Convert HEX code to RGB

To use hex code in UIColor, use the below macro.

#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]

//Then use any Hex value

self.view.backgroundColor = UIColorFromRGB(0xD2691E);
