//  dictionarytableviewcontroller.swift     import uikit      class dictionarytableviewcontroller: uitableviewcontroller, uisearchresultsupdating      {         var searchcontroller:uisearchcontroller!         var searchresults:[dictionary] = []          var dictionaries:[dictionary] =[          dictionary (word: "grocery1", definition: "this grocery1 definition"),          dictionary (word: "grocery2", definition: "this grocery2 definition"),          dictionary (word: "grocery3", definition: "this grocery3 definition"),          dictionary (word: "grocery4", definition: "this grocery4 definition"),         ]         override func viewdidload() {             super.viewdidload()              searchcontroller = uisearchcontroller(searchresultscontroller: nil)             tableview.tableheaderview = searchcontroller.searchbar             searchcontroller.searchresultsupdater = self             searchcontroller.dimsbackgroundduringpresentation = false         }             override func didreceivememorywarning() {             super.didreceivememorywarning()         }          // mark: - table view data source          override func numberofsectionsintableview(tableview: uitableview) -> int {             return 1         }          override func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {              if searchcontroller.active {                 return searchresults.count             } else {                 return dictionaries.count             }         }          override func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {              let cellidentifier = "cell"             let cell = tableview.dequeuereusablecellwithidentifier(cellidentifier, forindexpath: indexpath) as! dictionarytableviewcell              let dictionary = (searchcontroller.active) ? searchresults[indexpath.row]: dictionaries[indexpath.row]              // configure cell...             cell.wordlabel.text = dictionary.word             return cell         }          override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {             if segue.identifier == "showdictionarydetail" {                 if let indexpath = tableview.indexpathforselectedrow {                     let destinationcontroller = segue.destinationviewcontroller as! dictionarydetailviewcontroller                     destinationcontroller.dictionary = (searchcontroller.active) ? searchresults[indexpath.row] : dictionaries[indexpath.row]                 }             }         }              func updatesearchresultsforsearchcontroller(searchcontroller:                 uisearchcontroller) {                     if let searchtext = searchcontroller.searchbar.text {                         filtercontentforsearchtext(searchtext)                         tableview.reloaddata()                     }             }              func filtercontentforsearchtext(searchtext: string) {                 searchresults = dictionaries.filter({ (dictionary:dictionary) -> bool in                     let wordmatch = dictionary.word.rangeofstring(searchtext, options:                         nsstringcompareoptions.caseinsensitivesearch)                     return wordmatch != nil                 })}} 

when using searchcontroller, can deactivate when leaving screen. insert self.searchcontroller.active = false

you can @ viewwilldisappear or prepareforsegue. this

override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {     if segue.identifier == "showdictionarydetail" {         if let indexpath = tableview.indexpathforselectedrow {             let destinationcontroller = segue.destinationviewcontroller as! dictionarydetailviewcontroller             destinationcontroller.dictionary = (searchcontroller.active) ? searchresults[indexpath.row] : dictionaries[indexpath.row]             self.searchcontroller.active = false         }     } }
