Answer 1

Override in your UITableView class this method

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
 {

     if(((UITouch *)[touches anyObject]).tapCount == 2)
    {
    NSLog(@"DOUBLE TOUCH");
    }
    [super touchesEnded:touches withEvent:event];
}

If you do not want to create a subclass of UITableView, use a timer with the table view's didSelectRowAtIndex:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    //checking for double taps here
    if(tapCount == 1 && tapTimer != nil && tappedRow == indexPath.row){
        //double tap - Put your double tap code here
        [tapTimer invalidate];
        [self setTapTimer:nil];

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Double Tap" message:@"You double-tapped the row" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
        [alert show];
        [alert release];
    }
    else if(tapCount == 0){
        //This is the first tap. If there is no tap till tapTimer is fired, it is a single tap
        tapCount = tapCount + 1;
        tappedRow = indexPath.row;
        [self setTapTimer:[NSTimer scheduledTimerWithTimeInterval:0.2 target:self selector:@selector(tapTimerFired:) userInfo:nil repeats:NO]];
    }
    else if(tappedRow != indexPath.row){
        //tap on new row
        tapCount = 0;
        if(tapTimer != nil){
            [tapTimer invalidate];
            [self setTapTimer:nil];
        }
    }
}

- (void)tapTimerFired:(NSTimer *)aTimer{
    //timer fired, there was a single tap on indexPath.row = tappedRow
    if(tapTimer != nil){
        tapCount = 0;
        tappedRow = -1;
    }
}
