Here's a workaround that works for me.

-(IBAction)showDropDownList:(id)sender
{

tableView = [[UITableView alloc] initWithFrame:CGRectMake(7, 135, 200, 0) style:UITableViewStyleGrouped];
        tableView.delegate = self;
        tableView.dataSource = self;

    if (tableState == TableViewStateClosed) {  //enum for identifying tableview state

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.3];
        CGRect viewRect = self.tableView.frame;
        viewRect.size.height += 150;

        [self.tableView setFrame:CGRectMake(7, 135, 200, viewRect.size.height)];

        [UIView commitAnimations];
        [self.view addSubview:tableView];
        tableState = TableViewStateOpen;
    }
    else if (tableState == TableViewStateOpen) {

        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationDuration:0.3];

        [self.inboxTableView setFrame:CGRectMake(7, 135, 200, 0)];

        [UIView commitAnimations];

        tableState = TableViewStateClosed;
    }
}
