Swift中AVFoundation的简单使用

import AVFoundation
class ViewController: UIViewController,AVAudioPlayerDelegate{

    var audioPlayer:AVAudioPlayer?
    //AVAudioPlayerDelegate
    public func audioPlayerDidFinishPlaying(_ player: AVAudioPlayer, successfully flag: Bool){
        print("播放完成")
    }
    override func viewDidLoad() {
        super.viewDidLoad()
        DispatchQueue.global().async {[weak self]in
            let mainBoundle = Bundle.main
            let filePath = mainBoundle.path(forResource: "music", ofType: "mp3")
            if let path = filePath{
                let fileData = NSData.init(contentsOfFile: path)
                do{
                    try self!.audioPlayer = AVAudioPlayer.init(data: fileData! as Data)
                    
                    self!.audioPlayer?.delegate = self;
                    if self!.audioPlayer!.prepareToPlay() && self!.audioPlayer!.play(){
                        print("success")
                    }else{
                        print("error")
                    }
                }catch{
                     print("catch：error")
                }
               
            }
        }
        
    }
}
