How to make current view a scrollview? iOS / Objective C

Question

I have a view (that is actually part of a UINavigationControllers view) that i want to make a scrollview.

how do i do that?

could i do something like this:

UIScrollView * content = [[UIScrollView alloc] initWithFrame:self.view.bounds];
self.view = content

(obviously that doesn't work, but is there a way to do it like that)?

Answer 1

Yes, it is, you have to implement delegates, and set the contentSize. The best tutorial on scrollViews ever I found is:

You are on a good way!

Answer 2

You can create the scroll view programmatically like you do and then add the existing view as a subview of this new scroll view, examine addSubview: (which works on all UIView s and subclasses like UIScrollView as well). I won't say this is the solution or even a clean one for that matter, but if you read about addSubview: you can at least figure out how to have a view live inside a scroll view...
