See more JSON Examples

Demonstrates how to sort the members of a JSON object by the key name. Objective-C

#import <CkoJsonObject.h>

CkoJsonObject *json = [[CkoJsonObject alloc] init];

[json UpdateString: @"xyz" value: @"1234"];
[json UpdateString: @"abc.xyz" value: @"1234"];
[json UpdateString: @"abc.def" value: @"1234"];
[json UpdateString: @"abc.aaa" value: @"1234"];
[json UpdateString: @"ghi" value: @"1234"];
[json UpdateString: @"nmo" value: @"1234"];

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

// This is our initial JSON:

// {
//   "xyz": "1234",
//   "abc": {
//     "xyz": "1234",
//     "def": "1234",
//     "aaa": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234"
// }

// Sort the top-level JSON object by key.
BOOL ascending = YES;
BOOL caseSensitive = YES;
[json Sort: ascending caseSensitive: caseSensitive];

// Look at the sorted JSON..
NSLog(@"%@",[json Emit]);

// {
//   "abc": {
//     "xyz": "1234",
//     "def": "1234",
//     "aaa": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234",
//   "xyz": "1234"
// }

// Now sort the members of the "abc" object..
CkoJsonObject *jsonAbc = [[CkoJsonObject alloc] init];
[json ObjectOf2: @"abc" jsonObj: jsonAbc];

[jsonAbc Sort: ascending caseSensitive: caseSensitive];

// Now look at the JSON with the members under "abc" also sorted..
NSLog(@"%@",[json Emit]);

// {
//   "abc": {
//     "aaa": "1234",
//     "def": "1234",
//     "xyz": "1234"
//   },
//   "ghi": "1234",
//   "nmo": "1234",
//   "xyz": "1234"
