iphone - Calculate the contentsize of scrollview

I'm having a scrollview as the detailedview of tableview cell. There are multiple views on the detailedview like labels, buttons etc. which I'm creating through interface builder. What I'm creating through interface builder is static. I'm putting everything on a view of height 480.

A label on my detailedview is having dynamic text which can extend to any length. The problem is that I need to set the scrollview's content size for which I need its height.

How shall I set scrollview's height provided the content is dynamic?

You could try to use the scrollview'ers ContentSize. It worked for me and I had the same problem with the control using dynamic content.

    // Calculate scroll view size
float sizeOfContent = 0;
int i;
for (i = 0; i < [myScrollView.subviews count]; i++) {
    UIView *view =[myScrollView.subviews objectAtIndex:i];
    sizeOfContent += view.frame.size.height;
}

// Set content size for scroll view
myScrollView.contentSize = CGSizeMake(myScrollView.frame.size.width, sizeOfContent);

I do this in the method called viewWillAppear in the controller for the view that holds the scrollview. It is the last thing i do before calling the viewDidLoad on the super.

Hope it will solve your problem.
