You will need to listen for value changes on the slider. You can set this up in interface builder or in code.

//Add event for valueChanged in viewDidLoad
[self.slider addTarget:self 
                action:@selector(sliderValueChanged:) 
      forControlEvents:UIControlEventValueChanged];

...

-(void)sliderValueChanged:(id)sender
{
    self.textField.text = [NSString stringWithFormat:@"%d", 
                             (int)(slider.value * 99) + 1];
}
