Having Trouble to select row in UITableviewCell

Friend I've been trying to set default Checkmark in my UITableView Cell,Here is my code please look at this, I'm having serious trouble to get my desire output

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdent = @"cell1111";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdent];
if (tableView==_ShapeSelectionTable)
{

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [_ShapeSelectionTable dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

    }

    if([_selectedShapeArray containsObject:[_shapeArray objectAtIndex:indexPath.row]] || [_selectedShapeArray containsObject:@"Check All"]) {

        cell.accessoryType = UITableViewCellAccessoryCheckmark;

    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
  for (NSString *s in _shaperesultArray)
    {
        for (int i=0; i<self.shapeArray.count; i++)
        {
        NSIndexPath *myIdx=[NSIndexPath indexPathForRow:i inSection:0];
         ShapeInfo *shap=[self.shapeArray objectAtIndex:i];


            if ([shap.shape isEqualToString:s])
            {


                cell = [[self ShapeSelectionTable] cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];
                cell.accessoryType=UITableViewCellAccessoryCheckmark;
 //[tableView selectRowAtIndexPath:myIdx animated:TRUE scrollPosition:UITableViewScrollPositionNone];
 }
            else
            {
                cell.accessoryType=UITableViewCellAccessoryNone;
            }

        }
    }
 ShapeInfo *shap=[_shapeArray objectAtIndex:indexPath.row];

    cell.textLabel.text=shap.shape;

    return cell;
}

I want to get following output From my ResultInfo is , Cell should remember accessory type enter image description here

I guest this exception happen at this line of code 

 cell = [[self ShapeSelectionTable] cellForRowAtIndexPath:[NSIndexPath indexPathForRow:i inSection:0]];

You should put some break point here and simulate what is happening.

You shouldn't call -selectRowAtIndexPath:animated: in -cellForRowAtIndexPath:, you don't have to select a row to show a check mark.
