Question

I am looking for some help for a program I am developing. Basically, it contains two views. The first view has a button and a action related to it leads me to my next view where there is a scroll view for three pages ( as in the PageControl sample given by apple.) I am using navigation controller to push the view from the first view to the second view. But on pushing I am not able to scroll the page or using page control or anything. It just comes a normal view. The code is same as pageControl code and it works fine as a separate module. But when I want to integrate this pageControl code with a first view and a click button it doesn’t work. Please help.

//this function is an action set against a button in the rootviewcontroller.

-(IBAction) viewScrollPages:(id)sender{
UIViewController *controller = [[MyViewController alloc] initWithPageNumber:0];
[self.navigationController pushViewController:controller animated:NO];
[controller release];

}

- (id)initWithPageNumber:(int)page {
if (self = [super initWithNibName:@"MyViewController" bundle:nil]) {
    pageNumber = page;
}   
return self;

}

- (void)viewDidLoad {   
NSMutableArray *controllers = [[NSMutableArray alloc] init];
for (unsigned i = 0; i < kNumberOfPages; 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 * kNumberOfPages, scrollView.frame.size.height);
scrollView.showsHorizontalScrollIndicator = NO;
scrollView.showsVerticalScrollIndicator = NO;
scrollView.scrollsToTop = NO;
scrollView.delegate = self;
pageControl.numberOfPages = kNumberOfPages;
pageControl.currentPage = 0;
// 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];
pageNumberLabel.text = [NSString stringWithFormat:@"Page %d", pageNumber + 1];
self.view.backgroundColor = [MyViewController pageControlColorWithIndex:pageNumber];
[super viewDidLoad];

}

It sounds like your pushing a normal view that is a subview of the scrollview instead of pushing the scrollview itself.
