ios - Using UISearchController to display search results and keyboard covers bottom rows/sections in UITableView -

there uisearchcontroller displays search results in uitableview split alphabetical sections , corresponding rows based on contacts name.

when there search result displays few contacts larger uitableview keyboard displayed, bottom rows , sections covered keyboard.

what best way increase uitableview content height when displaying filtered search result contacts @ bottom can scrolled , become visible user not covered ios keyboard anymore?

i using swift 3.1 , uisearchresultsupdating delegate updatesearchresults method display filtered results.

you need take care when keyboard appears/disappears , set tableview's contentinset accordingly.

in tableviewcontroller class create 2 functions responders keyboard events:

func keyboardwillshow(notification: nsnotification) {     if let keyboardsize = notification.userinfo?[uikeyboardframebeginuserinfokey] as? cgrect {         let contentinsets = uiedgeinsets(top: 0, left: 0, bottom: keyboardsize.height, right: 0)         self.tableview.contentinset = contentinsets     } }  func keyboardwillhide(notification: nsnotification) {     self.tableview.contentinset = uiedgeinsets.zero } 

and register/deregister responders in viewdidload , deinit:

override func viewdidload() {     super.viewdidload()     ...      // register responders     notificationcenter.default.addobserver(self, selector: #selector(self.keyboardwillshow), name: nsnotification.name.uikeyboardwillshow, object: nil)     notificationcenter.default.addobserver(self, selector: #selector(self.keyboardwillhide), name: nsnotification.name.uikeyboardwillhide, object: nil)  }  deinit {     notificationcenter.default.removeobserver(self) }
