self.slider.maximumValue = 255.0;[self.slider setMaxFractionDigitsDisplayed:0];self.slider.popUpViewColor = [UIColor colorWithHue:0.55 saturation:0.8 brightness:0.9 alpha:0.7];self.slider.font = [UIFont fontWithName:@"Menlo-Bold" size:22];self.slider.textColor = [UIColor colorWithHue:0.55 saturation:1.0 brightness:0.5 alpha:1];

NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];[formatter setNumberStyle:NSNumberFormatterPercentStyle];[self.slider setNumberFormatter:formatter];self.slider.popUpViewAnimatedColors = @[[UIColor purpleColor], [UIColor redColor], [UIColor orangeColor]];self.slider.font = [UIFont fontWithName:@"Futura-CondensedExtraBold" size:26];
