UILabel Value .56 Make it 56%

I have a label that is controlled for a UISlider. When I get half way with the slider it shows .50. How can I change that .50 to 50%? Thanks so much!

My slider code: 

- (IBAction) sliderValueChanged:(UISlider *)sender {
    tipPercentLabel.text = [NSString stringWithFormat:@" %.2f", [sender value]];
}
Solution

  • UISlider is a fraction between 0.0 and 1.0.

    So how about something like:

    tipPercentLabel.text = [NSString stringWithFormat:@" %f%%", ([sender value] * 100)];

    The "%%" in the format string indicates a percent character to be printed. I might be a tiny bit off in the format string (maybe cast the multiplied value to an integer and use "%d%%").
