iOSオーディオ開発AVAudioPlayerの使用、音響再生AudioServicesPlaySystemSoundの使用

オーディオ開発AVAudioPlayerの使用AVAudioPlayerはiOSシステムが持参したローカルmp 3ファイルを再生できるクラスです(注意:ローカルのみ再生可能)参考:http://www.jianshu.com/p/589999e534611,先導入庫AVFoundation/AVFoundation.hエージェントAVAudioPlayerDelegate 2を行い、再生するmp 3ファイルをプロジェクトにインポートするには、使用するグローバル変数@property(nonatomic,strong)AVAudioPlayer*playerを定義する.property (weak, nonatomic) IBOutlet UIProgressView *Progress; @property (weak, nonatomic) IBOutlet UILabel *CurrentTime; @property (weak, nonatomic) IBOutlet UILabel *countTime; @property (nonatomic,strong)NSArray *sourceArray;//歌曲配列@property(nonatomic,copy)NSString*currentsong;@property (nonatomic,strong)NSTimer *timer;//タイマ
