如何在Objective-C中增加Json对象

Question

how to increment an Array of Json?

I have this array, this "jsonObjects" loads a Json from webservice:

            arrBusca = [jsonObjects objectForKey:key];

If I print this array, results this:

2013-03-26 16:50:48.167 teste[6645:907] array 1: (
    {
    idMarca = 118;
    idTipo = 1;
    marca = "";
    ordem = 9999;
    tipo = Carro;
    },
    {
    idMarca = 60;
    idTipo = 1;
    marca = " -";
    ordem = 2;
    tipo = Carro;
    },
    {
    idMarca = 117;
    idTipo = 1;
    marca = "---";
    ordem = 2;
    tipo = Carro;
   }
}

And I want to increment this array, so I try:

    marcas *myPerson = [[marcas alloc] init];
    myPerson.marca = [NSString stringWithFormat:@"Fiat %d", i];
    myPerson.idMarca = [NSString stringWithFormat:@"%d", i];
    [arrBusca addObject:myPerson];

But the result is:

2013-03-26 16:50:48.167 teste[6645:907] array 1: (
    {
    idMarca = 118;
    idTipo = 1;
    marca = "";
    ordem = 9999;
    tipo = Carro;
    },
    {
    idMarca = 60;
    idTipo = 1;
    marca = " -";
    ordem = 2;
    tipo = Carro;
    },
    {
    idMarca = 117;
    idTipo = 1;
    marca = "---";
    ordem = 2;
    tipo = Carro;
   },
"<marcas: 0x1fd807e0>",
"<marcas: 0x1fd89e40>",
"<marcas: 0x1fd80c90>",
"<marcas: 0x1fd8a1b0>",
"<marcas: 0x1fd8ada0>",
"<marcas: 0x1fd89cb0>",
}

Anyone knows how to increment an jsonobject array?

Answer 1

You need to provide NSCoder methods to archive and unarchive your " marcas " objects.

Right now, when you add the objects to your " arrBusca " NSMutableArray (it is mutable, right?), they're being added as " marcas " objects and not the raw non-marcas objects you decoded from JSON).
