Slider miss place for the value

[fantasticatif]

On setting minValue something other than zero. Slider positioning get wrong.
On going through your code in -layoutSubviews method you are not calculating percentage correctly. I fixed it
with following change
CGFloat leftValuePercentage = (self.leftValue - self.minValue)/oneHundredPercent;
CGFloat rightValuePercentage = (self.rightValue - self.minValue)/oneHundredPercent;
