SWF loading not working on AIR for iOS

Hey. Code running on Android, the iPhone does not work on. I want to do is this: there is a SWF file in a folder located in documentsDirectory. This is the file I want to load it into a MovieClip. The code I wrote below. Do you think what is the problem? Thank you for your help in advance.

import flash.display.StageAlign;

import flash.display.StageScaleMode;

import flash.events.ErrorEvent;

import flash.events.Event;

import flash.events.LocationChangeEvent;

import flash.events.StageOrientationEvent;

import flash.filesystem.FileStream;

import flash.events.TransformGestureEvent;

var pf:Object;

var loaderSWF:Loader = new Loader();

var fileSWF:File = File.documentsDirectory.resolvePath("dergievi/1/dergi.swf");

loaderSWF.load(new URLRequest(fileSWF.url));

loaderSWF.contentLoaderInfo.addEventListener(Event.COMPLETE, setPosition);

function setPosition(e:Event):void{

          var contPF = new MovieClip();

          contPF.addChild(loaderSWF.content);

          ana_dergi.addChild(contPF);

          pf=loaderSWF.content;

          pf.width=640;

          pf.height=880;

}
