Question

There are some section in the table that does not contain any data and would like to hide that section.

How to do this?

Answer 1

You can also return the number of records that do contain data from the numberofSectionsInTableView: method and use a switch(indexPath.section) where you let the empty records 'fall through' to the next switch, like:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    switch (indexPath.section) {
        case 0:
            return 
;
            break;

        case 1:
            if(firstRecordHasData){
                return ;
                break;
            }

        case 2:
            if(secondRecordHasData){
                return ;
                break;
            }

        case 3:
            return ;
            break;

        default:
            return ;
            break;
    }   
}

I was struggling with this for a while because I had to leave out sections in the middle of a grouped table. Tried with setting cell-, header- and footer heights to 0.0 but that didn't work. Couldn't just delete certain sections because of the called methods depending on the selected row. This was going to be a huge if..else if...else if with multiple callings of subroutines. Glad I thought of the good old switch method, maybe it helps you as well :-)
