iOS - Sliders

Use of Sliders

Sliders are used to choose a single value from a range of values.

Important properties

continuous
maximumValue
minimumValue
value

Important method

- (void)setValue:(float)value animated:(BOOL)animated

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];
}

Update viewDidLoad in ViewController.m as follows

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

Output

Now when we run the application we'll get the following output.

On dragging the slider the output will be as follows and will print the new value in the console.
