unsigned int red = 0, green = 0, blue = 0;

NSRange range = {0, 2};

range.location = 0;

NSString *redString = [hexString substringWithRange:range];

NSScanner *redScanner = [NSScanner scannerWithString:redString];

[redScanner scanHexInt:&red];

range.location = 2;

[greenScanner scanHexInt:&green];

range.location = 4;

NSScanner *blueScanner = [NSScanner scannerWithString:[hexString substringWithRange:range]];

[blueScanner scanHexInt:&blue];

__autoreleasing UIColor *color = [UIColor colorWithRed:red/255.0 green:green/255.0 blue:blue/255.0 alpha:1];

return color;
