无法在解析Sdk上从iOS更新对象

Question

我尝试从Parse CloudCode函数中更新Parse对象。我想更新一个特定条目的status_id，它的objectId是“vZveFx3KcP”。每当我调用以下函数时，没有更新任何条目。但是每当我从Android设备中添加手动条目或条目时，它就会被更新。对于iOS，我使用的是最新的分析版本"1.11.0“。只对由iOS平台添加的条目进行了更新。。

有谁能解释一下我哪里出错了吗？我是javascript编程新手，所以如果您需要我提供更多的信息，请告诉我。你可以在下面检查我的代码。我尝试过从Parse控制台调用云函数。

   Parse.Cloud.define("freshFunction", function(request, response) {

               var GameScore = Parse.Object.extend("Booking");
               var query = new Parse.Query(GameScore);
               query.equalTo("objectId", "vZveFx3KcP");
               query.first({
                          success: function(results) {

                          alert("Successfully retrieved " + results.length + "user_id");

                          results.set("status_id", 2);
                          results.save();
                          response.success();
                          },
                          error: function(error) {
                          alert("Error: " + error.code + " " + error.message);
                           response.error();
                          }
                          });

               });

通过创建云函数并从iOS平台调用它，解决了这个问题。在云中添加了以下代码。

Parse.Cloud.define("callCloudFunctionFromDevice", function(request, response) {

                   var bookfromtime = request.params.book_fromtime;
                   var booktotime = request.params.book_totime;
                   var bookdate = request.params.book_date;
                   var roommacid = request.params.room_mac_id;
                   var userid= request.params.user_id;
                   var ttl= request.params.title;
                   var desc= request.params.description;
                   var statusid= request.params.status_id;


                   var SensorsObject = Parse.Object.extend("Booking");
                   var senorObject = new SensorsObject();

                   senorObject.set("book_fromtime", bookfromtime);
                   senorObject.set("book_totime", booktotime);
                   senorObject.set("book_date", bookdate);
                   senorObject.set("room_mac_id", roommacid);
                   senorObject.set("user_id", userid);
                   senorObject.set("title", ttl);
                   senorObject.set("description", desc);
                   senorObject.set("status_id", statusid);




                   senorObject.save(null, {
                                    success: function(gameScore) {
                                    // response.success("Sensor Data is stored");
                                    response.success("success");
                                    },
                                    error: function(gameScore, error) {
                                    // Execute any logic that should take place if the save fails.
                                    // error is a Parse.Error with an error code and message.
                                    alert('Failed to create new object, with error code: ' + error.message);
                                    response.error("Failed to store object data");
                                    }
                                    });
                   });

一旦在云中部署了上面的代码，我就从iOS平台调用‘iOS’函数。请参阅以下代码

[PFCloud callFunctionInBackground:@"callCloudFunctionFromDevice" //This is the Parse function
                       withParameters:mDictionary
                                block:^(NSString *CalUsed1, NSError *error) { // This is where the block starts
                                    if (!error) { //if the block retrieves the data with no problem, this will run
                                        NSLog(@"Calories");
                                        [self hideBusyActivityView];
                                        [self.navigationController popViewControllerAnimated:YES];
                                    }
                                    else
                                    {
                                        NSLog(@"TDEE IN FN is");
                                        [self hideBusyActivityView];
                                        [self showAlertWithMessage:error.localizedDescription];
                                    }
                                }];

其中mDictionary是有效载荷。
