Jump to a specific/last page in a uiscrollview?

Have a UIScrollView setup here with multiple horizontal pages, and I'd like to add a button to move to the last page of the scrollview, as it might have over 1000 pages.

I thought scrollRectToVisible:Animated: might be the way to go, but I added that to viewWillAppear and with the scrollviews bounds as parameter but it doesn't seem to do anything.

Any ideas?

 

Here's my viewWillAppear:

Code:

- (void)viewWillAppear:(BOOL)animated {
    // view controllers are created lazily
    // in the meantime, load the array with placeholders which will be replaced on demand
    NSMutableArray *controllers = [[NSMutableArray alloc] init];
    for (unsigned i = 0; i < pages; i++) {
        [controllers addObject:[NSNull null]];
    }
    self.viewControllers = controllers;
    [controllers release];

    // a page is the width of the scroll view
    scrollView.pagingEnabled = YES;
    scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * pages, scrollView.frame.size.height);
    scrollView.showsHorizontalScrollIndicator = NO;
    scrollView.showsVerticalScrollIndicator = NO;
    scrollView.scrollsToTop = NO;
    scrollView.delegate = self;

    // pages are created on demand
    // load the visible page
    // load the page on either side to avoid flashes when the user starts scrolling
    [self loadScrollViewWithPage:0];
    [self loadScrollViewWithPage:1];
	
	CGRect rootViewBounds = self.parentViewController.view.bounds;
	CGFloat rootViewHeight = CGRectGetHeight(rootViewBounds);
	CGFloat rootViewWidth = CGRectGetWidth(rootViewBounds);
	pageLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, (rootViewHeight - 20), rootViewWidth, 20)];
	[pageLabel setBackgroundColor:[UIColor blackColor]];
	[pageLabel setTextColor:[UIColor whiteColor]];
	[pageLabel setTextAlignment:UITextAlignmentCenter];
	pageLabel.text = [[NSString stringWithFormat:@"1 of %i",pages] retain];
	[self.navigationController.view addSubview:pageLabel];	
//	[self.scrollView scrollRectToVisible:HELPZ animated:YES];
}

 

That worked perfectly! I see now where I went wrong.
