    text
    copied!<p>I am trying to setup a basic controller that will record user audio input(voice). However, the AVAudioRecorder's prepareToRecord method is failing and I can't figure out why. I have setup the audio session in my app delegate and I do not receive an errors when I instantiate the AVAudioRecorder instance:</p> <p>// App delegate snippet</p> <pre><code>AVAudioSession* audioSession = [AVAudioSession sharedInstance]; NSError* audioSessionError = nil; [audioSession setCategory: AVAudioSessionCategoryPlayAndRecord error: &amp;audioSessionError]; if (audioSessionError) { NSLog (@"Error setting audio category: %@", [audioSessionError localizedDescription]); } else { NSLog(@"No session errors for setting category"); } [audioSession setActive:YES error:&amp;audioSessionError]; if (audioSessionError) { NSLog (@"Error activating audio session: %@", [audioSessionError localizedDescription]); } else { NSLog(@"no session errors for setActive"); } </code></pre> <p>// VIEW DID LOAD IN RECORDERCONTROLLER</p> <pre><code>- (void)viewDidLoad { self.navigationItem.title = [NSString stringWithFormat:@"%@", [[MyAppDelegate loadApplicationPlist] valueForKey:@"recorderViewTitle"]]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismiss)]; [self alertIfNoAudioInput]; [self createAVAudioRecorder]; minutesSecondsFormatter = [[SimpleMinutesSecondsFormatter alloc] init]; currentTimeUpdateTimer = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(updateAudioDisplay) userInfo:NULL repeats:YES]; [super viewDidLoad]; } </code></pre> <p>// CREATE AVAUDIORECORDER</p> <pre><code>- (NSError *)createAVAudioRecorder { NSError *recorderSetupError = nil; [audioRecorder release]; audioRecorder = nil; NSString *timestamp = [NSString stringWithFormat:@"%d", (long)[[NSDate date] timeIntervalSince1970]]; NSString *destinationString = [[MyAppDelegate getAppDocumentsDirectory] stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.caf", timestamp]]; NSLog(@"destinationString: %@", destinationString); NSURL *destinationUrl = [NSURL fileURLWithPath: destinationString]; audioRecorder = [[AVAudioRecorder alloc] initWithURL:destinationUrl settings:[[AVRecordSettings sharedInstance] getSettings] error:&amp;recorderSetupError]; if (recorderSetupError) { UIAlertView *cantRecordAlert = [[UIAlertView alloc] initWithTitle:@"Can't record" message:[recorderSetupError localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [cantRecordAlert show]; [cantRecordAlert release]; return recorderSetupError; } else { NSLog(@"no av setup error"); } if ([audioRecorder prepareToRecord]) { recordPauseButton.enabled = YES; audioRecorder.delegate = self; } else { NSLog(@"couldn't prepare to record"); } NSLog (@"recorderSetupError: %@", recorderSetupError); return recorderSetupError; } </code></pre>
