Ideas on getting a cell's center and set it as a value of the center of a UIView
===

I'm currently working on a drag and drop functionality and luckily I found a good [tutorial](http://www.scott-sherwood.com/?p=514). The goal of this project is to drag and drop "items" from one table view to another with the help of the `UILongPressGestureRecognizer`. As I have learned from this, you have to get a "snapshot" of a cell you chose in able to get the feel of dragging something out of a table. And I think, below is the method that does this.

    - (void)dragAndDropTableViewController:(DragAndDropTableVC *)ddtvc draggingGestureWillBegin:(UIGestureRecognizer *)gesture forCell:(UITableViewCell *)cell
    {
        // create a snapshot of the cell
        NSLog(@"draggable delegate method is called");
        UIGraphicsBeginImageContext(cell.contentView.bounds.size);
        [cell.contentView.layer renderInContext: UIGraphicsGetCurrentContext()];
        UIImage *cellImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        
        UIImageView *cellImageView = [[UIImageView alloc] initWithImage:cellImage];
        self.dragAndDropView = [[UIView alloc] initWithFrame:cellImageView.frame];
        [self.dragAndDropView addSubview:cellImageView];
        [self.dragAndDropView setBackgroundColor:[UIColor blueColor]];
        [self.dragAndDropView setCenter:[gesture locationInView:self.view.superview]];
        
        [self.view.superview addSubview:self.dragAndDropView];
    }

Basically, upon getting the cell's "snapshot", you have to add it as a subview of a UIView. The thing that bugs me out is this part.

`[self.dragAndDropView setCenter:[gesture locationInView:self.view.superview]];`

This may sound easy but what I would want to do is when the long press is done, the draggable cell should appear a bit higher than the original location of the selected cell. 

Enlighten me please :) Thanks!
