Something like this:
id cell = button;
for(; cell && ![cell isKindOfClass:[UITableViewCell class]]; cell = [cell superview]);
When this loop exits you get either the cell or nil indicating that the button is not inside a cell.

Therefore, it’s already implicit in your approach that the view controller doing ‘prepareForSegue:’ knows that the button is in a table view, hence in a cell, hence a subview of the cell. There’s no special-case knowledge involved there.
