我使用AVAudioRecorder它順利拍攝,我可以播放或得到保存的文件我使用下面的代碼來初始化AVAudioRecorderAVAudioRecorder指定
NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:kAudioFormatMPEG4AAC], AVFormatIDKey,
[NSNumber numberWithInt:AVAudioQualityLow], AVEncoderAudioQualityKey,
[NSNumber numberWithInt:16], AVEncoderBitRateKey,
[NSNumber numberWithInt: 1], AVNumberOfChannelsKey,
[NSNumber numberWithFloat:16000], AVSampleRateKey,
nil];
NSArray *searchPaths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentPath_ = [searchPaths objectAtIndex: 0];
NSString *pathToSave = [documentPath_ stringByAppendingPathComponent:[self dateString]];
self.pathfinal = pathToSave;
NSURL *url = [NSURL fileURLWithPath:pathToSave];
recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error];
if (!recorder)
{
return NO;
}
recorder.delegate = self;
recorder.meteringEnabled = YES;
if (![recorder prepareToRecord])
{
return NO;
}
if (![recorder record])
{
return NO;
}
錄製音頻,但我的一些客戶是當它們停止記錄(它將保存在磁盤上的步驟)時,它不會保存創建文件的任何內容,但每次記錄時都沒有數據。
但是,當使用不同的iPhone它不是一個問題。 iPhone有2GB可用硬盤空間。任何想法可能是什麼原因造成的?
