iOS: Add subview with a fix position on screen

Question

How do I fix a subviews position on screen (especially in UIScrollView and UITableView)? I think in storyboard

[self.view addSubview:aSubView];

Answer 1

If its a simple view controller which contains a table view, [self.view addSubview:aSubView] should work. But if its a table view controller, it wont work.
