[string: anyobject] {                // let date = nsdate()                 snapshot in snapshots {                     if let dict = snapshot.value as? [string: anyobject] {             let name = (dict["name"] as? string) ?? ""             let photostring = (dict["photo"] as? string) ?? ""             let aphoto = base64.convertbase64toimage(photostring)             self.object1.append(item(photo: photostring, name: name))             //self.object1.removeall()                     }                 }             }         self.tableview.reloaddata()     })  }
