Draw gradient like UITabBar with tintColor in code

Question

UITabBar by default draws a subtle gradient: I would like to replicate this look and feel in my code with any given tintColor. Just to make it clear: I do not want to set a tintColor on UITabBar (which is possible since iOS 5), I would like to draw the gradient in my own UIView. I know how to draw the gradient, my problem is how to derive the colors for the gradient from the tintColor. I was thinking about getting the brightness of the color and generating the other colors with different brightness-settings, but that doesn't seem to work that well and looks not as good as I would like it to look. I need the code for my open source TabBarController: https://github.com/NOUSguide/NGTabBarController Here's my current code for creating the gradient: ``` UIColor *baseColor = self.tintColor; CGFloat hue, saturation, brightness, alpha; // TODO: Only works on iOS 5 [baseColor getHue:&hue saturation:&saturation brightness:&brightness alpha:&alpha]; // That's the question, how to compute the col…
