Change data source of tableView after selected row

I have table view with rows...after I selecting one item I want to show tableView with a new data source.

I tried to implement:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

[self.searchDisplayController setActive:YES animated:YES];
    Game *game = [self.filteredListContent objectAtIndex:indexPath.row];
    //name your class names with capitals
    NSMutableArray *arrayToBeAdded= [[NSMutableArray alloc]initWithArray:newgamearray];
    [ListContent removeAllObjects];
    [ListContent addObject:arrayToBeAdded];

but I getting exeption in the 

[ListContent removeAllObjects];

Implementation of the init:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellID = @"cellSgames";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellID];

    if (cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellID] autorelease];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }

    Gmage *game = [self.ListContent objectAtIndex:indexPath.row];

In the .h file i declare:

NSArray AllList;
NSMutableArray ListContent;

any ideas?

Normally if you are resetting the array in didselect method and reloading your table view with new content it should work.

In your case i think at line: [ListContent removeAllObjects];

ListContent is not a valid pointer. I don't see a reason to crash it here.

Instead of manipulating the current list, create new UITableViewController with your desired data source. If you are using the UINavigationController it will create a better user experience and you will avoid your current problem.

Example:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
    InnerTableViewController *innerTVC = [[InnerTableViewController alloc] initWithNibName:@"InnerTableViewController" bundle:nil];

    [self.navigationController pushViewController:innerTVC animated:YES];
    [innerTVC release];
}
