iOS Question Why is "0xFF000000" equal to -16777216?
Hi everyone I'm using hex numbers to be comfortable with colors... I needed to add the Alpha channel to RGB color code.. for example dim rgb_color as int = 0xFF0000 dim rgba_color as int = rgb_color + 0xFF000000 this code does not work because "0xFF000000" is recognized as -16777216, do you...- Mike1970
