Thanks for this post. It helped me a great deal. In my case I am also editing the text in a separate view controller. I noticed that when I use:

[cell.contentView addSubview:cellLabel];

in the tableView:cellForRowAtIndexPath: method that the label view was continually rendered over the top of the previous view each time I edited the cell. The text became pixelated, and when something was deleted or changed, the previous version was visible under the new version. Here's how I solved the problem:

if ([[cell.contentView subviews] count] > 0) {
    UIView *test = [[cell.contentView subviews] objectAtIndex:0];
    [test removeFromSuperview];
}
[cell.contentView insertSubview:cellLabel atIndex:0];

No more weird layering. If there is a better way to handle this, Please let me know.
