Checking for zero length array from JSON set

Question

I have JSON data set returned that I am parsing.

If the data contains a record it looks like this:

dictData: {
    Recordset =     (
                {
            Record = (
                                {
                    MyDate = "2016-06-15 11:04:43";
                    MyID = 53070;
                    SomeDescription = "";

                }
            );
        }
    );
}

If the data does NOT contains a record it looks like this: Notice the "" in the return set which is causing me issues.

dictData: {
    Recordset =     (
        ""
    );
}

I am having trouble accounting for the zero length array in the Recordset.

Here is my base code for parsing the data.

NSDictionary * dictData = [NSDictionary dictionaryWithDictionary:[someOtherDictionary objectForKey:@"Data"]];
NSArray * arrRecordSet  = [dictData objectForKey:@"Recordset"];

if([arrRecordSet objectAtIndex:0] != nil) {
    NSLog(@"CONTAINS RECORDS");
    //Do something with the records
}
else {
    NSLog(@"DOES NOT CONTAIN RECORDS");
}

I have tried various iterations of things like checking if [arrRecordSet objectAtIndex:0] length is greater than zero or checking the count size.

I think the double quotes are throwing me off.

Any help?

UPDATE

RAW JSON as requested

ONE RECORD

{
    APIResponse =     {
        Data =         {
            Recordset =             (
                                {
                    Record =                     (
                                                {
                            MyDate = "2016-06-15 11:04:43";
                            MyID = 53070;
                            SomeDescription = "";
                        }
                    );
                }
            );
        };
    };
}

NO RECORDS

{
    APIResponse =     {
        Data =         {
            Recordset =  (
                               ""
            );
        };
    };
}

So in the case of success the Recordset value is an array with a dictionary and in the case of failure the Recordset value is an array with a string.

So:

NSArray *recordSet = response[@"APIResponse"][@"Data"][@"Recordset"];
if ([recordSet count] > 0 &&
    [recordSet[0] isKindOfClass:[NSDictionary class]]) {
    // Success
    NSDictionary *record = recordSet[0];
    ...
} else {
    // Failure
}
