    If you want to increase the volume of iphone in a specific app and then reduce it to it's current volume. The following code might get helpful:- (NOTE:Include FrameWork: MediaPlayer.framework )

    -(void)exampleFuctionSample{

    NSLog(@"");

    [self increaseVolume];

    // Code

    [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(reduceVolumeToCurrent) userInfo:nil repeats:NO ]; // Timer will help you delay so that you can play increase volume

    }

    -(void)increaseVolume{

    NSLog(@"Entered Set Volume");

    float currentVolume=[MPMusicPlayerController applicationMusicPlayer].volume;

    NSLog(@"Current volume is %f",[MPMusicPlayerController applicationMusicPlayer].volume);

    float maxVolume = 1.0;

    [[MPMusicPlayerController applicationMusicPlayer] setVolume:maxVolume];

    }

    -(void)reduceVolumeToCurrent{

    NSLog(@"reduceVolumeToCurrent");

    [[MPMusicPlayerController applicationMusicPlayer]setVolume:currentVolume];

    }
