Summary:
I am using iOS 8 self-sizing cells (tableView.rowHeight = UITableViewAutomaticDimension and tableView:estimatedHeightForRowAtIndexPath:) combination. It works great until I start typing something inside a cell. When I'm typing, I'm calling beginUpdates/endUpdates pair to resize my cell (text view grows as I type and shrinks as I delete) but each call results in a bad jump to top of the table view. If I remove the beginUpdates/endUpdates pair then it doesn't jump but my cell doesn't resize as I type.

We figured out we could check and only update the table when the size actually needs to change via:
// Resize cell only when cell's size is changes
        if size.height != newSize.height
        {

so it only jumps when the cell gets bigger but it still jumps. 

I attached the project, also available here on Github - https://github.com/joshdance/TableViewJumpIssue

Steps to Reproduce:
1. Tap in the cell
2. Start entering text


Expected Results:
I would expect the tableView not to jump to the top when it gets resized. Or maybe a parameter to set where I could set a scroll location it would stay at while the table is updating. 

Actual Results:
Calling the beginUpdates/endUpdates pair to resize my cell but each call results in a bad jump to top of the tableView. 

Version:
iOS 8.2

Configuration:
