Passing data from PFQueryForTableViewController cell through segue to viewController - ios

Question

so I am trying to pass data from my cell (populated with queryForTable method) through a segue to another viewController. I am using the prepareForSegue method and my code looks like:
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"profile"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
PFObject *object = [self.objects objectAtIndex:indexPath.row];
//UINavigationController *nav = [segue destinationViewController];
ProfileViewController *userProfile = [segue destinationViewController]; //(ProfileViewController *) nav.topViewController;
userProfile.userInfo = object;
}
}
in my VC I have the property defined:
#property (weak, nonatomic) PFObject *userInfo;
but when I run my code I get the error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController setUserInfo:]:

It looks like the viewController you're pulling out of the segue isn't a ProfileViewController - the error you're getting states:
-[UIViewController setUserInfo:]:
Note UIViewController, not ProfileViewController. This would seem to indicate that your segue's destination viewController isn't exactly what you think it is.
Check your destination viewController's class in your Storyboard. Is it set to ProfileViewController? Is your ProfileViewController embedded inside another viewController (like a navigationController - looking at your commented out code, you seem to have treated it as such before)? If so, you might need to do a big more digging to get a reference to the correct viewController.
