iphone - setContentOffset only works if animated is set to YES

Question

I have a UITableView which I would like to be displayed 100px down. For some reason this only works when animated is set to YES. Why is this?

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    /*[self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0] 
                          atScrollPosition:UITableViewScrollPositionNone 
                                  animated:NO];*/

    /*[self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathWithIndex:1] 
                                        atScrollPosition:UITableViewScrollPositionNone 
                                        animated:NO];*/

    [self.tableView setContentOffset:CGPointMake(0,100) animated:YES];
}

Answer 1

Using the base Navigation-based Application that XCode supplies and giving it some table cells, it works fine with what you've given. Have you tried setting the content offset within viewDidAppear rather than viewWillAppear?
