See more JSON Examples

Demonstrates how to load a JsonArray.

Note: This example requires Chilkat v9.5.0.64 or greater.

Objective-C

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

// This example requires Chilkat v9.5.0.64 or greater.

// Loading into a new JSON array is simple and straightforward.
CkoJsonArray *a = [[CkoJsonArray alloc] init];
[a Load: @"[ 1,2,3,4 ]"];

// Output:  [1,2,3,4]
NSLog(@"%@",[a Emit]);
NSLog(@"%@",@"--------");

// The JsonArray's Load and LoadSb methods have a peculiar behavior when
// it is already part of a JSON document.  In this case, the JsonArray
// becomes detached, and the original document remains unchanged.
// This is intentional due to the nature of the internal implementation.
// For example:

CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json Load: @"{ \"abc\": [ 1,2,3,4 ] }"];

// Output:  (json) {"abc":[1,2,3,4]}
NSLog(@"%@%@",@"(json) ",[json Emit]);
NSLog(@"%@",@"--------");

CkoJsonArray *abc = [json ArrayOf: @"abc"];
// When Load is called, abc becomes it's own document, and the original is not modified.
[abc Load: @"[ 5,6,7,8 ]"];

// Output: (abc) [5,6,7,8]
NSLog(@"%@%@",@"(abc) ",[abc Emit]);
NSLog(@"%@",@"--------");

// Output: (json) {"abc":[1,2,3,4]}
NSLog(@"%@%@",@"(json) ",[json Emit]);
NSLog(@"%@",@"--------");
