Overview

A PDFView object encapsulates the functionality of PDF Kit into a single widget that you can add to your application using Interface Builder.

PDFView may be the only class you need to deal with for adding PDF functionality to your application. It lets you display PDF data and allows users to select content, navigate through a document, set zoom level, and copy textual content to the Pasteboard. PDFView also keeps track of page history.

You can subclass PDFView to create a custom PDF viewer.

You can also create a custom PDF viewer by using the PDF Kit utility classes directly and not using PDFView at all.

drawPage:

For use by subclasses of PDFView for custom rendering of pages.

- (void)drawPage:(PDFPage *)page

Do not invoke this method, except by invoking it on super from a subclass.

The PDFView class calls drawPage: as necessary for each visible page that requires rendering. In the PDFView class, this method erases page to white, calls [page drawInRect: pageRect withBox: [self displayBox]] , and then draws the selection, if any.

You can override this method to draw on top of a PDF page or to control how pages are drawn. In these cases, invoke this method on super and then perform custom drawing on top of the PDF page.

layoutDocumentView

Performs layout of the inner views.

- (void)layoutDocumentView
Discussion

The PDFView actually contains several subviews, such as the document view (where the PDF is actually drawn) and a “matte view” (which may appear as a gray area around the PDF content, depending on the scaling). Changes to the PDF content may require changes to these inner views, so you must call this method explicitly if you use PDF Kit utility classes to add or remove a page, rotate a page, or perform other operations affecting visible layout.

This method is called automatically from PDFView methods that affect the visible layout (such as setDocument:, setDisplayBox: or zoomIn:).

If pageScaling is set to kPDFPrintPageScaleToFit, each page is scaled up or down to best fit the paper size. If pageScaling is set to kPDFPrintPageScaleDownToFit, only large pages are scaled down to fit; small pages are not scaled up to fit. Specifying kPDFPrintPageScaleNone for pageScaling is equivalent to calling printWithInfo:autoRotate:. See PDFDocument for more information on page-scaling types.

Delegate Methods

PDFViewOpenPDF:forRemoteGoToAction:

Delegate method that opens a specified page.

- (void)PDFViewOpenPDF:(PDFView *)sender forRemoteGoToAction:(PDFActionRemoteGoTo *)action

A delegate responding to this method is called to handle clicks in an annotation that contains a PDFActionRemoteGoTo action. Such an action contains a URL, a page index, and a point. The delegate should open the PDF document specified by the URL and go to the specified page and point. An easy way to do this is to create a PDFDocument object with the specified URL and then create a PDFDestination object with the specified page and point. Then, you can call goToDestination:.
