它不断给我错误：
错误域=AVFoundationErrorDomain代码=-11814“无法记录”
我不确定问题是什么？我试图在拍照后计数器达到 1 时录制声音。
static int counter;
//counter will always be zero it think unless it is assigned.
if (counter == 0){
dispatch_async([self sessionQueue], ^{
// Update the orientation on the still image output video connection before capturing.
[[[self stillImageOutput] connectionWithMediaType:AVMediaTypeVideo] setVideoOrientation:[[(AVCaptureVideoPreviewLayer *)[[self previewView] layer] connection] videoOrientation]];
// Flash set to Auto for Still Capture
[AVCamViewController setFlashMode:AVCaptureFlashModeAuto forDevice:[[self videoDeviceInput] device]];
// Capture a still image.
[[self stillImageOutput] captureStillImageAsynchronouslyFromConnection:[[self stillImageOutput] connectionWithMediaType:AVMediaTypeVideo] completionHandler:^(CMSampleBufferRef imageDataSampleBuffer, NSError *error) {
if (imageDataSampleBuffer)
{//[AVCaptureSession snapStillImage];
NSData *imageData = [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageDataSampleBuffer];
UIImage *image = [[UIImage alloc] initWithData:imageData];
[[[ALAssetsLibrary alloc] init] writeImageToSavedPhotosAlbum:[image CGImage] orientation:(ALAssetOrientation)[image imageOrientation] completionBlock:nil];
}
NSLog(@"i");
}];
});
if (!_audioRecorder.recording)
{
//start recording as part of still image
_playButton.enabled = NO;
_stopButton.enabled = YES;
[_audioRecorder record];
for(int i=0;i<1000;i++)
{
//do nothing just counting
}
//stop the recording
}
}
else if (counter == 1)
{
[self recordForDuration:5];
}
}
这个错误是因为你使用模拟器，你需要使用设备
