iOS - PDF Loaded in UIWebView then save to iBooks using UIDocumentInteractionController
问题 I am loading a PDF from the web using a UIWebView, which works great and lets me interact with the PDF how I want. Next I would like to be able to save that PDF to iBooks, so I am using a UIDocumentInteractionController. In reading the docs it seems that you can only use UIDocumentInteractionController with local files rather than a remote file like I have. My question is, that PDF that UIWebView loads must be cached somewhere, so I really have to do another call to download that same file,
