iPhone RGB

September 27, 2010

Below are the macros that we can use for getting UIColor for the given RGB values. This way we need not create a UIColor object explicitly each time.

1. UIColor from RGB with default alpha set to 1.

#define RGB(r, g, b)
    [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:1]

2. UIColor from RGB with the alpha value.

#define RGBA(r, g, b, a)
 [UIColor colorWithRed:r/255.0 green:g/255.0 blue:b/255.0 alpha:a]

3. UIColor from the Hexa color value.

#define UIColorFromRGB(rgbValue)
 [UIColor \ colorWithRed:((float)((rgbValue & 0xFF0000) >> 16))/255.0 \ green:((float)((rgbValue & 0xFF00) >> 8))/255.0 \  blue:((float)(rgbValue & 0xFF))/255.0 alpha:1.0]
