Display array from parse.com in tableview (iOS)

Question

I am tying to display in my table view an array that is on a database on parse.com I can display the first item in the array, but not the rest.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell==nil){
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }   
    _ListArray = [object objectForKey:@"content"];
    NSLog(@"OBJECT = %@",_ListArray);
    NSString *cellValue = [NSString stringWithFormat:@"%@", [_ListArray objectAtIndex:indexPath.row]];

    cell.textLabel.text = cellValue;

    if(refresh <counter)
    {
        NSString *br = @"<br>";
        List = [NSString stringWithFormat:@"%@%@%@", List, br, cell.textLabel.text];
        NSLog(@"%@",List);
        refresh ++;
    }       
    cell.accessoryType =UITableViewCellAccessoryDisclosureIndicator;

    return cell;
}

If I try to use:

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [_ListArray count];
}

I get nothing in the table.

edit update:

did remove the self.ListArray and going with _ListArray.

in the h file:

NSMutableArray *ListArray;
...
@property (retain, atomic) NSMutableArray *ListArray;

and then in m file:

@synthesize ListArray = _ListArray;

regarding the:

self.ListArray = [object objectForKey:@"content"];

the object is the PFObject.

i have queryForTable where i get the data from parse.

- (PFQuery *)queryForTable {

    PFQuery *query = [PFQuery queryWithClassName:@"List"];
    [query whereKey:@"user" equalTo:[PFUser currentUser]]; // user
    [query whereKey:@"objectId" equalTo:[theListID objectId]]; // the specific list
    counter =[query countObjects];
    NSLog(@"%d",counter);

    // If Pull To Refresh is enabled, query against the network by default.
    if (self.pullToRefreshEnabled) {
        query.cachePolicy = kPFCachePolicyNetworkOnly;
    }

    // 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:@"createdAt"];

    return query;

}

And to the objectForKey:@"content"]; content is the name of the column in my class on parse so i need to say what object from the class i want to get, and that is the array column named "content"

The logg, (when the NSLog is active on the array.

Please check what value comes in self.ListArray when you reload data — iEinstein

What is the purpose of self.ListArray = [object objectForKey:@"content"]; ? If you're using the parse provided table view controller you just need to configure the cell for the passed object... — Wain

Did edit the post for more info. and in the storyboard the identifier is "Cell". — Nivres

Got it to work, did put the array were i get the data from parse, and then only call

cell.textLabel.text = [_ListArray objectAtIndex:indexPath.row];

and then i can use:

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [_ListArray count];
}
