = AVAudioSession.sharedInstance()
            do {
                try audioSession.setActive(true)
                audioRecorder?.record()
                statusLabel.text = "Recording..."
            } catch {
                print("Error starting recording: \(error.localizedDescription)")
            }
        }
    }
    
    @IBAction func stopRecording(_ sender: UIButton) {
        if audioRecorder?.isRecording == true {
            audioRecorder?.stop()
            let audioSession = AVAudioSession.sharedInstance()
            do {
                try audioSession.setActive(false)
                statusLabel.text = "Recording stopped"
            } catch {
                print("Error stopping recording: \(error.localizedDescription)")
            }
        }
    }
    
    @IBAction func playRecording(_ sender: UIButton) {
        if audioPlayer?.isPlaying == false {
            do {
                try audioPlayer = AVAudioPlayer(contentsOf: getFileURL())
                audioPlayer?.delegate = self
                audioPlayer?.play()
                statusLabel.text = "Playing..."
            } catch {
                print("Error playing audio: \(error.localizedDescription)")
            }
        }
    }
    
    func audioRecorderDidFinishRecording(_ recorder: AVAudioRecorder, successfully flag: Bool) {
        if flag {
            statusLabel.text = "Recording saved"
        } else {
            statusLabel.text = "Recording failed"
        }
    }
    
    func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool) {
        if flag {
            statusLabel.text = "Playback finished"
        } else {
            statusLabel.text = "Playback failed"
        }
    }
}

这段代码包括了以下内容：

- 创建 AVAudioRecorder 和 AVAudioPlayer 实例来处理录音和播放
- 设置录音的 URL 和参数
- 设置录音和播放的按钮动作
- 显示录音和播放状态的标签
- 实现 AVAudioRecorderDelegate 和 AVAudioPlayerDelegate 来处理录音和播放完成后的事件

4. 运行应用程序并在iPhone中测试录音和播放功能。

请注意，这只是一个简单的示例，您可以根据您的需求进行修改和扩展。同时，您需要确保在应用程序的 Info.plist 文件中添加了麦克风和音频播放权限，否则应用程序将无法访问麦克风或播放音频文件。
