When and how to properly deactivate an audio session?

I got a little lost with AVFoundation and you are my last hope!

I write a training application in which sometimes I play short tips, for example: “Pedal for 10 minutes” or “Good!”

Apple recommends activating the audio session immediately before playing the invitation and always deactivating it after the invitation starts. More than a recommendation, this is really what I want, because I use this option: AVAudioSessionCategoryOptionDuckOthers, and I just want to bite the music player during invitation playback, not earlier, but not after.

I do not know how to achieve this! Since I'm not very sure about deactivating an audio session, my first idea was to use a "while".

Here is my AudioController class:

#import "AudioController.h"

@interface AudioController ()


@property(strong,nonatomic)AVAudioPlayer *audioPlayerGood;

@end


@implementation AudioController

-(id)init
{
    self=[super init];
    if (self) {
        [self configureAudioSession];
        [self preparePlayers];
    }
    return self;
}

-(void)configureAudioSession
{
    self.audioSession = [AVAudioSession sharedInstance];
    NSError *setCategoryError = nil;
    [self.audioSession setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionDuckOthers error:&setCategoryError];

}


-(void)preparePlayers
{
    NSError *initAudioPlayerError = nil;

    NSURL *urlGood = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Correct" ofType:@"caf"]];



    self.audioPlayerGood = [[AVAudioPlayer alloc] initWithContentsOfURL:urlGood error:&initAudioPlayerError];

   if (initAudioPlayerError) {
        NSLog(@"Error in audioPlayer: %@",[initAudioPlayerError localizedDescription]);
    }


    [self.audioPlayerGood prepareToPlay];
 }

-(void)playCorrect
{
    NSError *activationError = nil;
    [self.audioSession setActive:YES error:&activationError];
    [self.audioPlayerGood play];
    NSLog(@"****************Correct played***************");
    while (self.audioPlayerGood.playing) {
        break;
    }
    [self.audioSession setActive:NO error:&activationError];
 }


@end

Then, I initialize the AudioController object in another class, in which I use the playCorrect method:

[self.audioController playCorrect];

But immediately after playing the sound, the debug area prints this text to me:

AVAudioSession.mm:646: - [AVAudioSession setActive: withOptions: error:]: deactivate an audio session with I / O triggering. All input / output operations must be stopped or paused before the audio session is deactivated.

And if in ten seconds I want to play this sound again, it will not work, whereas the playCorrect method should activate the audio session ... Therefore, I don’t know how to deactivate the audio session correctly, and when it happens, if anyone can help with this :)
