ios - swift tableview is not reloading after deleting cell -


i have tableview created in storyboard . when try delete cell in tableview(_ tableview: uitableview, editactionsforrowat indexpath: indexpath) -> [uitableviewrowaction] table not reloading after deleting. deleted in database also. when close view , come updated. going wrong? 

func tableview(_ tableview: uitableview, editactionsforrowat indexpath: indexpath) -> [uitableviewrowaction]? {       let deleteaction = uitableviewrowaction(style: .normal, title: "löschen") { (rowaction, indexpath) in               let info: nsdictionary = self.finaltaskvalue[indexpath.item] as! nsdictionary             let pwid = info["pwid"] as! string             self.finaltaskvalue.remove(at: indexpath.row)             self.finaltasktableview.beginupdates()             self.finaltasktableview.deleterows(at: [indexpath], with: .none)             self.finaltasktableview.endupdates()               let url = url(string: "...php")              var request = urlrequest(url: url!)             request.httpmethod = "post"             let body = "parameters"              request.httpbody = body.data(using: .utf8)              urlsession.shared.datatask(with: request) { data, response, error in                  if error == nil {                      dispatchqueue.main.async(execute: {                          do{                             let json = try jsonserialization.jsonobject(with: data!, options: []) as? nsdictionary                               guard let parsejson = json else {                                 print("")                                 return                             }                             dispatchqueue.main.async(execute: {                             self.finaltasktableview.reloaddata()                             })                          }catch {                             //print("caught error: \(error)")                             dispatchqueue.main.async(execute: {                                 let message = "server ist offline! wir arbeiten mit hochdruck dran alles zu reparieren"                          }                     })                  }else {                      dispatchqueue.main.async(execute: {                         let message = error!.localizeddescription                   }                  }.resume()         }       deleteaction.backgroundcolor = colordarkgreen     return [deleteaction] }

1) have check tableview data final task value. 2) please when perform delete action don't use begin update , begin end update method please user reload method shown here.

finaltasktableview.reloaddata()

3) don't understand why define url request here? 4) request not using parameter of method or delete logic parameter not included. check request response fill again data want delete.

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
