using AVSystemController in iPhone App

I want to reduce the ringing volume of iPhone programmatically, I came to know that it is possible with AVSystemController, But I know, it is a private method. If I use it, will apple reject the app or please suggest me the alternative way

- (void) setSystemVolumeLevelTo:(float)newVolumeLevel
{
    Class avSystemControllerClass = NSClassFromString(@"AVSystemController");
    id avSystemControllerInstance = [avSystemControllerClass performSelector:@selector(sharedAVSystemController)];

    NSString *soundCategory = @"Ringtone";

    NSInvocation *volumeInvocation = [NSInvocation invocationWithMethodSignature:
                                  [avSystemControllerClass instanceMethodSignatureForSelector:
                                   @selector(setVolumeTo:forCategory:)]];
    [volumeInvocation setTarget:avSystemControllerInstance];
    [volumeInvocation setSelector:@selector(setVolumeTo:forCategory:)];
    [volumeInvocation setArgument:&newVolumeLevel atIndex:2];
    [volumeInvocation setArgument:&soundCategory atIndex:3];
    [volumeInvocation invoke];
}

Possible yes, apple will reject it. Here is the link that will tell you how to do this.[link2

Update:

[[MPMusicPlayerController applicationMusicPlayer] setVolume:setvalue];

Check theselink link also. You cannot change the ringer volume programmatically.

Try this code

float value = 0.5;//this should be between 0.0 to 1.0

[[MPMusicPlayerController applicationMusicPlayer] setVolume: value];

Using any kind of private method there is the change of Apple rejecting your app. Since the public iOS SDk does not allow you to change the ringer volume, you will not be able to this from your app.
