How to use UIStepper

Question

I am trying to work with UIStepper to increment or decrement an integer, but both \"-\" and \"+\" increase the integer! How can I recognize the \"+\" and \"-\

Answer 1

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];
}
