    <p>I am trying to record and play video simultaneously. Is this possible with avfoundation? Currently i am able to do it as long as i dont record audio. As soon as i add audio input to AVCaptureSession and restart the whole thing i receive "AVCaptureSessionWasInterruptedNotification" and recording stops. </p> <p>This is how i play video. </p> <pre><code>MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:path]]; [moviePlayer.view setFrame:self.playerView.bounds]; moviePlayer.useApplicationAudioSession=NO; self.player = moviePlayer; [moviePlayer release]; [self.playerView addSubview:player.view]; [player play]; </code></pre> <p>And this is how I record video:</p> <pre><code>NSError *error; AVCamCaptureManager *captureManager = [[AVCamCaptureManager alloc] init]; if ([captureManager setupSessionWithPreset:AVCaptureSessionPresetLow error:&amp;error]) { [self setCaptureManager:captureManager]; AVCaptureVideoPreviewLayer *previewLayer = [[AVCaptureVideoPreviewLayer alloc] initWithSession:[captureManager session]]; self.captureVideoPreviewLayer= previewLayer; UIView *view = [self cameraView]; CALayer *viewLayer = [view layer]; [viewLayer setMasksToBounds:YES]; CGRect bounds = [view bounds]; [captureVideoPreviewLayer setFrame:bounds]; if ([captureVideoPreviewLayer isOrientationSupported]) [captureVideoPreviewLayer setOrientation:AVCaptureVideoOrientationPortrait]; [captureVideoPreviewLayer setVideoGravity:AVLayerVideoGravityResizeAspectFill]; [[captureManager session] startRunning]; [self setCaptureVideoPreviewLayer:captureVideoPreviewLayer]; if ([[captureManager session] isRunning]) { [captureManager setOrientation:AVCaptureVideoOrientationPortrait]; [captureManager setDelegate:self]; [viewLayer insertSublayer:captureVideoPreviewLayer below:[[viewLayer sublayers] objectAtIndex:0]]; NSString *countString = [[NSString alloc] initWithFormat:@"%d", [[AVCaptureDevice devices] count]]; NSLog(@"Device count: %@",countString); } else { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"Failed to start session." delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil]; [alertView show]; [alertView release]; } } else { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Input Device Init Failed" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Okay" otherButtonTitles:nil]; [alertView show]; [alertView release]; } [captureManager release]; if (![[self captureManager] isRecording]) { [[self captureManager] startRecording]; } </code></pre> <p>Where as i am using "AVCamCaptureManager" from apple AVCam sample code.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
