Set Hex value to UIColor - iPhone SDK

When you need to set basic colors to things in Objective-C, it's really easy:

//This works, but come on...
cell.textColor = [UIColor grayColor];

However, if you want to be more specific normally you need to get the RGBA for the color and set it that way. That's time consuming especially if the color may be tweaked several times before the final is settled upon. In flash we can just use  Hex. Now, with this little  macro, you can too & it's a HUGE time saver:

#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]

- (UITableViewCell *)tableView:(UITableView *)tv cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
    if (nil == cell) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"cell"] autorelease];
    }
    cell.textColor = UIColorFromRGB(0x333333);
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    cell.text = @"Testing 1 2 3";
}
