- (void)viewDidLoad { [super viewDidLoad]; NSArray *dirPath=NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES); NSString *docPath=[dirPath objectAtIndex:0]; NSString *filePath=[docPath stringByAppendingPathComponent:@"test1.wav"]; _url=[NSURL URLWithString:filePath]; NSDictionary *recordSettings=[NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:AVAudioQualityMin], AVEncoderAudioQualityKey, [NSNumber numberWithInt:16], AVEncoderBitRateKey, [NSNumber numberWithInt:2], AVNumberOfChannelsKey, [NSNumber numberWithFloat:44100.0], AVSampleRateKey, nil]; NSError *error; //AVAudioRecorder *recorder; //AVAudioPlayer *player; _player=[[AVAudioPlayer alloc] initWithContentsOfURL:_url error:&error]; _recorder=[[AVAudioRecorder alloc] initWithURL:_url settings:recordSettings error:nil]; if (error) { NSLog(@"%@",[error localizedDescription]); }else{ [_recorder prepareToRecord]; } }

调试的时候显示_player的值为nil，还有报错： The operation couldn’t be completed. (OSStatus error 2003334207.)我没在网上找到答案。
