Multi Touch problem in Custom UiTableViewCell

static NSString *cellIdentifier = @"Cell";
AssignmentTableCell *cell = (AssignmentTableCell *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell == nil) {
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AssignmentTableCell" owner:self options:Nil];
    cell = [nib objectAtIndex:0];
}

Here is my Code for custom Cell initialization. I am detecting uitouch for custom cells and then i am pushing view controller rather than using DidSelected Event of the UItableView. But problem i am facing is

I can select 2 rows at a time, which is not my intension and that leads to application crash. I have tried to disable multitouch but of no use. they still keep selecting 2 cells at a time.

Any Help will be appreciated.

Edit 1:

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    imgBg.image = [UIImage imageNamed:@"rowSelected.png"];
    [[self delegate] touchStarted:tag];
}

-(void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
    imgBg.image = [UIImage imageNamed:@"7CustomCellBackground.png"];
    [[self delegate] touchEnded:tag];
}

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    //imgBg.image = [UIImage imageNamed:@"7CustomCellBackground.png"];
    [[self delegate] rowTocuchedFromClicked:tag];
}

Here are the touches method of the cell.

Can you add some code regarding how you are detecting touches on the cell? Also, the reason you are seeing multiple selections in because you are not de-selecting the selected cell. Do something like-

-(void) tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath)indexPath
{
    [tableView deselectRowAtIndexPath: indexPath animated: YES];
    //your other stuff
}

The reason for the crash is something else, which can only be ascertained after you paste the console logs.
