Question

i have this that works:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Item *objItem = [[self fetchedResultsController] objectAtIndexPath:indexPath];
CustomCell *cell = nil;
cell = [self.tableView dequeueReusableCellWithIdentifier:identifierLONG];
[self configureCell:cell atIndexPath:indexPath tableView:tableView];

}

And i want to do something like this:

- (void)configureCell:(TimelineTextoFotoCell *)cell atIndexPath:(NSIndexPath *)indexPath tableView:(UITableView *)tableView{

Item *objItem = [[self fetchedResultsController] objectAtIndexPath:indexPath];
 cell.txtNota.text = objItem.nota;

 if ([cell.txtNota.text sizeWithFont:cell.txtNota.font constrainedToSize:CGSizeMake(cell.txtNota.frame.size.width, 1000.f)].height/cell.txtNota.font.pointSize < 2.0) {
        cell = [tableView dequeueReusableCellWithIdentifier:identifierSHORT];
    } else {
    //should remain dequeueReusableCellWithIdentifier:identifierLONG....
    }

//setup cell the same, for both cases.
}

It doesnt work. The cell always uses the dequeueReusableCellWithIdentifier:identifierLONG, and i checked the line cell = [tableView dequeueReusableCellWithIdentifier:identifierSHORT]; gets executed. I need to change the identifier based on the fetched objectAtIndexPath:indexPath

From what I can see, you always request a cell with identifierLONG in cellForRowAtIndexPath. Then you pass that over to configureCell, where you optionally try to replace that cell with one with identifierSHORT. I guess that might be too late because you already dequeued one with identifierLONG. To be honest, I never tried something like that, so I can’t tell for sure whether that’s the cause of your problem.

Did you already try something like this in cellForRowAtIndexPath:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    Item *objItem = [[self fetchedResultsController] objectAtIndexPath:indexPath];
    CustomCell *cell = nil;

    if (<<ToBeReplacedWithSomeConditionWhichOnlyUsesobjItem>>) {
        cell = [tableView dequeueReusableCellWithIdentifier:identifierSHORT];
    } else {
        cell = [tableView dequeueReusableCellWithIdentifier:identifierLONG];
    }
    [self configureCell:cell atIndexPath:indexPath tableView:tableView];

}
