Hi! Make a new subclass of UIViewController, for example "PageViewController", and programmatically add the required views.

I stripped the code down to the smallest possible working example, but you will need to take care of memory leaks etc.

#import <UIKit/UIKit.h>

@interface PageController : UIViewController {
	UIImageView *imageView;
	UITextView  *textView;

@property (nonatomic, retain) UIImageView *imageView;
@property (nonatomic, retain) UITextView  *textView;

#import "PageController.h"

@implementation PageController

@synthesize imageView;
@synthesize textView;

- (void)loadView {
	UIScrollView *contentView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
	[contentView setContentSize:CGSizeMake(320, 650 + 100)];

	CGRect r;
	r.origin.x    = 0;
	r.origin.y    = 0;
	r.size.width  = 320;
	r.size.height = 650;
	imageView = [[UIImageView alloc] initWithFrame:r];
	imageView.image = [UIImage imageNamed:@"apple.jpg"];

	r.origin.y    = 650;
	r.size.height = 100;
	textView = [[UITextView alloc] initWithFrame:r];
	textView.backgroundColor = [UIColor blueColor];
	textView.text = @"Hello, world";
	[contentView addSubview:imageView];
	[contentView addSubview:textView];

	self.view = contentView;
	[contentView release];

- (void)dealloc {
	[imageView removeFromSuperview];
	[textView  removeFromSuperview];
	self.imageView = nil;
	self.textView  = nil;
        [super dealloc];


Hope this helps
