UITableViewCell has a different background color under iOS4 and iOS5. I wanted to support iOS4 for my app and I need to change the cell’s background color on error and then change it back again. I couldn’t change it back again on both iOS4 and iOS5. Hence this hacky class method

+ (UIColor *)defaultBackgroundColor:(UITableViewCell *)inCell
{
    
    if (NULL == FFUtiltiesBackgroundCellColor) {
        // iOS 4 and iOS5 have different color backgrounds for tabbed group dialogs
        // hence this gross hack. Must put it in a utility class someday.
        // see http://stackoverflow.com/questions/8405644/what-is-the-default-background-color-of-a-uitableviewstylegrouped-styled-uitable
        //
        //backgroundCellColor = usernameCell.contentView.backgroundColor;
        NSString *version = [[UIDevice currentDevice] systemVersion];
        NSString *firstLetter = [version substringToIndex:1]; 
        
        if (firstLetter == @"4") {
            FFUtiltiesBackgroundCellColor = [UIColor whiteColor];
        } else {
            FFUtiltiesBackgroundCellColor = [UIColor colorWithRed:(0xF7/255.0)green:(0xF7/255.0)  blue:(0xF7/255.0) alpha:1.0];
        }
    }

    return FFUtiltiesBackgroundCellColor;
}

Hey, it works. I don’t use this anymore, I no longer see a business case for support iOS4 for my apps. Then again, clients apps can make the case, so I’m certainly not deleting the code!
