How to return a nil CGFloat?

Question

I'd like to return nil to tableView:heightForFooterInSection: but that's not allowed. Is there a way to return nil as a CGFloat?

Why are you doing this?
I'm testing how a tableView will behave with a mix of Titles and Views as sectionFooters. For one footer I need to use a custom view, but for another footer I have 3 or 4 sentences of text and I like how the system styles it and sizes the footer to fit. But as soon as I implement heightForFooterInSection (which is required by viewForFooterInSection), the footer with the title no longer auto-resizes to fit the given text. I'm trying to avoid building a custom view for the straight text.

There's no such thing as nil for primitive values. You could try returning 0.0f, but I don't know how UITableView responds to that. It may just hide the view entirely. Presumably if you want to return a custom view for one footer, you need to return a custom view for all footers.
