"collection element of type BOOL" is not an objective-c object

Question

Anyone have a clue why I am getting this?

-(void)postPrimaryEMWithEM:(EM *)em
              exclusive:(BOOL) isExclusive
                 success:(void (^)())onSuccess
                 failure:(void (^)())onFailure {


if(self.accessToken) {


    GenericObject *genObject = [[GenericObject alloc] init];

    [[RKObjectManager sharedManager] postObject:genObject
                                          path:@"users/update.json"
                                    parameters:@{
                                                  ...
                                                 @"em_id"  : ObjectOrNull(em.emID),
                                                 @"exclusive": isExclusive  <-- error message

Answer 1

Remove the pointer ('*') form your BOOL:

exclusive:(BOOL*) isExclusive

and change:

@"exclusive": isExclusive

to:

@"exclusive": [NSNumber numberWithBool:isExclusive]

or:

// Literal version of above NSNumber
@"exclusive": @(isExclusive)

As a note, NSDictionary cannot store primitive types, including booleans. So you have to encapsulate the value in an object, in this case NSNumber.

Answer 2

You cannot put a fundamental data type in a dictionary. It must be an object. But you can use [NSNumber numberWithBool:isExclusive] or use the @(isExclusive) syntax:

[[RKObjectManager sharedManager] postObject:genObject
                                       path:@"users/update.json"
                                 parameters:@{
                                              ...
                                             @"em_id"  : ObjectOrNull(em.emID),
                                             @"exclusive": @(isExclusive), ...

I also don't suspect you meant to use BOOL * as your parameter. You presumably intended:

- (void)postPrimaryEMWithEM:(EM *)em
                  exclusive:(BOOL) isExclusive
                    success:(void (^)())onSuccess
                    failure:(void (^)())onFailure {
    ...
}

Again, a BOOL is not an object, so the * syntax was presumably not intended.
