Why does the Parse.com Join Table not work? - ios

Question

I use this code for the Table View:
#implementation FollowerTableViewController
- (instancetype)initWithStyle:(UITableViewStyle)style {
self = [super initWithStyle:style];
if (self) { // This table displays items in the Todo class
self.parseClassName = #"FriendClass";
self.pullToRefreshEnabled = YES;
self.paginationEnabled = YES;
self.objectsPerPage = 25;
}
return self;
}
- (PFQuery *)queryForTable {
PFQuery *query = [PFQuery queryWithClassName:self.parseClassName];
[query whereKey:#"to" equalTo:[PFUser currentUser]];
// If no objects are loaded in memory, we look to the cache first to fill the table
// and then subsequently do a query against the network.
if (self.objects.count == 0) {
query.cachePolicy = kPFCachePolicyCacheThenNetwork;
}
[query orderByDescending:#"date"];
return query;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
static NSString *cellIdentifier = #"cell1";
PFTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell) {
cell = [[PFTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:cellIdentifier];
}
// Configure the cell to show todo item with a priority at the bottom
cell.textLabel.text = object[#"from"];
NSLog(#"%#", object[#"from"]);
//cell.detailTextLabel.text = [NSString stringWithFormat:#"Priority: %#", object[#"priority"]];
NSLog(#"%# , %#", object[#"from"], object[#"to"]);
return cell;
}
#end
And this I uploaded before:
-(void)follow {
// suppose we have a user we want to follow
PFUser *otherUser = (PFUser *)textField.text;
NSLog(#"%#", otherUser);
// create an entry in the Follow table
PFObject *follows = [PFObject objectWithClassName:#"FriendClass"];
[follows setObject:[PFUser currentUser] forKey:#"from"];
[follows setObject:otherUser forKey:#"to"];
[follows setObject:[NSDate date] forKey:#"date"];
[follows saveInBackground];
}
any idea why it doesn't work.
