A slider is used to select a value from a range of values.

Important Properties

  • continuous
  • maximumValue
  • minimumValue
  • value

Add custom methods addSlider and sliderChanged

-(IBAction)sliderChanged:(id)sender{
    NSLog(@"SliderValue %f",mySlider.value);
}
-(void)addSlider{
    mySlider = [[UISlider alloc] initWithFrame:CGRectMake(50, 200, 200, 23)];
    [self.view addSubview:mySlider];
    mySlider.minimumValue = 10.0;
    mySlider.maximumValue = 99.0;
    mySlider.continuous = NO;
    [mySlider addTarget:self action:@selector(sliderChanged:) 
    forControlEvents:UIControlEventValueChanged];
}

Modify viewDidLoad in ViewController.m as follows

(void)viewDidLoad
{
   [super viewDidLoad];
   [self addSlider];
}
