UISlider's value changes to values outside of range

I am trying to implement a UISlider that has a minimum of 1 and a maximum of 10. I set up an IBOutlet for the slider and an IBAction for when the slider's value changes. Here is my code:

//scale is the slider, and scaleValue is a label that displays the slider's value.
- (IBAction)scaleChanged
{
    scaleValue.text = [NSString stringWithFormat:@"%d", scale.value];
    NSLog(scaleValue.text);
}

The problem is what NSLog gives me:

You get the idea. Now, I know the slider's value is a float and not an integer, but the strange thing is that it was actually working fine before, when I had the maximum set instead at 50. Now, though, even if I set the maximum back to 50, it still prints this out. What is going on?

your NSLog is not following the right syntax, write like this

 NSLog(@"%@",scaleValue.text);

instead NSLog(scaleValue.text);

Try this

- (IBAction)scaleChanged
{
    scaleValue.text = [NSString stringWithFormat:@"%.2f", scale.value];
    NSLog(scaleValue.text);
}
