Incorrect conversion from object to JSON? - ios

Question

I need to send to a web service this JSON by POST:
{
"plantilla" : "IL3\/il3_prof",
"contacto" : {
"email" : "vgonzalez#ub.edu",
"nombre" : "Vanesa",
"movilPersonal" : "934037680",
"apellidos" : "Gonzalez Jimenez."
"direccionTrabajoDTO" : {
"direccion" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
},
},
"valoresPlantilla" : [
{
"key" : "nombre",
"value" : "Vanesa Gonzalez Jimenez."
},
{
"key" : "curso",
"value" : "Curs de test per Tecnologia"
},
{
"key" : "linked",
"value" : "es.linkedin.com\/in\/"
},
{
"key" : "direccion",
"value" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
},
{
"key" : "email",
"value" : "vgonzalez#ub.edu"
},
{
"key" : "telefono",
"value" : "934037680"
}
]
}
I created the object Tarjeta with values:
Tarjeta *tarjeta = [[Tarjeta alloc] init];
tarjeta.plantilla = #"IL3/il3_prof";
Contacto *contacto = [[Contacto alloc] init];
contacto.nombre = #"Vanesa";
contacto.apellidos = #"Gonzalez Jimenez.";
contacto.email = #"vgonzalez#ub.edu";
contacto.movilPersonal = #"934037680";
DireccionTrabajo *direccionTrabajo = [[DireccionTrabajo alloc] init];
direccionTrabajo.direccion = #"Feixa Llarga, S/N 08970 Hospitalet De Llobregat (Barcelona), España";
contacto.direccionTrabajo = direccionTrabajo;
tarjeta.contacto = contacto;
ValorPlantilla *nombre = [[ValorPlantilla alloc] init];
nombre.key = #"nombre";
nombre.value = #"Vanesa Gonzalez Jimenez.";
ValorPlantilla *curso = [[ValorPlantilla alloc] init];
curso.key = #"curso";
curso.value = #"Curs de test per Tecnologia";
ValorPlantilla *linked = [[ValorPlantilla alloc] init];
linked.key = #"linked";
linked.value = #"es.linkedin.com/in/";
ValorPlantilla *direccion = [[ValorPlantilla alloc] init];
direccion.key = #"direccion";
direccion.value = #"Feixa Llarga, S/N 08970 Hospitalet De Llobregat (Barcelona), España";
ValorPlantilla *email = [[ValorPlantilla alloc] init];
email.key = #"email";
email.value = #"vgonzalez#ub.edu";
ValorPlantilla *telefono = [[ValorPlantilla alloc] init];
telefono.key = #"telefono";
telefono.value = #"934037680";
tarjeta.valoresPlantilla = [NSArray arrayWithObjects:nombre, curso, linked, direccion, email, telefono, nil];
return tarjeta;
After this, I do a conversion from object to JSON with this method:
NSMutableDictionary *tarjetaDict = [[NSMutableDictionary alloc] init];
[tarjetaDict setValue:tarjeta.plantilla forKey:#"plantilla"];
NSMutableDictionary *contactoDict = [[NSMutableDictionary alloc] init];
[contactoDict setValue:tarjeta.contacto.nombre forKey:#"nombre"];
[contactoDict setValue:tarjeta.contacto.apellidos forKey:#"apellidos"];
[contactoDict setValue:tarjeta.contacto.email forKey:#"email"];
[contactoDict setValue:tarjeta.contacto.movilPersonal forKey:#"movilPersonal"];
NSMutableDictionary *direccionDict = [[NSMutableDictionary alloc] init];
[direccionDict setValue:tarjeta.contacto.direccionTrabajo.direccion forKey:#"direccion"];
[contactoDict setValue:direccionDict forKey:#"direccionTrabajoDTO"];
[tarjetaDict setValue:contactoDict forKey:#"contacto"];
[tarjetaDict setValue:tarjeta.valoresPlantilla forKey:#"valoresPlantilla"];
return tarjetaDict;
When I finish this process, I send the NSMutableDictionary like JSON to the web service, but it says that's incorrect and this is the error.
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Invalid type in JSON write (ValorPlantilla)'
I'm doing anything wrong?

Answer 1

Add this method to your ValorPlantilla class
-(NSMutableDictionary *)getobject
{
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
[dict setObject:self.key forKey:#“key"];
[dict setObject:self.value forKey:#“value"];
return dict;
}
And Change this line
tarjeta.valoresPlantilla = [NSArray arrayWithObjects:[nombre getobject], [curso, linked getobject], [direccion getobject], [email getobject], [telefono getobject], nil];
This might works

Answer 2

First make below six individual dictionary,
{
"key" : "nombre",
"value" : "Vanesa Gonzalez Jimenez."
},
{
"key" : "curso",
"value" : "Curs de test per Tecnologia"
},
{
"key" : "linked",
"value" : "es.linkedin.com\/in\/"
},
{
"key" : "direccion",
"value" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
},
{
"key" : "email",
"value" : "vgonzalez#ub.edu"
},
{
"key" : "telefono",
"value" : "934037680"
}
Then create one array let's say temp array, add this all six dictionary to that array.
Then make below dictionary let's say tempDic,
"contacto" : {
"email" : "vgonzalez#ub.edu",
"nombre" : "Vanesa",
"movilPersonal" : "934037680",
"apellidos" : "Gonzalez Jimenez."
"direccionTrabajoDTO" : {
"direccion" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
},
},
It's having sub dictioanry.
Then make standard dictionary(final) and set three objects : plantilla, tempDic and temp array
So, your object is ready to send.
Now, don't convert it in json. Convert it in NSdata like below
If your final dictionary's name is finalDic then,
NSData *data = [NSJSONSerialization dataWithJSONObject:finalDic options:0 error:nil];
And send that data to server.
If you are using AFNetworking then you not need to convert finalDic to data. Afnetworking manage automatically, just pass that finalDict as parameter of webservice call by AFNetworking.
Hope this will help :)

Please check your json data wrong below url:

{
"plantilla" : "IL3\/il3_prof",
"contacto" : {
"email" : "vgonzalez#ub.edu",
"nombre" : "Vanesa",
"movilPersonal" : "934037680",
"apellidos" : "Gonzalez Jimenez.", //Please separate ','
"direccionTrabajoDTO" : {
"direccion" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
} // Please remove separete
},
"valoresPlantilla" : [
{
"key" : "nombre",
"value" : "Vanesa Gonzalez Jimenez."
},
{
"key" : "curso",
"value" : "Curs de test per Tecnologia"
},
{
"key" : "linked",
"value" : "es.linkedin.com\/in\/"
},
{
"key" : "direccion",
"value" : "Feixa Llarga, S\/N 08970 Hospitalet De Llobregat (Barcelona), España"
},
{
"key" : "email",
"value" : "vgonzalez#ub.edu"
},
{
"key" : "telefono",
"value" : "934037680"
}
]
}
