UIScrollView+PagingEnabled

[JohnMabassa]

Hi,
I was trying to make an application where there is a table with names of some items and when you click on one item, a new view with the details will be shown, now I donot want the user to go back to the tableview again and select the next item to see its details. I want to implement a scrollView with paging so that the user can swipe through all the items without going back.

I have used some codes from "Iphone Noob viewing images as photos.app" and was able to make it work. Now the problem is that even if I click the first item or the second item.... the detail view starts with the details of first item. I am not sure how to fix this issue.

Please find some relevant codes

When I click on an item I am loading the scroll view and passing the array with list of items and its details.

ScrollViewController.m

- (void)viewDidLoad {

    self.title=@"List Of Items";
	NSMutableArray *controllers = [[NSMutableArray alloc] init];
	
	for (unsigned i = 0; i < [self.detailsArray count]; 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 * [self.detailsArray count], scrollView.frame.size.height);
	scrollView.showsHorizontalScrollIndicator = NO;
	scrollView.showsVerticalScrollIndicator = NO;
	scrollView.scrollsToTop = NO;
	scrollView.delegate = self;
	
	
	[self loadPage:0];
	[self loadPage:1];
}

- (void)loadPage:(int)page {
	if (page < 0) return;
	if (page >= [self.detailsArray count]) return;//detailsArray has the entire list of items
	
	// replace the placeholder if necessary
	DetailedViewController *controller = [viewControllers objectAtIndex:page];
	if ((NSNull *)controller == [NSNull null]) {
		
		NSDictionary *itemAtIndex = (NSDictionary *)[self.detailsArray objectAtIndex:page];
		
		controller = [[DetailedViewController alloc] initWithDictionary:itemAtIndex];
		
		[viewControllers replaceObjectAtIndex:page withObject:controller];
		[controller release];
	}
	

	if (nil == controller.view.superview) {
		CGRect frame = scrollView.frame;
		frame.origin.x = frame.size.width * page;
		frame.origin.y = 0;
		controller.view.frame = frame;
		[scrollView addSubview:controller.view];
		//[scrollView scrollRectToVisible:frame animated:NO];
	}
}

- (void)scrollViewDidScroll:(UIScrollView *)sender {

	CGFloat pageWidth = scrollView.frame.size.width;
	int page = floor((scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
	

	[self loadPage:page - 1];
	[self loadPage:page];
	[self loadPage:page + 1];
}

It will be helpful if I could get some tutorials or sample codes?

Thanks

figured it out with the help of skyLarEC (ipodtouchfans). I need to use setContentOffset method.
