Demonstrates how to insert a JSON array into a JSON object. Objective-C

#import <CkoJsonObject.h>
#import <CkoJsonArray.h>

// Imagine we have two separate JSON objects.
CkoJsonObject *jsonA = [[CkoJsonObject alloc] init];
[jsonA UpdateString: @"ciphertext" value: @"encryptedData"];
[jsonA UpdateInt: @"status" value: [NSNumber numberWithInt: 200]];
[jsonA UpdateString: @"error" value: @"errorMsg"];

jsonA.EmitCompact = NO;
NSLog(@"%@",[jsonA Emit]);

// jsonA contains:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg"
// }

CkoJsonObject *jsonB = [[CkoJsonObject alloc] init];
[jsonB UpdateString: @"users[0].role" value: @"Surgeon"];
[jsonB UpdateNewArray: @"users[0].sub_roles"];
[jsonB UpdateBool: @"users[0].viewable_for_sharing" value: YES];
[jsonB UpdateInt: @"users[0].eula_create_date" value: [NSNumber numberWithInt: 123]];
[jsonB UpdateString: @"users[1].role" value: @"Support"];
[jsonB UpdateString: @"users[1].sub_roles[0]" value: @"Tech"];
[jsonB UpdateString: @"users[1].sub_roles[1]" value: @"Service"];
[jsonB UpdateBool: @"users[1].viewable_for_sharing" value: YES];
[jsonB UpdateInt: @"users[1].eula_create_date" value: [NSNumber numberWithInt: 123]];

jsonB.EmitCompact = NO;
NSLog(@"%@",[jsonB Emit]);

// jsonB contains:

// {
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108922482
//     },
//     {
//       "role": "Support",
//       "sub_roles": [
//         "Tech",
//         "Service"
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108951523
//     }
//   ]
// }

// Let's say we want to insert jsonB into jsonA to get this:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg",
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108922482
//     },
//     {
//       "role": "Support",
//       "sub_roles": [
//         "Tech",
//         "Service"
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 1649108951523
//     }
//   ]
// }

// The destination is the empty "users" array, the source is the populated "users" array in jsonB.
CkoJsonArray *jsonUsersDest = [[CkoJsonArray alloc] init];
[jsonA AppendArray2: @"users" jarr: jsonUsersDest];

CkoJsonArray *jsonUsersSrc = [[CkoJsonArray alloc] init];
[jsonB ArrayOf2: @"users" jarr: jsonUsersSrc];

// Copy the array items from source to dest
[jsonUsersDest AppendArrayItems: jsonUsersSrc];

NSLog(@"%@",[jsonA Emit]);

// The end result is this:

// {
//   "ciphertext": "encryptedData",
//   "status": 200,
//   "error": "errorMsg",
//   "users": [
//     {
//       "role": "Surgeon",
//       "sub_roles": [
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 123
//     },
//     {
//       "role": "Support",
//       "sub_roles": [
//         "Tech",
//         "Service"
//       ],
//       "viewable_for_sharing": true,
//       "eula_create_date": 123
//     }
//   ]
// }
