My first foray in Quartz and I'm having some problems, obviously missing
something.
Given the following code in a subclass of UIButton:
UIColor *baseColor = self.backgroundColor;
CGColorRef cgColor = baseColor.CGColor;
int32_t model = CGColorSpaceGetModel(CGColorGetColorSpace(cgColor));
const CGFloat *colorComponents = CGColorGetComponents(cgColor);
float red = 0.0;
float green = 0.0;
float blue = 0.0;
float alpha = 0.0;
if (model == kCGColorSpaceModelRGB)
{
red = colorComponents[0];
green = colorComponents[1];
blue = colorComponents[2];
alpha = colorComponents[3];
}
It doesn't matter which background color I choose for the button in Interface
Builder, all the main 3 color components are always 1. Yes, I double-checked
that I had a valid reference to my button, I just don't get it.
Anybody sees what I'm doing wrong?
