RKObjectManager mapping results issue

I am trying to store the results from [[RKObjectManager sharedManager] getObjectsAtPath:@"/groups" ... in an array and am wondering why the array is not storing my object outside of my getObjectsAtPath?

@property (strong, nonatomic) NSArray *groups;

- (void)loadGroups
{

[[RKObjectManager sharedManager]  getObjectsAtPath:@"/groups"  parameters:nil     
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
    [self.refreshControl endRefreshing];

    self.groups = mappingResult.array;
    NSLog(@"GROUP COUNT INSIDE %@", [NSString stringWithFormat:@"%d", _groups.count]);
    NSLog(@"GROUP NAME INSIDE %@",[self.groups objectAtIndex:0]);
    NSLog(@"GROUP NAME INSIDE %@",[[self.groups objectAtIndex:0] valueForKey:@"groupName"]);
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
    [self.refreshControl endRefreshing];
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"An Error Has Occurred" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alertView show];
}];

NSLog(@"GROUP NAME OUTSIDE %@",[self.groups objectAtIndex:0]);
NSLog(@"GROUP NAME OUTSIDE %@",[[self.groups objectAtIndex:0] valueForKey:@"groupName"]);
NSLog(@"GROUP COUNT OUTSIDE %@", [NSString stringWithFormat:@"%d", self.groups.count]);
}

NSLOG output:

2013-11-10 12:04:33.294 Test[64618:11603] GROUP NAME OUTSIDE (null)

    groupName = Admin;

When you say "outside of getObjectsAtPath", you really mean outside of the success block. The reason is simply that the success block hasn't run yet so your property has not had a value set yet. This is because the call to getObjectsAtPath is asynchronous and could take tens of seconds to obtain the requested data. You shouldn't expect the data to be available until the success block has been called. (Calling getObjectsAtPath doesn't block the thread until it has completed).
