How to pass a NSArray to a POST using MKNetworkKit

Question

MKNetworkOperation *op = [self operationWithPath:@"thestore/services/storeservice.svc/getfavorites" params:fetchedObjects httpMethod:@"POST"];

The fetechedObjects is an array. I can loop through the array to get the values I need to put into the POST request body

[
 {
     "id": 9222,
    "latitude": 19.7897,
    "longitude": -64.0208
 },
 {
     "id": 7832,
     "latitude": 79.7713,
     "longitude": -44.1084
 }
]

But I can't figure out how to use the MKNetworkOperation

Answer 1

The first thing to try is to set the postDataEncoding property of the operation to MKNKPostDataEncodingTypeJSON. This should cause the array to be serialized and set as the request body.

However, MKNetworkKit doesn't really support array values for the params parameter; it expects a dictionary. If you hit the wrong code path, it could crash because it expects a dictionary where you've provided an array.
