Centering UIImageView in UItableViewCell doesn't work, how to fix?

I can subclass the cell and resolve the problem, but I'd like to know why this doesn't work.

I set an image in the cell, then in this method, I move the image to the right:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
        [cell.imageView setFrame:CGRectMake(cell.contentView.bounds.size.width/2 - cell.imageView.frame.size.width/2 + 100,
                                            cell.contentView.bounds.size.height/2 - cell.imageView.frame.size.height/2,
                                            cell.imageView.frame.size.width,
                                            cell.imageView.frame.size.height)];
        NSLog(@"center: %@", NSStringFromCGPoint(cell.imageView.center));
        NSLog(@"frame: %@", NSStringFromCGRect(cell.imageView.frame));
}

Notice the +100 I added to ensure it's over to the right.

When I check the console, it indicates this:

center: {250, 57.5}

frame: {{150, 7.5}, {200, 100}}

However the output is this:

grouped cell image

The image is still aligned to the left side. Can this be changed, and if so, how?

You can not move the image view. Solution is or to subclass and do your own drawing in drawRect, or to add a subview to the cell.contentView.

Edit:

If an image is set, it appears on the left side of the cell, before any label. UITableViewCell creates the image-view object when you create the cell.

if you go to the header file of UITableViewCell than there you will find...

> // Content.  These properties provide direct access to the internal
> label and image views used by the table view cell.  These should be
> used instead of the content properties below.
> @property(nonatomic,readonly,retain) UIImageView  *imageView
> __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_3_0);   // default is nil.  image view will be created if necessary.

so as you can see it says readOnly property to the image view... I think this explains your inability to move the imageView.
