UISearchController won't dismiss searchbar and overlap for iOS 8 Swift

Question

I'm having problem with the UISearchController where if I have text in the searchbar and dismiss the VC it's in, the searchBar won't go away and just remain on screen overlapping everything in other VCs. Then it crashes if you hit the cancel button.

Have tried a few solutions on SO but none have worked. :/

self.resultSearchController = ({
        let controller = UISearchController(searchResultsController: nil)
        controller.searchResultsUpdater = self
        controller.dimsBackgroundDuringPresentation = false
        controller.hidesNavigationBarDuringPresentation = false
        controller.searchBar.sizeToFit()

        controller.searchBar.searchBarStyle = UISearchBarStyle.Minimal
        controller.searchBar.barTintColor = UIColor(red: 243/255, green: 243/255, blue: 243/255, alpha: 1)
        controller.searchBar.tintColor = UIColor.blackColor()

        controller.definesPresentationContext = true
        controller.edgesForExtendedLayout = UIRectEdge.None
        self.tableView.contentInset = UIEdgeInsetsMake(64, 0, 0, 0)

        self.tableView.tableHeaderView = controller.searchBar

        return controller
    })()

Really appreciate any help on this!

UPDATE: So I kinda found a not-so-great solution which is to set .active = false in viewWillDisappear. However, the problem is there a searchBar artifact will show on the next/previous VC for a second before completely disappearing.

Answer 1

Change the following:

controller.definesPresentationContext = true

to

self.definesPresentationContext = true

The setting also preserves the state of the search bar when you push and pop a view controller on and off the navigation stack.

You can read about the definesPresentationContext setting on Apple's Documentation on UIViewController.
