打在TableView中

不同的聲音現在我要玩不同的聲音，當我點擊這些表視圖細胞內的按鈕。我在編程方面非常新，我無法弄清楚如何做到這一點。我爲我的聲音文件創建了一個數組，但我不知道如何將它們分配給一行中的這些按鈕。非常感謝您的幫助

，這是我的代碼

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")!),

     let getUrl = soundsArray[tapedIndex] as! NSURL 


    } 


}

所有你需要添加動作按鈕並指定一些標記到該按鈕，以確定哪一個是clicked.do一些代碼的第一在cellForRowAt

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

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

func buttonAction(sender: UIButton!) 
{ 
print("Button tapped") 
let tapedIndex = sender as! UIButton 
let getUrl = buttonDataRifles[tapedIndex.tag] as! NSURL 
}

究竟是什麼意思，「分配一些標籤到該按鈕，以確定哪個被點擊」？ –

我們必須在這裏指定cell6.myButton.tag = indexPath.row作爲標記，所以只要我們只點擊一行按鈕，所以我們可以識別哪個按鈕單擊我們可以播放該行的歌曲。 – Bucket

let getUrl = soundsArray [tapedIndex] as！ NSURL 我在這一行發生錯誤，說'不能用'UIButton'類型的索引來下標'NSURL'類型的值 –

如果u'r聽起來不多於30秒，我建議使用AudioToolbox。該框架爲此目的而專門設計了功能。

Objective-C的

進口框架，爲您的聲音
```
#import <AudioToolbox/AudioToolbox.h> 
```

提及與像

@property (assign, nonatomic) SystemSoundID soundIDOne;

創建SystemSoundID準備找你sonds在很begginning

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

播放聲音

AudioServicesPlaySystemSound(_soundIDOne);

如果妳需要完成 - 添加處理器

AudioServicesAddSystemSoundCompletion(_soundIDOne, NULL, NULL, playSoundFinished, NULL); 


void playSoundFinished (SystemSoundID sound, void *data) { 
    //do stuff here 
}

雨燕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")

更多的外觀here

如果ü要使用AVFoundation代替代碼將是這樣的：

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()

在這種情況下，美國可以，聲音播放，因爲之前得到一些延遲要求prepareToPlay的AVAudioPlayer ，要確保你可以播放聲音，你需要一個更復雜的設置AVPlayer與觀察status播放器，如果你喜歡你可以參考this link。另外，如果你的文件的播放時間很短，這個延遲可能會非常小，甚至無法播放，無論如何，對於我來說這並不是因爲上述原因播放大量聲音文件的首選方式

因爲我無法播放告訴你關於AVFoundationQueuePlayer，這也是很好的解決方案。 Here是蘋果示例鏈接
