UITableView Reusing Content from Different Sections - ios

Question

My TableView has three different sections. Section 0 is for photo uploads its virtually empty until a user uploads a photo. However, my tableview is reusing cells from section 1 in section 2 and i'm not sure why. Here is the code below. Any help is greatly appreciated.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"cell";
if (indexPath.section == 0) {
UploadsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = [[UploadsCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.tag = indexPath.row;
cell.delegate = self;
cell.imageInfo = [_uploads objectAtIndex:indexPath.row];
[cell setCellInfo];
cell.backgroundColor = [UIColor redColor];
return cell;
}
else{
id object;
if (indexPath.section == 1) {
object = [self cacheObjectAtIndexPath:indexPath];
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
}
if (indexPath.section == 2) {
object = [self objectAtIndexPath:indexPath];
}
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath withMobiObject:(MobiObject *)object{
static NSString *CellIdentifier = #"Cell";
StylesCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil) {
cell = (StylesCell*)[[StylesCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (object) {
[cell setObject:object];
}
return cell;
}

You should first begin by making your methods a bit more readable. Since you've asked me for it, I've rewritten one of your larger methods to use a switch when returning the correct configuration for cells based on their section.
As for your actual problem, it's very likely associated with the following lines returning the configuration for Section 1:
id object = [self cacheObjectAtIndexPath:indexPath];
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
As well as the other line returning configuration for Section 2:
id object = [self objectAtIndexPath:indexPath];
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
I'm not sure exactly what these methods return, so it's hard to say what exactly about them is returning duplicate cells.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
switch (indexPath.section) {
case 0:
// Section is Zero
UploadsCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
cell.tag = indexPath.row;
cell.delegate = self;
cell.imageInfo = [_uploads objectAtIndex:indexPath.row];
[cell setCellInfo];
[cell setBackgroundColor:[UIColor redColor]];
return cell;
case 1:
// Section is One
id object = [self cacheObjectAtIndexPath:indexPath];
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
case 2:
// Section is Two
id object = [self objectAtIndexPath:indexPath];
return [self tableView:tableView cellForRowAtIndexPath:indexPath withObject:object];
default:
// Section is neither of the aforementioned sections.
break;
}
}
