It's simpler than you think, for example you have an UITextView called "textDesc" inside your UIScrollView, and you want to know the size of content, so next step will looks like that:

int contentHeight = textDesc.frame.size.height + textDesc.frame.origin.y;

After calculating the size of textDesc, just set it:

[scrollView setContentSize:(CGSizeMake(320, contentHeight))];

That's all, now your scrollView know the size of your text inside him, and will resize automatically, hope this helps, good luck.
