refer a following code.

- (void)viewDidLoad
{
    UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(0,0,300,40)];
    [slider addTarget:self action:@selector(sliderHandler:) forControlEvents:UIControlEventValueChanged];
    slider.minimumValue = 0.f;
    slider.maximumValue = 1.0f;
    slider.value = [[UIScreen mainScreen] brightness];
    [[self view]addSubview:slider];

    [super viewDidLoad];
}

- (void)sliderHandler:(UISlider *)sender
{
    //NSLog(@"value:%f", sender.value);
    [[UIScreen mainScreen] setBrightness:sender.value];
}
