JSONkit sorting issues

I have the following jSON

[
  {
    "Pending": 67,
    "Past Due": 63,
    "Invites": 0
  },
  {
    "Reading Approval": 4,
    "Schedule Approval": 16,
    "Session Assignment": 1
  },
  {
    "Reading Approval": 3,
    "Schedule Approval": 20,
    "Class Approval": 20,
    "Module Approval": 2,
    "Training Plan Review": 2,
    "Job Confirmation": 1
  }

]

When I assign the json string to a nsarray the values inside the dictionary gets sorted alphabetically.

NSArray *arr = [strResult JSONValue]; 

How can I keep the same order as the json string?

arr = 
{
  Invites = 0;
  "Past Due" = 63;
  Pending = 67;
},
{
  "Reading Approval" = 4;
  "Schedule Approval" = 16;
  "Session Assignment" = 1;
},
{
  "Class Approval" = 20;
  "Job Confirmation" = 1;
  "Module Approval" = 2;
  "Reading Approval" = 3;
  "Schedule Approval" = 20;
  "Training Plan Review" = 2;
}
)

This is the table I want to display:

Group 1
  Pending    67
  Past Due   63
  Invites    0

Group 2
  Reading Approval    4
  Schedule Approval   16
  Session Assignment  1

Group 3
  Reading Approval      3
  Schedule Approval     20
  Class Approval        20
  Module Approval       2
  Training Plan Review  2
  Job Confirmation      1

Answer 1

Using standard JSON parsers, you will need to change your data.

[
  [
    { "Pending": 67 },
    { "Past Due": 63 },
    { "Invites": 0 }
  ],
  [
    { "Reading Approval": 4 },
    { "Schedule Approval": 16 },
    { "Session Assignment": 1 }
  ],
  [
    { "Reading Approval": 3 },
    { "Schedule Approval": 20 },
    { "Class Approval": 20 },
    { "Module Approval": 2 },
    { "Training Plan Review": 2 },
    { "Job Confirmation": 1 }
  ]
]

Assuming it’s possible for you to change your JSON format.

How to access the data. Assuming you have the array of sections and know the section and row indexes.

NSArray *sections = ...
NSUInteger sectionIndex = ...
NSUInteger rowIndex = ...

NSArray *rows = [sections objectAtIndex:sectionIndex];
NSDictionary *cell = [rows objectAtIndex:rowIndex];

NSString *name = [[cell allKeys] objectAtIndex:0];
NSNumber *value = [cell objectForKey:name];

// What ever you need to do

If you want to iterate over all the data

NSArray *sections = ...

for (NSArray *rows in sections) {
    for (NSDictionary *cell in rows) {
        NSString *name = [[cell allKeys] objectAtIndex:0];
        NSNumber *value = [cell objectForKey:name];

        // What ever you need to do
    }
}
