Does PDFView refer to a view containing the enclosing scroll
view, or perhaps the scroll view itself? If so, why does -[PDFView
drawPage:] exist?
One use is that it can be overridden for all kinds of customization.
For instance, you may need to draw a selection rectangle during a drag
on a page. You could do that in PDFView's drawPage: method.
- (void)drawPage:(PDFPage *)page
{
// Draw the source PDFPage
[super drawPage:page];
// Draw whatever you want to appear on top of the page. E.g:
if (self.masterDocument.onScreenDisplayBoxes > 0) {
[self drawOnscreenDisplayBoxesForPage:page];
}
if (page == mouseDownPage) {
[self drawDraggingFeedbackOnPage:page];
}
}
