Question

I am trying to use RestKit on my app, and currently using master on github as a git submodule. The whole thing is installed and running. However, when I try to get JSON data from my rails app, I am getting a BAD_EXC_ACCESS on RestKit, more specifically on RKObjectLoader.m, line 365.

if ([_delegate respondsToSelector:@selector(request:didLoadResponse:)]) {
    [_delegate request:self didLoadResponse:_response];
}

Not sure what is going on here but should I assume it is a problem with Restkit?

Here is what I am trying to do:

-(id) init {
    self = [super init];
    if (self) {
        RKObjectMapping* patientMapping = [RKObjectMapping mappingForClass:[Patient class]];

        [patientMapping mapKeyPath:@"id" toAttribute:@"identifier"];
        [patientMapping mapKeyPath:@"first_name" toAttribute:@"first_name"];
        [patientMapping mapKeyPath:@"middle_initial" toAttribute:@"middle_initial"];
        [patientMapping mapKeyPath:@"last_name" toAttribute:@"last_name"];
        [patientMapping mapKeyPath:@"email" toAttribute:@"email"];
        [patientMapping mapKeyPath:@"password_hint_question" toAttribute:@"password_hint_question"];
        [patientMapping mapKeyPath:@"password_hint_answer" toAttribute:@"password_hint_answer"];

        [[RKObjectManager sharedManager].mappingProvider setMapping:patientMapping forKeyPath:@"patients"];
    }
    return self;
}

- (void)loadAll {
    [[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"/ios_patient.json" delegate:self];
}

So basically I instantiate this class and call loadAll. My ios_patient.json is returning the following JSON code:

{"patients": [{"id": 1, "first_name": "John", "last_name": "Appleseed", "email": "[e-mail]"}]}

Any help would be much appreciated.

Thanks for the comments. It turns out RestKit is not compatible with ARC and yes, I was using it. The variables were properly mapped (even though they were not camelcase) and the delegates were being properly set and implemented as well. Good thing I am early in the development process and can get back to non ARC.
