Subclass UISlider

[stuartjmoore]

Since it's a slider, subclassing UISlider would allow you to use it in other libraries. I've think I've done it with (plus some other obvious changes):

#pragma mark - UISlider Override

- (float)value
{
  return (float)self.angle;
}

- (UIImage*)currentThumbImage
{
  return nil;
}
- (UIImage*)currentMaximumTrackImage
{
  return nil;
}
- (UIImage*)currentMinimumTrackImage
{
  return nil;
}
