字典对象不能转换成JSON对象objective-c

你好我有一个像这样的NSMutableArray。字典对象不能转换成JSON对象objective-c

<__NSArrayM 0x137e9f270>(
{ 
    CanLoadMore = 0; 
    IsFinalLevel = 1; 
    NextLevelApprovers =  (
); 
OrgStructure =  (
      { 
     CreatedBy = 1; 
     CreatedDate = "2015-07-29T12:10:34.297"; 
     Deleted = 0; 
     DeletedBy = 0; 
     DeletedDate = "1901-01-01T00:00:00"; 
     EntityHeadCode = 17098; 
     EntityHeadName = "<null>"; 
     IsPermitted = 0; 
     LegislativeCode = LKA; 
     LevelId = 1; 
     NodeId = 1; 
     OrgEntity = Group; 
     OrgLevelDescription = ""; 
     OrgLevelName = "ABCD Holdings"; 
     OrgStructureId = 1; 
     ParentNodeId = 0; 
     RefOrgLevelId = 1; 
     Status = 1; 
     UpdatedBy = 17113; 
     UpdatedDate = "2016-04-07T08:53:13.727"; 
    }, 
      { 
     CreatedBy = 17113; 
     CreatedDate = "2016-04-06T12:17:19.75"; 
     Deleted = 0; 
     DeletedBy = 0; 
     DeletedDate = "1901-01-01T00:00:00"; 
     EntityHeadCode = 0; 
     EntityHeadName = "<null>"; 
     IsPermitted = 0; 
     LegislativeCode = LKA; 
     LevelId = 2; 
     NodeId = 2; 
     OrgEntity = Company; 
     OrgLevelDescription = ""; 
     OrgLevelName = "ABCD HCM"; 
     OrgStructureId = 2;

    } 
); 
PreviousLevelCount = 0; 
RequestDetails =  { 
    AutoId = 20; 
    LevelId = 1; 
    ModuleId = 2; 
    NoOfLevels = 1; 
    ObjectId = 20; 
    ObjectName = "Leave Request"; 
    RequestForm = "{\"LeaveEntryCode\":0,\"RequestId\":0,\"EmployeeCode\":17227,\"LeaveYear\":2016,\"LeaveTypeCode\":1,\"LeaveReasonCode\":2,\"BaseType\":\"ess\",\"StartDate\":\"2016-08-02T00:00:00\",\"EndDate\":\"2016-08-02T00:00:00\",\"NoOfDays\":1.0,\"StartDateSession\":\"full\",\"EndDateSession\":\"half\",\"PreApproved\":false,\"ForDate\":\"1901-01-01T00:00:00\",\"Remarks\":\"Test 1\",\"CoveringPersonCode\":0,\"AttachedDocument\":null,\"RequestStatus\":\"P\",\"Deleted\":false,\"Status\":false,\"CreatedBy\":0,\"CreatedDate\":\"0001-01-01T00:00:00\",\"UpdatedBy\":0,\"UpdatedDate\":\"0001-01-01T00:00:00\",\"DeletedBy\":0,\"DeletedDate\":\"0001-01-01T00:00:00\",\"ModuleId\":2,\"ObjectId\":20,\"StartDateString\":\"08/02/2016\",\"EndDateString\":\"08/02/2016\",\"LeaveDayList\":[\"08/02/2016-FH,08/02/2016-SH\"],\"SystemLeaveTypeCode\":\"ANN\",\"LeaveTypeName\":\"ANNUAL\",\"Employee\":null,\"LieuDayList\":null,\"BaseLeaveType\":\"ANN\",\"CoveringPersonName\":,\"LeaveReasonName\":\"Leave TypeCasual - Leave - Leave Reason\",\"DocumentSource\":\"LEAVE\"}"; 
    RequestId = 20; 
    RequestedDate = "2016-08-02T05:07:07.127"; 
    WorkflowId = 2; 
}; 
RequesterDetails =  { 
    AdminRequesterName = ""; 
    DisplayName = "<null>"; 
    EmployeeCode = 17227; 
    EmployeeNumber = MM0000019; 
    EtfNo = ""; 
    Gender = Female; 
    ImagePath = "/profile/image/759006c5e4214f0"; 
    Name = haniAAAA; 
}; 
} 
)

我想将其转换为JSON对象。所以我喜欢这个。

NSError *jsonError; 
NSData *objectData = [[[[dm.mutArraySelectedReq objectAtIndex:index] objectForKey:@"RequestDetails"] valueForKey:@"RequestForm"] dataUsingEncoding:NSUTF8StringEncoding]; 
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData 
                  options:NSJSONReadingMutableContainers 
                   error:&jsonError];

但我json字典总是nil。这个RequestForm对象的错误是什么。请帮帮我。感谢

UPDATE

这是我想转换成JSON字符串。

{\"LeaveEntryCode\":0,\"RequestId\":0,\"EmployeeCode\":17227,\"LeaveYear\":2016,\"LeaveTypeCode\":1,\"LeaveReasonCode\":2,\"BaseType\":\"ess\",\"StartDate\":\"2016-08-02T00:00:00\",\"EndDate\":\"2016-08-02T00:00:00\",\"NoOfDays\":1.0,\"StartDateSession\":\"full\",\"EndDateSession\":\"half\",\"PreApproved\":false,\"ForDate\":\"1901-01-01T00:00:00\",\"Remarks\":\"Test 1\",\"CoveringPersonCode\":0,\"AttachedDocument\":null,\"RequestStatus\":\"P\",\"Deleted\":false,\"Status\":false,\"CreatedBy\":0,\"CreatedDate\":\"0001-01-01T00:00:00\",\"UpdatedBy\":0,\"UpdatedDate\":\"0001-01-01T00:00:00\",\"DeletedBy\":0,\"DeletedDate\":\"0001-01-01T00:00:00\",\"ModuleId\":2,\"ObjectId\":20,\"StartDateString\":\"08/02/2016\",\"EndDateString\":\"08/02/2016\",\"LeaveDayList\":[\"08/02/2016-FH,08/02/2016-SH\"],\"SystemLeaveTypeCode\":\"ANN\",\"LeaveTypeName\":\"ANNUAL\",\"Employee\":null,\"LieuDayList\":null,\"BaseLeaveType\":\"ANN\",\"CoveringPersonName\":,\"LeaveReasonName\":\"Leave TypeCasual - Leave - Leave Reason\",\"DocumentSource\":\"LEAVE\"}

更新 - 正确的字符串

{\"LeaveEntryCode\":0,\"RequestId\":0,\"EmployeeCode\":17167,\"LeaveYear\":2016,\"LeaveTypeCode\":2,\"LeaveReasonCode\":0,\"BaseType\":\"ess\",\"StartDate\":\"2016-08-01T00:00:00\",\"EndDate\":\"2016-08-01T00:00:00\",\"NoOfDays\":1.0,\"StartDateSession\":\"full\",\"EndDateSession\":\"full\",\"PreApproved\":false,\"ForDate\":\"1901-01-01T00:00:00\",\"Remarks\":\"\",\"CoveringPersonCode\":0,\"AttachedDocument\":null,\"RequestStatus\":\"P\",\"Deleted\":false,\"Status\":false,\"CreatedBy\":0,\"CreatedDate\":\"0001-01-01T00:00:00\",\"UpdatedBy\":0,\"UpdatedDate\":\"0001-01-01T00:00:00\",\"DeletedBy\":0,\"DeletedDate\":\"0001-01-01T00:00:00\",\"ModuleId\":2,\"ObjectId\":20,\"StartDateString\":\"08/01/2016\",\"EndDateString\":\"08/01/2016\",\"LeaveDayList\":[\"08/01/2016-FH,08/01/2016-SH\"],\"SystemLeaveTypeCode\":\"CAS\",\"LeaveTypeName\":\"CASUAL\",\"Employee\":null,\"LieuDayList\":null,\"BaseLeaveType\":\"ANN\",\"CoveringPersonName\":null,\"LeaveReasonName\":\"Leave TypeCasual - Leave - Leave Reason\",\"DocumentSource\":\"LEAVE\"}

WRONG STRING

{\"LeaveEntryCode\":0,\"RequestId\":0,\"EmployeeCode\":17227,\"LeaveYear\":2016,\"LeaveTypeCode\":1,\"LeaveReasonCode\":2,\"BaseType\":\"ess\",\"StartDate\":\"2016-08-02T00:00:00\",\"EndDate\":\"2016-08-02T00:00:00\",\"NoOfDays\":1.0,\"StartDateSession\":\"full\",\"EndDateSession\":\"half\",\"PreApproved\":false,\"ForDate\":\"1901-01-01T00:00:00\",\"Remarks\":\"Test 1\",\"CoveringPersonCode\":0,\"AttachedDocument\":null,\"RequestStatus\":\"P\",\"Deleted\":false,\"Status\":false,\"CreatedBy\":0,\"CreatedDate\":\"0001-01-01T00:00:00\",\"UpdatedBy\":0,\"UpdatedDate\":\"0001-01-01T00:00:00\",\"DeletedBy\":0,\"DeletedDate\":\"0001-01-01T00:00:00\",\"ModuleId\":2,\"ObjectId\":20,\"StartDateString\":\"08/02/2016\",\"EndDateString\":\"08/02/2016\",\"LeaveDayList\":[\"08/02/2016-FH,08/02/2016-SH\"],\"SystemLeaveTypeCode\":\"ANN\",\"LeaveTypeName\":\"ANNUAL\",\"Employee\":null,\"LieuDayList\":null,\"BaseLeaveType\":\"ANN\",\"CoveringPersonName\":,\"LeaveReasonName\":\"Leave TypeCasual - Leave - Leave Reason\",\"DocumentSource\":\"LEAVE\"}

你应该得到错误，如果JSON字典是零。什么是错误？ – Sujit

因未捕获的异常'NSInvalidArgumentException'而终止应用程序，原因：'*** + [NSJSONSerialization dataWithJSONObject：options：error：]：JSON中的顶级类型无效'这是我得到的错误 – Irrd

我在使用作为漂亮打印的选项 – Irrd

尝试

NSDictionary *json = [NSJSONSerialization JSONObjectWithData:objectData 
                   options:0 
                    error:&jsonError];

不要给任何选项。

然后也无和错误味精是错误域= NSCocoaErrorDomain代码= 3840“字符842周围的无效值。” UserInfo = {NSDebugDescription =字符842周围的值无效} – Irrd

其工作精细

NSString *str = @"{\"LeaveEntryCode\":0,\"RequestId\":0,\"EmployeeCode\":17167,\"LeaveYear\":2016,\"LeaveTypeCode\":2,\"LeaveReasonCode\":0,\"BaseType\":\"ess\",\"StartDate\":\"2016-08-01T00:00:00\",\"EndDate\":\"2016-08-01T00:00:00\",\"NoOfDays\":1.0,\"StartDateSession\":\"full\",\"EndDateSession\":\"full\",\"PreApproved\":false,\"ForDate\":\"1901-01-01T00:00:00\",\"Remarks\":\"\",\"CoveringPersonCode\":0,\"AttachedDocument\":null,\"RequestStatus\":\"P\",\"Deleted\":false,\"Status\":false,\"CreatedBy\":0,\"CreatedDate\":\"0001-01-01T00:00:00\",\"UpdatedBy\":0,\"UpdatedDate\":\"0001-01-01T00:00:00\",\"DeletedBy\":0,\"DeletedDate\":\"0001-01-01T00:00:00\",\"ModuleId\":2,\"ObjectId\":20,\"StartDateString\":\"08/01/2016\",\"EndDateString\":\"08/01/2016\",\"LeaveDayList\":[\"08/01/2016-FH,08/01/2016-SH\"],\"SystemLeaveTypeCode\":\"CAS\",\"LeaveTypeName\":\"CASUAL\",\"Employee\":null,\"LieuDayList\":null,\"BaseLeaveType\":\"ANN\",\"CoveringPersonName\":null,\"LeaveReasonName\":\"Leave TypeCasual - Leave - Leave Reason\",\"DocumentSource\":\"LEAVE\"}" ;
