iOS UIScrollView work as UIWebView

[pashik]

Is it possible to make UIScrollView to work as UIWebView, that is:
user can scroll to some place and zoom it out/in but rectangle of UIScrollView won't be zoomed out - just view inside UIScrollView will be zoomed out.
E.g. in this code

	sview = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0,320, 460)];
	sview.autoresizesSubviews = YES;
	sview.delegate = self;
	sview.userInteractionEnabled = YES;
	sview.minimumZoomScale = 0.25;
	sview.maximumZoomScale = 2;
	sview.scrollEnabled  =YES;
	sview.bounces = YES;
	sview.bouncesZoom = YES;
	sview.contentSize = CGSizeMake(3200, 4600);
	sview.scrollsToTop = NO;
	sview.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
	
	UIView *block = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 3200, 4600)]; 
	block.backgroundColor = [UIColor blueColor];
	//add some elements to view
	
	[sview addSubview:block];

...
-(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView{
return sview;
}

I set background color of view inside UIScrollView to blue.
When i make zoomout - i can see only that rectangle 320x240 is zoomed out (so blue square become small) but the rest part of view is not visible though i can scroll it (scroll inside blue view) without problem.
So how to make so that i can see blue view and it will be zoomed out in whole screen and not in rectagle 320x240?
