Parse: Find number of objects found in query

How do I find the number of objects found in a query? The following code is always printing "0", but there is a user with that username in the database.

PFQuery *query = [PFQuery queryWithClassName:@"User"];
    [query whereKey:@"username" equalTo:self.usernameField.text];
    [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
        if ([objects count] == 0) {
            NSLog(@"error %lu", (unsigned long)[objects count]);
        }
        else {
            NSLog(@"no error");
        }
    }];

What am I doing wrong?

Performing a query on the _User class should be done using the +query method of the PFUser class

PFQuery *userQuery = [PFUser query];   //Note the difference here.
[userQuery findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error)    {
   if ([objects count] == 0) {
        NSLog(@"error %lu", (unsigned long)[objects count]);
    }
    else {
        NSLog(@"no error");
    }
}];

Try This , Because parse default user entity is initiated with "_User"

PFQuery *query = [PFQuery queryWithClassName:@"_User"];

[query whereKey:@"username" equalTo:self.usernameField.text];

[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error)    {

   if ([objects count] == 0) {
        NSLog(@"error %lu", (unsigned long)[objects count]);
    }
    else {
        NSLog(@"no error");
    }
}];
