Для воспроизведения аудио я прошел более крупный пост здесь.В результате получается лучшая версия, но:
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
не работает, что приводит к ошибке члена String при .playback.Вот полный код:
import Foundation
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
@IBAction func triggerSample(_ sender: Any) {
playSound()
}
var player: AVAudioPlayer?
func playSound() {
guard let url = Bundle.main.url(forResource: "soundName", withExtension: "mp3") else { return }
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
/* The following line is required for the player to work on iOS 11. Change the file type accordingly*/
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
/* iOS 10 and earlier require the following line:
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileTypeMPEGLayer3) */
guard let player = player else { return }
player.play()
} catch let error {
print(error.localizedDescription)
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
ОБНОВЛЕНИЕ: Решение написано в закомментированных разделах выше: Для этого используйте следующий playSound () для Xcode 9.2:
func playSound() {
guard let url = Bundle.main.url(forResource: "MWSTW_Bowie", withExtension: "mp3") else { return }
do {
player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
guard let player = player else { return }
player.play()
} catch let error {
print(error.localizedDescription)
} //end of do/catch
} // end of playSound()
