Question

I have a table view with sections.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
        return numberHigherThen0;
}

in cellForRowAtIndexPath method I setup my rows according to section

- (UITableViewCell *)tableView:(UITableView *)aTableView
        cellForRowAtIndexPath:(NSIndexPath *)indexPath {
   if (0 == indexPath.section) {
       //setup rows
   } esle {
     //setup rows
   }
}

numbers of sections and rows in sections changes dynamically. But numbers of sections always > 0. So in cellForRowAtIndexPath indexPath.section == 0 there will be always this case, right ? But some times cellForRowAtIndexPath didn’t pass case indexPath.section == 0 !!! Why ? When it can be true ? When cellForRowAtIndexPath can start count sections from 1 ?

Update:
section 2 has no rows

Answer 1

In numberOfSectionsInTableView: you specify the number of sections – however, the sections are numbered from 0.

So if you return 3 in your numberOfSectionsInTableView you will have three sections – section 0, section 1, and section 2.
