i'm trying out uisearchcontroller ios 8 right now. when click cell, push segue , show view controller. however, search controller/bar still there on next controller. also, notice status bar background white, while should grey searchbar background color grey. there miss?

this codes used initialise search controller

override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.      searchcontroller = uisearchcontroller(searchresultscontroller: nil)     searchcontroller.searchresultsupdater = self     searchcontroller.hidesnavigationbarduringpresentation = false     searchcontroller.dimsbackgroundduringpresentation = false     searchcontroller.searchbar.sizetofit()     tableview.tableheaderview = searchcontroller.searchbar }
