#import <CkoJsonObject.h>
#import <NSString.h>

// Create JSON with members of different data types.
CkoJsonObject *json = [[CkoJsonObject alloc] init];

[json UpdateInt: @"a" value: [NSNumber numberWithInt: 123]];
[json UpdateBool: @"b" value: YES];
[json UpdateNull: @"c"];

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

// Resulting JSON:
// {
//   "a": 123,
//   "b": true,
//   "c": null
// }

NSString *a = [json StringOf: @"a"];
NSLog(@"%@",a);

NSString *b = [json StringOf: @"b"];
NSLog(@"%@",b);

NSString *c = [json StringOf: @"c"];
NSLog(@"%@",c);

// Output

// 123
// true
// null

// If you want to get the integer, boolean, or null value
// you need to use the methods matching the data type
int ival = [[json IntOf: @"a"] intValue];
BOOL bval = [json BoolOf: @"b"];
BOOL hasNull = [json IsNullOf: @"c"];
