同一个文件路径，不同初始化方法，存在audioPlayer初始化失败的情况
NSURL *contentURL = [NSURL fileURLWithPath:_fileUrl];
self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:contentURL error:&error];
NSData *data = [NSData dataWithContentsOfURL:contentURL];
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:data error:&error];
// initWithContentsOfURL:初始化失败
Error Domain=NSOSStatusErrorDomain Code=1685348671 "(null)"

iOS使用AVAudioPlayer播放data音频文件遇到的问题
- 检查发现，code= 2003334207的可能原因是：跟文件的检测有关、在下载文件时不完整，所以创建失败了！
- 可能不是没有本地化完成的问题，直接播放即可
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:vData fileTypeHint:AVFileTypeWAVE error:&error];//AVFileTypeWAVE 为音频格式
//替换
NSError *error;
self.audioPlayer = [[AVAudioPlayer alloc] initWithData:vData error:&error];
