How do we change the iPhone lighting through UISlider?



  • How to change the iPhone illumination by UISlider?



  • Create a slider:

    UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(0, 100, 320, 100)];
    [slider addTarget:self action:@selector(changeBrightness:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:slider];
    slider.value = [UIScreen mainScreen].brightness; //начальное значение
    

    Modify the

    - (void)changeBrightness:(UISlider*)sender
    {
        [UIScreen mainScreen].brightness = sender.value;
    }
    

    It only works on the device, not the simulator.
