在TableView中播放不同的声音
在TableView中播放不同的声音
提问于 2016-11-14 05:29:06
现在，当我单击这些表视图单元格中的按钮时，我想播放不同的声音。我在编程方面是个新手，我不知道该怎么做。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一行中的按钮。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: "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
}

首先，您需要向按钮添加操作，并为该按钮分配一些标记，以确定哪个按钮是cellForRowAt上clicked.do一些代码
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

如果你的声音不超过30秒，我建议使用AudioToolbox。这个框架专门为此目的设计了功能。
Objective-C
- 导入框架
#通过创建SystemSoundID like为您的声音导入
- make引用
@property (assign，非原子) soundIDOne;
- Prepare SystemSoundID you'r sonds in the sonds
AudioServicesPlaySystemSound(_soundIDOne);
- If %u需要完成-添加处理程序
AudioServicesAddSystemSoundCompletion(_soundIDOne，NULL，NULL，playSoundFinished，NULL)；playSoundFinished playSoundFinished (SystemSoundID声音，空*数据){//在此处执行操作}
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")有关更多信息，请查看here
如果您想使用AVFoundation，代码将如下所示：
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()此外，如果你有短持续时间的文件，这个延迟可以是非常小的，甚至没有，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
当然我不能告诉你关于AVFoundationQueuePlayer的事情，这也是一个很好的解决方案。Here是苹果的示例链接
