UITableView: custom gestures make it scrolling no

Question

I have an UIViewController which contains a UITableView (subclassed) and another UIView (subclassed). They are on the same hierarchy level but the UIView is added last so it is the frontmost. I overrid touchesBegan/Moved/Ended to intercept the Gestures from the top UIView: my goal is to get the selected UITableViewCell and, if double tapped, create an ImageView to be dragged around. I appear to get it done but now I cannot scroll the UITableView anymore, even though I forward the touch events. Here are the methods for the UIView:

    - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"BO");
    UITouch * touch = [touches anyObject];

    CGPoint tPoint = [touch locationInView:self];
    InventoryViewController * invViewCont = self.viewController;
    UITableView * invTab = invViewCont.inventoryTableView;
    [invTab deselectRowAtIndexPath:[invTab indexPathForSelectedRow] 
                          animated:YES];
    NSArray * cells = [invTab visibleCells];
    BOOL found = NO;
    for (UITableViewCell * cell in cells)
    {
        if (CGRectContainsPoint(cell.frame, tPoint)) 
        {
            [cell touchesBegan:touches withEvent:event];
            found = YES;
            break;
        }
    }


    if (!found)
    {
        [invViewCont.inventoryTableView touchesBegan:touches withEvent:event];
    }
}
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
        NSLog(@"Mo");
        UITouch * touch = [touches anyObject];
        CGPoint tPoint = [touch locationInView:self];

        copyObj.center = tPoint;
        InventoryViewController * invViewCont = self.viewController;
        UITableView * invTab = invViewCont.inventoryTableView;

        [invTab deselectRowAtIndexPath:[invTab indexPathForSelectedRow] 
                              animated:YES];
        NSArray * cells = [invTab visibleCells];
        BOOL found = NO;
        for (UITableViewCell * cell in cells)
        {
            if (CGRectContainsPoint(cell.frame, tPoint)) 
            {
                [cell touchesMoved:touches withEvent:event];
                found = YES;
                break;
            }
        }

        if (!found)
        {
            [invViewCont.inventoryTableView touchesMoved:touches withEvent:event];
        }

    }

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

        UITouch * touch = [touches anyObject];
        if ([touch tapCount] == 2) 
        {
            [self desubCopyView];
        }
        CGPoint tPoint = [touch locationInView:self];
        copyObj.center = tPoint;
        InventoryViewController * invViewCont = self.viewController;
        UITableView * invTab = invViewCont.inventoryTableView;
        [invTab deselectRowAtIndexPath:[invTab indexPathForSelectedRow] 
                              animated:YES];
        NSArray * cells = [invTab visibleCells];
        BOOL found = NO;
        for (UITableViewCell * cell in cells)
        {
            if (CGRectContainsPoint(cell.frame, tPoint)) 
            {
                [cell touchesEnded:touches withEvent:event];
                //[cell.imageView touchesEnded:touches withEvent:event];
                found = YES;
                break;
            }
        }
        if (!found)
        {
            [invViewCont.inventoryTableView touchesEnded:touches withEvent:event];
        }
    }

And here are those in the UITableViewCell

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    UITouch * touch = [touches anyObject];
    if ([touch tapCount] == 2) 
    {
        CGPoint tPoint = [touch locationInView:self]; 
        NSLog(@"CellX %lf CY %lf", tPoint.x, tPoint.y);

        UIGraphicsBeginImageContext(self.bounds.size);
        [self.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();

        UIGraphicsEndImageContext();

        UIImageView * newView = [[UIImageView alloc] initWithImage:viewImage];
        [dragArea addSubview:newView];
        dragArea.copyObj = newView;
        [newView release];

        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDuration:0.4];
        dragArea.copyObj.transform = CGAffineTransformMakeScale(1.3, 1.3);
        [UIView commitAnimations];
        tPoint = [self convertPoint:tPoint toView:dragArea];
        dragArea.copyObj.center = tPoint;
    }
    [super touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"MOV %@", self.imageView.image);
    [super touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"ENDED");
    [super touchesEnded:touches withEvent:event];
}

And in my UITableView I have simply:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"BEGTB");
    [super touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event{
    NSLog(@"MOVTB");
    [super touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
        NSLog(@"ENDTB");
    [super touchesEnded:touches withEvent:event];
}

I am surely missing something but I do not know what

Answer 1

I would highly recommend looking into UITapGestureRecognizer instead of handling the touchesX events yourself.

Answer 2

I found a workaround for this, override the methods for touch gestures in my custom UITableView in order to make it scroll programMatically as I drag upon it an object. Here is the 'solution'.

I still believe there is another simpler way to do this but I did not find it, so posting this and marking it as an 'answer' might help someone else.
