    <p>I'm animating the navigation bar using a timer when recording starts and stopping it when the recording stops (to make it similar to the Voice Memos app).</p> <p>Here is the code</p> <pre><code>//do nav bar animation _navigationImageCount = 0; self.navigationBarTimer = [NSTimer scheduledTimerWithTimeInterval:(2.0 / 28.0) target:self selector:@selector(changeNavigationBarImage:) userInfo:nil repeats:YES]; - (void)changeNavigationBarImage:(NSTimer *)timer { NSMutableArray *navigationBarImages = [NSMutableArray arrayWithArray:@[@"nav_bar_01.png", @"nav_bar_02.png", @"nav_bar_03.png", @"nav_bar_04.png", @"nav_bar_05.png", @"nav_bar_06.png", @"nav_bar_07.png", @"nav_bar_08.png", @"nav_bar_09.png", @"nav_bar_10.png", @"nav_bar_11.png", @"nav_bar_12.png", @"nav_bar_13.png", @"nav_bar_14.png"]]; [navigationBarImages addObjectsFromArray:[[navigationBarImages reverseObjectEnumerator] allObjects]]; NSInteger imageIndex = _navigationImageCount % 28; [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:navigationBarImages[imageIndex]] forBarMetrics:UIBarMetricsDefault]; _navigationImageCount++; } - (void)audioRecorderBeginInterruption:(AVAudioRecorder *)recorder { [recorder stop]; [self.recordingTimer invalidate]; //timer used to update the UI [self.navigationBarTimer invalidate]; } </code></pre> <p>I am saving the recording to a file to a directory named "MyRecordings" under the Library directory and if print the contents of that directory it shows the file, however when I try to print the duration it gives 0.</p> <p>If I try to play the file at that url it gives error code 1685348671 (file invalid).</p> <p>How can the save the first part of the recording be saved properly?</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.
