This module wraps PDF iOS Core to give Titanium developers more options for displaying PDF files. PDF iOS Core is a fully featured reader, most options are included with this module. Source is provided, but also distributions inside the dist folder to get started quickly.

Use the module like this:
// open a single window
var win = Ti.UI.createWindow({
backgroundColor : 'white'
});
var label = Ti.UI.createLabel();
win.add(label);
win.open();
// Include PDFReader
var PDFReader = require('com.josiah.pdfreader');
Ti.API.info("module is => " + PDFReader);
label.text = 'Click to open PDF viewer';
label.addEventListener('click', function(e) {
// Resolve the file path and open PDF
var f = Ti.Filesystem.getFile('Reader.pdf');
PDFReader.openPDFViewer(f.resolve());
});
PDFReader.addEventListener('close', function() {
// Catch the close event
Ti.API.info('closed');
});
