Question

I’m developing an iPhone application with latest SDK and XCode 4.5.2.

On a ViewController I have two UITableView. Both use the same UITableViewDataSource. My question is about static NSString* CellIdentifier;.

Can I do the following?

- (UITableViewCell* )tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString* CellIdentifier;
    SingletonGlobalVars* singleton = [SingletonGlobalVars sharedInstance];

    if ([tableView isEqual:shopsList])
    {
        CellIdentifier = @"ShopCell";
    }
    else
    {
        CellIdentifier = @"ProductCell";
    }

   [ ... ]
}

I need to change CellIdentifier but I don’t know if I can do this with a static variable.

Your code would work, but using a static variable does not make sense in your case. Just use a local variable. Note also that you can compare the pointers to UITableView directly, it is not necessary to use isEqual here.

NSString* cellIdentifier;
if (tableView == shopsList)
{
   cellIdentifier = @"ShopCell";
}
else
{
   cellIdentifier = @"ProductCell";
}

(I assume that shopsList is one of the table views.)
