Question

Can I have the number of rows dynamically?
I’m trying to remove a tableView section header and I don’k know how… and I’ve taught that a solution would be to change the number of sections.

Right now my numberOfSectionsInTableView looks like:

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
        return 2;
}

and

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    beTribesAppDelegate *appDelegate = [UIApplication sharedApplication].delegate;

    switch (section) {
        case 0:
            return [appDelegate.firstArray count];
        case 1:
            return [appDelegate.secondArray count];    
        default:
            return 0;
    }
}

setting the title section like this:

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{ 
    sectionTitles = [[NSMutableArray alloc] init];

        [sectionTitles addObject:@"firstSection"];
        [sectionTitles addObject:@"secondSection"];
    NSString *sectionText = [sectionTitles objectAtIndex:section];
    return sectionText;
}

I am not sure to understand the question as the answer seems trivial: just change the implementation to return some dynamic value and you are done, right?

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return self.nbSections;
}

Where nbSections is a property to which you will assign the value you want so you can change it at any time you want. So what’s the matter then?

PS: Of course, call [tableView reloadData] to recompute the content of your tableView and make the new value being taken into account obviously… maybe that’s what you were missing?
