UPDATE:

I found that the reason for the previous error was an error in the documentation.

The method should be named proxyForJson, not jsonProxyObject...

But I'm still stuck, though.

I now get an EXC_BAD_ACCESS error inside stringWithObject some where. Any clues?


UPDATE 2:

My proxyForJson implementation is a cut-n-paste from then documentation:

- (id)proxyForJson {
    return [NSDictionary dictionaryWithObjectsAndKeys:
            Navn, @"Navn",
            Adresse, @"Adresse",
            Alder, @"Alder",
            nil];
}

Trying to make json serialization work for my custom objective-c class.

As I understand the documentation, json-framework can serialize custom objects, if they implement the jsonProxyObject method.

So I have this class:

@interface MyObject : NSObject {
    NSString *Name;
    NSString *Addresse;
    NSInteger Age;
}
@property (nonatomic, retain) NSString *Name;
@property (nonatomic, retain) NSString *Addresse;
@property (nonatomic, assign) NSInteger Age;
- (id)jsonProxyObject;
@end

And I try to serialize an array with some instances in it:

[json stringWithObject:list error:&error];

But all I get is he following error:

"JSON serialisation not supported for MyObject"

I guess the jsonWriter can't find my jsonProxyObject method for some reason, buy why?
