    <p>I've got a button the user tap to start recording and tap again to stop. When it stop I want the recorded voice 'echo' back so the user can hear what was recorded. This works fine the first time. If I hit the button for the third time, it starts a new recording and when I hit stop it crashes with EXC_BAD_ACCESS.</p> <pre><code>- (IBAction) readToMeTapped { if(recording) { recording = NO; [readToMeButton setTitle:@"Stop Recording" forState: UIControlStateNormal ]; NSMutableDictionary *recordSetting = [[NSDictionary alloc] initWithObjectsAndKeys: [NSNumber numberWithFloat: 44100.0], AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey, [NSNumber numberWithInt: 1], AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityMax], AVEncoderAudioQualityKey, nil]; // Create a new dated file NSDate *now = [NSDate dateWithTimeIntervalSinceNow:0]; NSString *caldate = [now description]; recordedTmpFile = [NSURL fileURLWithPath:[[NSString stringWithFormat:@"%@/%@.caf", DOCUMENTS_FOLDER, caldate] retain]]; error = nil; recorder = [[ AVAudioRecorder alloc] initWithURL:recordedTmpFile settings:recordSetting error:&amp;error]; [recordSetting release]; if(!recorder){ NSLog(@"recorder: %@ %d %@", [error domain], [error code], [[error userInfo] description]); UIAlertView *alert = [[UIAlertView alloc] initWithTitle: @"Warning" message: [error localizedDescription] delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; return; } NSLog(@"Using File called: %@",recordedTmpFile); //Setup the recorder to use this file and record to it.

I thought it may have something to do with releasing memory but I've been careful. Have I missed something?</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.
