M13PDFKit

M13PDFKit is an iBooks like PDF viewer that can be embedded in iOS applications. M13PDFKit is based off of vfr/Reader. The backend uses the same classes that Reader uses, the front end has been recreated to match iOS 7’s design, and use more up to date features, like UICollectionViews.

Installation

Podfile

source 'https://github.com/CocoaPods/Specs.git'

pod 'M13PDFKit', '1.0.2'

Usage

Prerequisite: In the storyboard, the ViewController that is intended to display the PDF file needs to be in a UINavigationController stack and its corresponding class needs to be PDFKBasicPDFViewer

Next, in the prepareSegue method of your ViewController which segues to your PDF View Controller you will then need to add the following lines:

Objective-C

//Create the document for the viewer when the segue is performed.
PDFKBasicPDFViewer *viewer = (PDFKBasicPDFViewer *)segue.destinationViewController;

//Load the document
PDFKDocument *document = [PDFKDocument documentWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Your PDF document actual location" ofType:@"pdf"] password:nil];
[viewer loadDocument:document];

Swift

//Create the document for the viewer when the segue is performed.
var viewer: PDFKBasicPDFViewer = segue.destinationViewController as PDFKBasicPDFViewer

//Load the document (pdfUrl represents the path on the phone of the pdf document you wish to load)
var document: PDFKDocument = PDFKDocument(contentsOfFile: pdfUrl!, password: nil)
viewer.loadDocument(document)

In any case, you can see an example here in the SamplesTableViewController (Obj-C only)

Issues:

There are two issues I am unable to resolve with the framework, and would like help solving.

1. The viewer has trouble handling rotation. Upon rotation the page that is currently displayed on screen does not resize to the proper size. Once you switch pages though, everything is fine.

2. Zooming in on pages does not allow panning. Something is overrideing the content offset while panning, and not calling “setContentOffset:{0, 0}”. The pan gesture for the scroll view send the proper content offset, but the scroll view does not pan. When you pan again, the content offset starts from 0 again. It was working, but while trying to fix rotation, this broke, and I can’t figure out what is wrong.
