POiOS - Overwrite the particular audio recording In specific time

Body
copied!<p>Hi I need to develop an app that can record, play, stop and overwrite audio. I have done the Recording by using <code>AvAudioRecorder</code>:</p> <pre><code>NSDictionary *audioSettings = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithFloat: 44100],AVSampleRateKey, [NSNumber numberWithInt: kAudioFormatLinearPCM],AVFormatIDKey, [NSNumber numberWithInt: 2],AVNumberOfChannelsKey, [NSNumber numberWithInt: AVAudioQualityLow], AVEncoderAudioQualityKey, nil]; self.audioRecorder = [[AVAudioRecorder alloc] initWithURL:audioFileURL settings:audioSettings error:nil]; [sliderTimer invalidate]; [self.audioRecorder record]; sliderTimer = [NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(updateSlider) userInfo:nil repeats:YES]; </code></pre> <p>...and playback is done using <code>AVplayer</code>.</p> <p>But I dont know how to overwrite the recording. This the outline of my overwrite implementation:</p> <ol> <li>Stop Recording</li> <li>Move the slider position to the particular point</li> <li>Then, start recording.</li> </ol> <p>This is the functionality to overwrite the previous recordings.</p> <p>So, As per the steps I have written </p> <pre><code>[self.audioRecorder stop]; [[self audioSlider] setValue:self.audioSlider.value animated:YES]; [self.audioRecorder recordAtTime:self.audioSlider.value forDuration:self.audioSlider.maximumValue]; </code></pre> <p>...but its not working. Instead, they totally re-record the file. Could any body help me for this critical situation.</p>
