AVAudioRecorder Record method returns NO at random times

Question

I’m currently developing an app which supports in-app audio recording. The user can get a standard tableview of locally saved audio files he/she have already recorded throug

Answer 1

Is contentURL always the same or do you generate a new one each time?

Also could you try explicitly calling prepareToRecord before record and checking whether it succeeds or not?

Answer 2

Before the recording is started an audio session should be initialized:

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory :AVAudioSessionCategoryPlayAndRecord error:&err];
if(err){
   NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
   return;
}
err = nil;
[audioSession setActive:YES error:&err];
if(err){
   NSLog(@"audioSession: %@ %d %@", [err domain], [err code], [[err userInfo] description]);
   return;
}
