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

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]];
}
