Last night I was doing an application using Flash Builder 4.6. I was stuck in a point about transitions in an iOS application.
I could have used an Add-Delete View plan but instead I tried something else.
Instead I could have used Add-Delete View plan; I tried another:
navigator.pushView(YourViewNameWithoutExtension);

Assume we have 2 mxml pages in our application. "iMediaHomeView" and "Facebook" for example.

FaceBook.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
actionBarVisible="true" color="#FF0000" overlayControls="false" tabBarVisible="true"
title="Facebook">

<fx:Script>
<![CDATA[

function GetBack()
{
navigator.pushView(iMediaHomeView);
}

]]>
</fx:Script>

<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Button x="25" y="734" label="All Sites" color="#000000"/>
 <s:Button x="515" y="735" label="Exit" color="#030303"/>
 <s:Button x="289" y="734" label="Back" color="#000000" click="GetBack();"/>
</s:View>


iMediaHomeView.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
actionBarVisible="true" color="#FF0000" overlayControls="false" tabBarVisible="true"
title="iMedia">

<fx:Script>
<![CDATA[

function Show_Facebook()
{
navigator.pushView(Facebook);
}

]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Image x="177" y="24" width="128" height="128" scaleMode="stretch" smooth="true"
 smoothingQuality="high" source="assets/facebook.png" click="Show_Facebook_();"/>
 <s:Button x="515" y="735" label="Exit" color="#030303"/>
</s:View>

Let me show you the output images:

As Default iMediaHomeView.mxml file is being displayed according to my application.

After we click on Facebook icon it links to my FaceBook view object.

When I click on the Back button it again shows my homepage "iMediaHomeView".

That way I found a way to wander between views.

Hope it will be useful for you, too.
