How can I retain the editing in the tableView of the search result with UISearchDisplayController?

Question

I want to search a table in editing mode, but when I type a letter the variable tableView.editing is changed to NO. And when I cancel the search, the tableView.editing return to YES. I'd like to retain the editing YES in the result of the search.

I put breakpoint in several methods. Until the filterContentForSearchText method, the variable is YES, but in the cellForRowAtIndexPath, it is NO.

Image of the table in editing mode just before type a letter in the search bar.
