Make HRBrightnessSlider Animated When Moving

[Gabe Rozenberg]

It looks a lot better. I've added this to my current project. Played around with all the animation duration, this works the best.

• (void)updateCursor {
  CGFloat brightnessCursorX = (1.0f - (self.brightness.floatValue - self.brightnessLowerLimit.floatValue) / (1.0f - self.brightnessLowerLimit.floatValue));
  if (brightnessCursorX < 0) {
  return;
  }
  CGPoint point = CGPointMake(brightnessCursorX * _controlFrame.size.width + _controlFrame.origin.x, _brightnessCursor.center.y);
  [UIView animateWithDuration:0.1
  delay:0
  options:UIViewAnimationOptionCurveEaseIn
  animations:^
  {
  _brightnessCursor.center = point;
  _brightnessCursor.color = self.color;
  }
  completion:^(BOOL finished)
  {

      }];
  

  }
