How to use UIStepper

You should ignore the ivars. They will not help you.

The UIStepper has a value property that you can query to figure out what the current value is. So your method could simply be:

- (IBAction)valueChanged:(UIStepper *)sender {  double value = [sender value];  [label setText:[NSString stringWithFormat:@"%d", (int)value]];}

UIStepper returns Double value, for swift version do this:

@IBAction func stepperValue(sender: UIStepper) {    print("the stepper value is :\(sender.value)")}

Take the outlet of UIStepper:

@property (strong, nonatomic) IBOutlet UIStepper *stepper;

In viewDidLoad Method:

self.stepper.wraps=YES;

if YES, value wraps from min <-> max. default = NO

 self.stepper.autorepeat=YES;

if YES, press & hold repeatedly alters value. default = YES

Set the initial value to 0.

NSUInteger value= self.stepper.value;self.label.text= [NSString stringWithFormat:@"%02lu",(unsigned long)value];

Set the Maximum value

self.stepper.maximumValue=50;

Take the action of UIStepper:

- (IBAction)valueDidChanged:(UIStepper *)sender {//Whenever the stepper value increase and decrease the sender.value fetch the curent value of stepper        NSUInteger value= sender.value;        self.label.text= [NSString stringWithFormat:@"%02lu",value];}
