CkoJsonArray *arr = [[CkoJsonArray alloc] init];

BOOL success;

// Add an empty object at the 1st JSON array position.
[arr AddObjectAt: [NSNumber numberWithInt: 0]];
// Get the object we just created.
CkoJsonObject *obj = [arr ObjectAt: [NSNumber numberWithInt: 0]];
[obj UpdateString: @"Name" value: @"Otto"];
[obj UpdateInt: @"Age" value: [NSNumber numberWithInt: 29]];
[obj UpdateBool: @"Married" value: NO];

// Add an empty object at the 2nd JSON array position.
[arr AddObjectAt: [NSNumber numberWithInt: 1]];
obj = [arr ObjectAt: [NSNumber numberWithInt: 1]];
[obj UpdateString: @"Name" value: @"Connor"];
[obj UpdateInt: @"Age" value: [NSNumber numberWithInt: 43]];
[obj UpdateBool: @"Married" value: YES];

// Add an empty object at the 3rd JSON array position.
[arr AddObjectAt: [NSNumber numberWithInt: 2]];
obj = [arr ObjectAt: [NSNumber numberWithInt: 2]];
[obj UpdateString: @"Name" value: @"Ramona"];
[obj UpdateInt: @"Age" value: [NSNumber numberWithInt: 34]];
[obj UpdateBool: @"Married" value: YES];

// Examine what we have:
arr.EmitCompact = NO;
NSLog(@"%@",[arr Emit]);

// The output is:

// [
//   {
//     "Name": "Otto",
//     "Age": 29,
//     "Married": false
//   },
//   {
//     "Name": "Connor",
//     "Age": 43,
//     "Married": true
//   },
//   {
//     "Name": "Ramona",
//     "Age": 34,
//     "Married": true
//   }
