Body
I've been looking for the answer for 2 days, but I can't seem to get it right... I have an example app that records audio and video from the device using a AVCaptureSession and a AVCaptureMovieFileOutput. When I start recording I call: <pre><code>[self.movieFileOutput startRecordingToOutputFileURL:outputURL recordingDelegate:self]; </code></pre> And it starts recording to the file. If I press the button again it stops recording <pre><code>[self.movieFileOutput stopRecording]; </code></pre> Everything works well, but when I enter background (incoming call or HOME press) I get an error in the delegate method: didFinishRecordingToOutputFileAtURL My desired action should be saving / completing the file on entering the background. If I call stopRecording on "applicationDidEnterBackground" it will enter background before the applicationDidEnterBackground is called. On entering the active state it is called.... and generates an error and leaves a corrupted movie file... It seems that it hasn't got enough time to save the file. What am I missing here? This is my Error <code>Error Domain=AVFoundationErrorDomain Code=-11818 "Recording Stopped" UserInfo=0x17594e20 {NSLocalizedRecoverySuggestion=Stop any other actions using the recording device and try again., NSUnderlyingError=0x175d3500 "The operation couldn’t be completed. (OSStatus error -16133.)", NSLocalizedDescription=Recording Stopped}</code> <pre><code>AVErrorSessionWasInterrupted = -11818 </code></pre>

1. COI've also tried the Apple AVDemo app and it also gives the same Error. It seems that the error is thrown anyway. The difference is that in Apples' code they have time to execute extensive code using UIBackgroundTaskIdentifier

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.
