获取本地音频文件地址：
NSString *songsDirectory=MUSIC_FILE_ALL;//沙盒地址 NSBundle *songBundle=[NSBundle bundleWithPath:songsDirectory]; NSString *bundlePath=[songBundle resourcePath]; NSArray *arrMp3=[NSBundle pathsForResourcesOfType:@"mp3" inDirectory:bundlePath]; for (NSString *filePath in arrMp3) { [self.wMp3URL addObject:filePath]; }解析音频文件属性：
