Small sample that demonstrates page scrolling controlled by a slider that snaps to values along the length. For Titanium works on Android and iOS. You can do whatever you want with this code.

SliderPageScrollSample.js

var win = Ti.UI.createWindow({
  fullscreen: true,
	backgroundColor: 'gray',
	layout: 'vertical'
});

//This function is used to create our pages
function newPage(pageColor, leftPos){
	v = Ti.UI.createView({backgroundColor: pageColor, left: leftPos, height: Ti.Platform.displayCaps.platformHeight * 0.9, width: Ti.Platform.displayCaps.platformWidth});
	return v;
};

//create the pages
var page1; var page2; var page3; var page4; var page5; var page6; var page7; var page8;
//Add pages to an array so they can be added 
var pageArr = [page1, page2, page3, page4, page5, page6, page7, page8];
//Add the page colors to the array
var styleArr = ['red', 'blue', 'white', 'green', 'purple', 'yellow', 'blue', 'red'];


//Set the number of pages you wish to use
var numberOfPages = pageArr.length;

//Create a container view that can hold all of our pages
var view = Ti.UI.createView({
	backgroundColor: 'black',
	left: 0,
	height: Ti.Platform.displayCaps.platformHeight * 0.9,
	width: Ti.Platform.displayCaps.platformWidth * numberOfPages
});
win.add(view);

//Create pages and add them to the main view
for(var i = 0; i < pageArr.length; i++){
	var leftPos = Ti.Platform.displayCaps.platformWidth * i;
	pageArr[i] = newPage(styleArr[i], leftPos);
	view.add(pageArr[i]);
};

//Create the slider and set the width
var snapSlider = Ti.UI.createSlider({
	min: 0,
	max: numberOfPages - 1,
	width: '80%',
	center: 0,
	value: 0,
	bottom: Ti.Platform.displayCaps.platformHeight / 10
});
win.add(snapSlider);

snapSlider.addEventListener('touchend', function(e){
    this.value = Math.round(e.source.value);//This allows the slider to snap to set points
 	//We then animate the view to display the correct page
	view.animate({left: -Ti.Platform.displayCaps.platformWidth * this.value, duration: 1000});

});

win.open();
