scrolling not working for views inside tabbar application

Question

I have created a tabBar application, it has two tabs one tableView with detail items and another simple UIView with a UILabel . I added scrollView to detailViewController and put all UI items under scrollView to get scrolling. I connected the scrollView using outlet to my detail view and set the following in detailViewController

[scrollView setScrollEnabled:YES];
    scrollView.contentSize = CGSizeMake(scrollView.frame.size.width,scrollView.frame.size.height);

However detail view is not scrolling, its screen is locked. why?

Answer 1

For a UIScrollView, you want the frame to be the size you want it to appear on the screen, and the content size to be the size it will be able to scroll through. So, for scrolling to work properly, you must have the content size set to larger than the view's size in one dimension or the other.
