ios - 在TableView中播放不同的声音

Question

现在，当我单击这些表格 View 单元格内的按钮时，我想播放不同的声音。我对编程非常陌生，我不知道如何做到这一点。我已经为我的声音文件创建了一个数组，但我不知道如何将它们分配给连续的这些按钮。非常感谢您的帮助

这是我的代码

import UIKit
import AVFoundation

class ViewController6: UIViewController, UITableViewDataSource, UITableViewDelegate {

    var audioPlayer = AVAudioPlayer()

    override func viewDidLoad() {
        super.viewDidLoad()

    }

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


//Array of Rifles

    var arrayOfRifles = ["AK47", "AUGA1", "FAMAS", "G36K", "K1A", "K2", "M4A1", "M4Silencer", "M16", "M60", "MicroGALIL", "QBZ95", "RPK", "ScarHeavy", "Scarlight", "SG552", "TAR21", "Tommy", "Type89", "XM8"]
    var buttonDataRifles = ["AK47", "AUGA1", "FAMAS", "G36K", "K1A", "K2", "M4A1", "M4Silencer", "M16", "M60", "MicroGALIL", "QBZ95", "RPK", "ScarHeavy", "Scarlight", "SG552", "TAR21", "Tommy", "Type89", "XM8"]

    var soundsArray: [NSURL] = [
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "AK47", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "AUGA1", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "FAMAS", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "G36K", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "K1A", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "K2", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M4A1", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M4Silencer", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M16", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "M60", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "MicroGALIL", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "QBZ95", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "RPK", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "ScarHeavy", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "ScarLight", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "SG552", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "TAR21", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "Tommy", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "Type89", ofType: "mp3")!),
    NSURL(fileURLWithPath: Bundle.main.path(forResource: "XM8", ofType: "mp3")!)
    ]




//Functions for tableView

    //Cell - For Rifles

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

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell6 = tableView.dequeueReusableCell(withIdentifier: "cell6", for: indexPath) as! ViewControllerTableViewCell6

        cell6.myImage.image = UIImage(named: arrayOfRifles[indexPath.row] + ".jpg")
        cell6.myButton.setTitle(buttonDataRifles[indexPath.row], for: UIControlState.normal)
        return (cell6)

        cell6.myButton.tag = indexPath.row
        cell6.myButton.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)}

    @IBAction func buttonAction(_ sender: UIButton) {

        print("Button tapped")
        let tapedIndex = sender as UIButton
        let getUrl = soundsArray[tapedIndex] as! NSURL


    }

如果你的声音不超过 30 秒，我建议使用 AudioToolbox。该框架为此目的专门设计了功能。

Objective-C

1. 导入框架

   #import <AudioToolbox/AudioToolbox.h>
   

2. 通过创建 SystemSoundID 为您的声音提供引用

   @property (assign, nonatomic) SystemSoundID soundIDOne;
   

3. 从一开始就准备好你的儿子

   AudioServicesCreateSystemSoundID ( (__bridge CFURLRef)([[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Swish" ofType:@"wav"]]), &_soundIDDone);
   

4. 播放声音

   AudioServicesPlaySystemSound(_soundIDOne);
   

5. 如果您需要完成 - 添加处理程序

   AudioServicesAddSystemSoundCompletion(_soundIDOne, NULL, NULL, playSoundFinished, NULL);
   
   
   void playSoundFinished (SystemSoundID sound, void *data) {
       //do stuff here
   }
   

swift 2.2

    import AudioToolbox

    private var soundID:SystemSoundID?

    if let filePath = NSBundle.mainBundle().pathForResource("name", ofType: "type") {
        let pathToResource = NSURL(fileURLWithPath: filePath)
        soundID = 0
        if var soundID = soundID {
            AudioServicesCreateSystemSoundID(pathToResource, &soundID)
        }
    }

    if var soundID = soundID {
        AudioServicesPlaySystemSound(soundID)
    }

    //or create extension

    extension SystemSoundID {
        static func playSound(soundName: String, fileExtension: String) {
            var soundID: SystemSoundID = 0
            if let filePath =  NSBundle.mainBundle().pathForResource(soundName, ofType: fileExtension) {
                let pathToResource = NSURL(fileURLWithPath: filePath)
                AudioServicesCreateSystemSoundID(pathToResource, &soundID)
                AudioServicesPlaySystemSound(soundID)
            }
        }
    }

    //and usage

    SystemSoundID.playSound("soundFileName", fileExtension: "extension")

如果你想使用 AVFoundation 代替，代码如下:

    import AVFoundation

    var audioPlayer = AVAudioPlayer() //create player

    //create all path to y'r resources

    var path:[NSURL] = []

    if let filePath =  NSBundle.mainBundle().pathForResource("soundName", ofType: "fileExtension") {
        let pathToResource = NSURL(fileURLWithPath: filePath)
        path.append(pathToResource)
    }

    //in the very start
    do {
        if let selectedPath = path.first {
            audioPlayer = try AVAudioPlayer(contentsOfURL: selectedPath)
            audioPlayer.prepareToPlay()
        }
    } catch {
        print(error)
    }

    audioPlayer.play()

在这种情况下，由于 AVAudioPlayer 需要 prepareToPlay，因此在播放声音之前您可能会出现一些延迟，为了确保您可以播放声音，您需要对 AVPlayer 进行更复杂的设置并观察玩家status，喜欢的可以引用this link 。另外，如果您的文件持续时间较短，那么这种延迟可能会非常小甚至不存在，无论如何，对于我来说，由于上述原因，这不是播放大量声音文件的首选方式

因为我不能告诉你AVFoundationQueuePlayer，这也是一个很好的解决方案。 Here是苹果示例链接
