ios - Deleting a row from a tableView with multiple rows in section -

when try , delete row section multiple rows, when slide left reveal delete button , press it, deletes once tableview refreshed, visually nothing. if press again, deletes both rows in section. if dont press again , press , come viewcontroller, delete has worked animation never happened. deleting cell in section there 1 cell works perfectly. when there 2 cells or more in section, delegate functions never called commiteditingstyle does. let me know if need more code. thanks.

here nsfetchedresultscontrollerdelegate methods

override func tableview(tableview: uitableview, commiteditingstyle editingstyle: uitableviewcelleditingstyle, forrowatindexpath indexpath: nsindexpath) {           let object = self.fetchedresultscontroller.objectatindexpath(indexpath) nsmanagedobject         self.context.deleteobject(object)         try! context.save() }  func controllerwillchangecontent(controller: nsfetchedresultscontroller) {  }  func controllerdidchangecontent(controller: nsfetchedresultscontroller, didchangeobject anobject: anyobject, atindexpath indexpath: nsindexpath?, forchangetype type: nsfetchedresultschangetype, newindexpath: nsindexpath?) {     var tableview = self.tableview uitableview     switch(type)     {     case .delete:         if let indexpath = indexpath         {             print("delete")             tableview.deleterowsatindexpaths(nsarray(object:indexpath) as! [nsindexpath], withrowanimation: uitableviewrowanimation.fade)         }         break     case .update:         if let indexpath = indexpath         {             if let cell = tableview.cellforrowatindexpath(indexpath)             {             cell.textlabel!.text = (self.fetchedresultscontroller.valueforkey("firstname") as! string) + " " + (self.fetchedresultscontroller.valueforkey("lastname") as! string)                 print("update")             }         }     default:         break     }   }  func controller(controller: nsfetchedresultscontroller,     didchangesection sectioninfo: nsfetchedresultssectioninfo,     atindex sectionindex: int,     forchangetype type: nsfetchedresultschangetype) {     switch(type)     {     case .delete:         tableview.deletesections(nsindexset(index:sectionindex), withrowanimation: uitableviewrowanimation.fade)     break     default:     break     } } func controllerdidchangecontent(controller: nsfetchedresultscontroller) {  } 

solution: needed add self.tableview.reloaddata() @ end of commiteditingstyle function

override func tableview(tableview: uitableview, commiteditingstyle editingstyle: uitableviewcelleditingstyle, forrowatindexpath indexpath: nsindexpath) {           let object = self.fetchedresultscontroller.objectatindexpath(indexpath) nsmanagedobject         self.context.deleteobject(object)         try! context.save() self.tableview.reloaddata() } 

add self.tableview.reloaddata() after delete row, or row technically deleted, table view has not been updated yet. see updated code below...

        func controller(controller: nsfetchedresultscontroller,             didchangesection sectioninfo: nsfetchedresultssectioninfo,             atindex sectionindex: int,             forchangetype type: nsfetchedresultschangetype)         {             switch(type)             {             case .delete:  //this creates delete annimation                 tableview.deletesections(nsindexset(index:sectionindex), withrowanimation: uitableviewrowanimation.fade)   //this deletes row array     self.array.removeatindex(indexpath.row)          //this reloads table view can see row deleted.         self.tableview.reloaddata()                break             default:             break             }         }
