   "apple": "red",
   "lime": "green",
   "banana": "yellow",
   "broccoli": "green",
   "strawberry": "red"
}

Objective-C

#import <CkoJsonObject.h>

BOOL success = NO;

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

success = [json Load: @"{\"apple\": \"red\",\"lime\": \"green\",\"banana\": \"yellow\",\"broccoli\": \"green\",\"strawberry\": \"red\"}"];
if (success != YES) {
    NSLog(@"%@",json.LastErrorText);
    return;
}

// Rename "lime" to "lemon".
success = [json Rename: @"lime" newName: @"lemon"];
// Change the color to yellow:
success = [json SetStringOf: @"lemon" value: @"yellow"];

// Rename by index.  Banana is at index 2 (apple is at index 0)
success = [json RenameAt: [NSNumber numberWithInt: 2] name: @"bartlett_pear"];

// Delete broccoli by name
success = [json Delete: @"broccoli"];

// Delete apple by index.  Apple is at index 0.
success = [json DeleteAt: [NSNumber numberWithInt: 0]];

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