How to keep UITableView contentoffset after calling -reloadData

CGPoint offset = [_table contentOffset];
[_table reloadData];
[_table setContentOffset:offset animated:NO];    //unuseful

//    __block UITableView *tableBlock = _table;
//    [self performBlock:^(id sender) {
//        [tableBlock setContentOffset:offset];
//    } afterDelay:2];

I know don't know of any delegate method which gets called after reloadData. And using afterDelay:2 which is kind of a hack may be too short or too long, so how can I implement it?

Solution

  • I was recently working with reloadData -- reloadData doesn't change the contentOffset or scroll the table view. It actually stays the same if the offset is less than the new amount of data.
