I would be highly surprised if using that method would not be considered use of private API. The two public init methods are useful when you want to create pages yourself. When opening a PDF document you’ll have to resort to other options to perform custom setup of pages. Is there a particular reason that you really need to be active during the init process? I find that I can do whatever I need by iterating through a document’s pages shortly after loading the document. You could declare a method on your subclass, say “finishSetup”, and then call that on each page as you iterate throughout the pages once you have obtained the document from initWithURL:.
