ios - How to stop UIActivityIndicator after UISearchBar has finished in Swift -


so set up:

i'm have app set parse, , i'm using pfquerytableviewcontroller. i've added uisearchbar screen. have search set , working fine.

question: make bit more obvious user search being performed, want add uiactivityindicator can see loading. beginignoringinteractionevents() cannot use app until search complete.

i'm having issues how make uiactivityindicator stop animating, , endignoringinteractionevents()- can't work out place code:

spinningactivityindicator.stopanimating() uiapplication.sharedapplication().endignoringinteractionevents()

i have placed code uiactivityindicator inside method func searchbarsearchbuttonclicked(searchbar: uisearchbar) once click search on keyboard, spinner start.

but can place code stop animating , enable app again?

the code added uisearchbar follows:

func searchbartextdidbeginediting(searchbar: uisearchbar) {      searchbar.showscancelbutton = true      self.loadobjects()  }  func searchbartextdidendediting(searchbar: uisearchbar) {      // dismiss keyboard     searchbar.resignfirstresponder()      // force reload of table data     self.loadobjects() }  func searchbarsearchbuttonclicked(searchbar: uisearchbar) {      // dismiss keyboard     searchbar.resignfirstresponder()      spinningactivityindicator = uiactivityindicatorview(frame: cgrectmake(0, 0, 50, 50))     spinningactivityindicator.center = self.view.center     spinningactivityindicator.hideswhenstopped = true     spinningactivityindicator.activityindicatorviewstyle = uiactivityindicatorviewstyle.gray     view.addsubview(spinningactivityindicator)     spinningactivityindicator.startanimating()     uiapplication.sharedapplication().beginignoringinteractionevents()       searchbar.showscancelbutton = false      // force reload of table data     self.loadobjects()  }  func searchbarcancelbuttonclicked(searchbar: uisearchbar) {      // clear search criteria     searchbar.text = ""      // dismiss keyboard     searchbar.resignfirstresponder()      // force reload of table data     self.loadobjects() }

and in func queryfortable() -> pfquery added:

    if filmsearchbar.text != "" {         query.wherekey("filmname", containsstring: filmsearchbar.text!)      }

thanks in advance!

i checked through of documentation pfquerytableviewcontroller, , there's method objectsdidload() seems promising. so, try adding below queryfortable() function:

override func objectsdidload(error: nserror?) {     super.objectsdidload(error)     // code here stop uiactivityindicator }

and add print("objectsdidload") inside function see works.
