Keep uitableview static when inserting rows at the top

Question

Whilst I\'m doing this I want the current view to stay completely still, so the rows only appear if you

Answer 1

Based on Andrey Z's answer, here is a live example working perfect for me...

int numberOfRowsBeforeUpdate = [controller.tableView numberOfRowsInSection:0];
CGPoint currentOffset = controller.tableView.contentOffset;

if(numberOfRowsBeforeUpdate>0)
{
    [controller.tableView reloadData];
    int numberOfRowsAfterUpdate = [controller.tableView numberOfRowsInSection:0];

    float rowHeight = [controller getTableViewCellHeight];  //custom method in my controller
    float offset = (numberOfRowsAfterUpdate-numberOfRowsBeforeUpdate)*rowHeight;

    if(offset>0)
    {
        currentOffset.y = currentOffset.y+offset;
        [controller.tableView setContentOffset:currentOffset];
    }
}
else
    [controller.tableView reloadData];
