iPhone: Getting Returned Data from MGTwitterEngine?

Question

I call a method on the _engine and implement the requestSucceeded. I then print out the resuls and it makes no since to me. What may I be doing wrong? Can't figure it out.

Call in my code:

[_engine getRateLimitStatus];

Method that gets called when succesful:

- (void)requestSucceeded:(NSString *)requestIdentifier{
    NSLog(requestIdentifier);
}

Console:

CAA5AD3C-217D-4298-9ABC-20308816E4EB

Thanks to all that reply!!
