Answer 1

I think this is a very nice way to get the rgb representation of any UIColor*, which already has a convenience method for retaining it´s components.

-(CGColorRef)CGColorRefFromUIColor:(UIColor*)newColor {
     CGFloat components[4] = {0.0,0.0,0.0,0.0};
     [newColor getRed:&components[0] green:&components[1] blue:&components[2]        alpha:&components[3]];
     CGColorRef newRGB = CGColorCreate(CGColorSpaceCreateDeviceRGB(), components);
     return newRGB;
}
