Use this code to repro:

var win = Ti.UI.createWindow();

// Use a NavigationWindow to create a navigation bar for the window
var navWin = Ti.UI.iOS.createNavigationWindow({
	window : win
});

var navButton = Titanium.UI.createButton({
	title : 'Launch'
});
win.RightNavButton = navButton;

var docButton = Titanium.UI.createButton({
	title : 'Launch Doc',
	height : 40,
	width : 200,
	top : 180
});
win.add(docButton);

// Create a document viewer to preview a PDF file
var docViewer = Ti.UI.iOS.createDocumentViewer();
// Opens the options menu and when the user clicks on 'Quick Look'
// the document viewer launches with an animated transition
navButton.addEventListener('click', function() {
	docViewer.show({
		view : navButton,
		animated : true
	});
});
// The document viewer immediately launches without an animation
docButton.addEventListener('click', function() {
	docViewer.url = 'test1.doc';
	docViewer.show();
	setTimeout(function(){
		Ti.Media.saveToPhotoGallery(docViewer.toImage());
	}, 2500);
});

navWin.open();

Hey Eric, since I am currently working on other DocumentViewer-related tickets and found this one. I would mark it as invalid, since the doc-view is not a Ti.UI.View subclass and therefore does not have that API. It's rather a docs-issue where it states that it would have all the properties / methods that a Ti.UI.View has, but that's not the case. Anyway, we can expose this if you want - let me know!
