How to make this app screen scroll?

I've a screen in an app I'm coding structured like this:

View
    ScrollView
        View
            label 1
            label 2
            label 3
        View
            UIImageView
        WebView

When loaded it adds some html string into the Web View and as the whole content (labels,image,html content) is longer than the screen height, I would like to allow the screen to scroll down/up when user is reading content. This is why I added the SrollView but nothing scroll!

I also did is scroll_view.contentSize = [self.view bounds].size; but it didn't work

Any idea on how to do this ?

Thx in advance for helping,

Stephane

Below code u observe Here "Height" declare Dynamically as your Requirement 

EXample :
if([Myarray  length]>25)
{

myString = [myString stringByAppendingFormat:@"<tr><th align=\"left\">%@</tr>",str_owes ];
height += 50;
}

  webview.frame=CGRectMake(25, 153, 420, height);
 [webview loadHTMLString:myString baseURL:nil]; 

scrollview.contentSize=CGSizeMake(0, webview.frame.origin.y+webview.frame.size.height+50);

By default UIScrollView is set a contentSize equal to its frame size. If you want it to be scrollable, you have to explicitly set the contentSize.

scrollView.contentSize = CGSizeMake(_width, _height);

Mostly you won't be knowing the actual contents size while you create the scroll view. You can assign the contentSize after adding the UIWebview(as web view is the last view in your scroll view). You can do it like this,

// Add other views to scrollView
// Create and configure webView
[scrollView addSubview:webView];

float _width = scrollView.contentSize.width; // No change in width
float _height = CGRectGetMaxY(webView); // Returns (webView.frame.origin.y + webView.frame.size.height)
scrollView.contentSize = CGSizeMake(_width, _height);

You need to set the UIScrollView's contentSize to be the size of the two views + the UIWebView combined.

You will also need to make sure that the UIWebView if of the right size and then turn scrolling off, as you may get scrolling issues otherwise (one scroll view inside another).
