CoreData with NSNumber

Question

I've create a sqlite CoreData Application with multiple records inside:

myFile.h

@property (nonatomic, retain) NSNumber * game;
@property (nonatomic, retain) NSString * image;
@property (nonatomic, retain) NSString * name;
@property (nonatomic, retain) NSNumber * result;
@property (nonatomic, retain) NSNumber * totalWin;

myFile.m

@dynamic game;
@dynamic image;
@dynamic name;
@dynamic resul;
@dynamic totalWin;

And i read all in UITableView custom, but i will in the first page get a general report for all game, for example:

If i played 5 games i have 5 cells in my UITableView how can get the total amount in a unique NSNumber like a:

UILabel *myTotal;
myTotal = //here i want to get total game from all my cells

And in the 5 cells have a NSNumber game:

 1St game = 5 2St game = 3 3St game = 4 4St game = 6 5St game = 1 

How show in the firsrt page one label with this amount 19

This is what i load in to a TableView:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

    return [archive count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
    }

    UILabel *gameName = (UILabel *)[cell viewWithTag:2];
    gameName.text = [archive[indexPath.row]name];

    int gameInt = [[archive [indexPath.row] game]intValue];
    UILabel *gameValue = (UILabel *)[cell viewWithTag:3];
    gameValue.text = [NSString stringWithFormat:@"%d",gameInt];

    return cell;
}

solved with Larme code thanks

Try [archive valueForKeyPath:@"@sum.game"]; (or replace game, by resul, totalWin or whatever you want).
