Splitting Sections. 1 year, 2 months ago #1

Hi again. I have this code that splits a tableview into two sections, one with a name field, and the second with everything else..

- (void)tableViewModel:(SCTableViewModel *)tableViewModel 
	detailViewWillAppearForSectionAtIndex:(NSUInteger)index 
	withDetailTableViewModel:(SCTableViewModel *)detailTableViewModel
{
	NSLog(@"%s", __FUNCTION__);
 
	//************* Set a tag that is equivalent to the model's level in the heirarchy (used later to identify the model)
	detailTableViewModel.tag = tableViewModel.tag + 1;
 
	//************* Set the delegate for the detail model so that delegate methods would be called
	detailTableViewModel.delegate = self;
 
	if(tableViewModel.tag == 0)  // main model
	{
		SCTableViewSection *verbSection = [detailTableViewModel sectionAtIndex:0];
		SCTableViewCell *nameCell = [verbSection cellAtIndex:0];  
		SCTableViewCell *transCell = [verbSection cellAtIndex:1];
 
		// Create new section
		SCObjectSection *newSection = [SCObjectSection section];
		newSection.commitCellChangesLive = FALSE;  // allow user to cancel changes by tapping Cancel
		[newSection addCell:nameCell];
		[newSection	addCell:transCell];
		[detailTableViewModel insertSection:newSection atIndex:0];
 
		// Remove the nameCell from the original section
		[verbSection removeCellAtIndex:0];
		[verbSection removeCellAtIndex:1];
	}
}
 
- (void)tableViewModel:(SCTableViewModel *)tableViewModel 
	detailViewWillAppearForRowAtIndexPath:(NSIndexPath *)indexPath 
	withDetailTableViewModel:(SCTableViewModel *) detailTableViewModel
{
	[self tableViewModel:tableViewModel detailViewWillAppearForSectionAtIndex:indexPath.section
		withDetailTableViewModel:detailTableViewModel];
}

I have mucked around with it, but I would like to know how to have two or three elements in the first section, and the remainder in the second..

Thanks !!

Hi David,

Your code actually has a bug in these couple of lines:

 
...
[verbSection removeCellAtIndex:0];
[verbSection removeCellAtIndex:1];
...

When you remove the cell at index zero, the next cell to be removed is now at index zero too, and not index one. So the code should be:

 
...
[verbSection removeCellAtIndex:0];
[verbSection removeCellAtIndex:0];
...

Or if you'd like to avoid the confusion:

 
...
[verbSection removeCellAtIndex:1];
[verbSection removeCellAtIndex:0];
...

Hope this helps!
