Searchcontroller仅在iOS 11或更高版本上可用

Question

I'm trying to make my app iOS 9 compliant. But I get this error for the navigationItem.searchController :

'searchController' is only available on iOS 11.0 or newer

How can I make this available for iOS 9 without changing every search logic through the app?

Answer 1

You cannot set the navigation item's searchController before iOS 11, but you can certainly use the UISearchController, just as we've done for years. Simply extract the UISearchController's searchBar and put it, yourself, wherever you want it in the interface. If you want it as or in the navigation bar, then put it there. For example, make it the navigation item's titleView .
