UITableView: Mixing static and dynamic cells
- by AlexR
I am trying to mix dynamic and static cells in a grouped table view: I would like to get two sections with static cells at the top followed by a section of dynamic cells (please refer to the screenshot below). I have set the table view contents to static cells.
I designed the static cells in Interface Builder and gave them identifiers related to their section and row: "section0static0", "section0static1", "section1static0" and "section1static1". I named the dynamic cell "section2dynamic".
My delegate methods, in which I am trying to return the correct cell identifier (static or dynamic) are as follows:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
switch (section) {
case 0:
return 2;
break;
case 1:
return 2;
break;
case 2:
return 0;
break;
default:
break;
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"";
if (indexPath.section <= 1) CellIdentifier = [NSString stringWithFormat:@"section%istatic%i",indexPath.section,indexPath.row];
else CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
return cell;
}
Edit
Based on AppleFreak's advice I have changed my code as follows:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell;
if (indexPath.section <= 1) { // section <= 1 indicates static cells
cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
} else { // section > 1 indicates dynamic cells
CellIdentifier = [NSString stringWithFormat:@"section%idynamic",indexPath.section];
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
}
return cell;
}
However, my app crashes with error message
Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'UITableView dataSource
must return a cell from tableView:cellForRowAtIndexPath:'
for section 0 and row 0. The cell returned from cell = [super tableView:tableView cellForRowAtIndexPath:indexPath] for section 0 and row 0 is nil.
What is wrong with my code? Could there be any problems with my outlets? I haven't set any outlets because I am subclassing UITableViewController and supposedly do not any outlets for tableview to be set (?). Any suggestions on how to better do it?
