creating JSON format in Objective C

Question

For an application i want to create a JSON in format as mentioned below,

\"Students\" : {
    \"results\": {
        \"Grade1\": {
            \"studentresul         


        

Answer 1

In order to get the format you want out of it, you have to pack information in that particular format.

Your problem is right about here:

NSMutableArray *rarray = [[NSMutableArray alloc] init];
[rarray addObject:grade];
[rarray addObject:sdetails];

The desired format has no arrays, so why are you creating an array?

A hint for you:

You should be creating exactly 4 dictionaries, and no arrays.
