You have to keep track of the state (or height) of the expanding/collapsing cell. Then report that height in tableView:heightForRowAtIndexPath:. Then add the code below to trigger the resizing.

[self.tableView beginUpdates];
[self.tableView endUpdates];

For example:

- (void)toggleMapCell {
    _mapCellExpanded = !_mapCellExpanded;
    if (_mapCellExpanded)
        _mapCellHeight = 200.0;
    else
        _mapCellHeight = 44.0;
    [self.tableView beginUpdates];
    [self.tableView endUpdates];
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    if ([indexPath isEqualTo:_mapCellIndexPath])
        return _mapCellHeight;
    else
        return 44.0;
}

If you have to re-layout the cell's content. I think the best place is to do it in the cell's layoutSubviews.
