Hide Custom Cell in TableView - ios

Question

I have the following implementation, where I am adding a footerview as a customcell. However, if there is no content, I do not want to show the last cell, if there is I want to show it.
In my current implementation, it always displays the last cell.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.adminOrderElements count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return adminOrderElements[section].products.count + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}

There is one option that you can make cellHeight to 0.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(CHECK_IF_NO_CONTAIN)
return 0;
return 40;// Normal height as you want
}

I think you can add condition in else clause like if certain condition is met then you want to display this cell other wise not...
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else //Here add your condition here if you have content for the section like I think this condition might work [adminOrderElements[indexPath.section].notes length]>0
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}

Its quite simple with UITableView delegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (dataObjects.count == 0){
return 0;
}
return dataObjects.count;
}
