if you want to select Multiple rows and add objects to your array i suggest to create 2 NSMutableArray the first one contains all data and the other the selected rows data.

@property (strong , nonatomic) NSMutableArray *myalldatatab;
@property (strong , nonatomic) NSMutableArray *selecteddata;

then use didselectrowsatindexpath and didDeselectRowAtIndexPath to change the mark

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
}

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
    [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryNone;
}

and you can get indexes of selected rows by calling this line :

NSArray *selectedCells = [self.tableView indexPathsForSelectedRows];

you can now iterate selected cells and add objects like this

for (int i = 0; i < [selectedCells count]; i++)
        {
[self.selecteddata addObject: [selectedCells objectAtIndex:i]]
}

Hope it help you :)) happy c0de !!
