LoaderMax on Air for iOS problem

Recommended Posts

Hi, I am having a problem with LoaderMax on Air for iOS. My solution works fine on air for android, but apple doesn't allow you to store downloaded files in the application folder, it has to go into ../Library/Caches instead.


i am downloading to this from the net to



savePath= new File(File.applicationDirectory.nativePath +"/\.\./Library/Caches/" + filename);


fileStream.open(savePath, FileMode.WRITE);

urlStream.load(new URLRequest(url));




urlStream.readBytes(fileData, 0, urlStream.bytesAvailable);



which works fine.


when i try to load the downloaded files with loadermax it bombs.




it works very well on android but i cant get LoaderMax fo find the files on iOS.

i get the following error when debugging on OSX:


i add a number of files with:

			   			   var queue:LoaderMax = new LoaderMax({name:"soundQueue", onComplete:loopSoundsCompleteHandler, onError:errorHandler});
					 						 fileName =  "Library/Caches/" + fileName;
									queue.append( new MP3Loader(fileName, {name:"name1", repeat:-1, autoPlay:false}) );

and then i load the queue with



and i reveice the following error:


Error on MP3Loader 'bpallah' (Library/Caches/resources/snd/bpall.mp3): Error #2032: Stream Error. URL: app:/Library/Caches/resources/snd/bpall.mp3


Does anyone have a clue how to do this?

That error means that the file isn't at that URL that you provided. Frankly I'm not familiar with the ins and outs of AIR apps on iOS or where you need to store/retrieve files, etc. If someone else can chime in here, that'd be great. But suffice it to say that the problem is definitely that the file isn't where you're telling LoaderMax to look, so maybe try some different URLs (relative paths, etc.)

Make sure you use the "url" property of File when you need to generate a URL you can load.

I have been digging a bit more into this problem.


if i use the following code:



var str:String = File.applicationDirectory.nativePath;


_pointModel.mainImage= LoaderMax.getContent(str+"/\.\./Library/Caches/resources/img/4/4_mamma.jpg");


var file:File = new File(str +"/\.\./Library/Caches/resources/img/4/4_mamma.jpg");


if(file.exists) {




the traces will show:







So the file seems to be in the right place, but the LoaderMax.getContent() method returns null.


if I try to load it explicitly with ImageLoader



var loader:ImageLoader = new ImageLoader(str +"/\.\./Library/Caches/resources/img/4/4_mamma.jpg", {name:"photo1", container:_pointModel.mainImage,scaleMode:"proportionalInside", centerRegistration:true, onComplete:onImageLoad, onError:onErrorCode});



I get the following error:



error:ImageLoader 'photo1' (/Users/larshansson/Documents/src/ParkenMobile/bin-debug/../Library/Caches/resources/img/4/4_mamma.jpg) > Error #2035: URL Not Found. URL: app:/Users/larshansson/Documents/src/ParkenMobile/Library/Caches/resources/img/4/4_mamma.jpg


if I change the path above to:


var loader:ImageLoader = new ImageLoader("app:/\.\./Library/Caches/resources/img/4/4_mamma.jpg", {name:"photo1", container:_pointModel.mainImage,scaleMode:"proportionalInside", centerRegistration:true, onComplete:onImageLoad, onError:onErrorCode});


i get



*** Sandbox error ***

Access tp app:/../Library/Caches/resources/img/4/4_mamma.jpg has been stopped - not allowed from app:/ParkenMobile.swf

Two questions:


1) What data type is your _pointModel.mainImage property?


2) What happens if you run this after the load?:

1) it is a ContentDisplay


2) null


i am loading the data with this code from an external xml document:


var xmlFileName:String = "/resources/txt/punkt4.xml";

LoaderMax.activate([VideoLoader, ImageLoader, SWFLoader, DataLoader, MP3Loader]);

loader1= new XMLLoader(xmlFileName, {name:"xmlDoc",skipFailed:true, noCache:true, onComplete:handleXMLLoaded, onError:handleError});



the file punkt4.xm l is allowed to be placed under app-storage as i compile it into to the swf.


the punkt4.xml file looks like this:


<?xml version="1.0" encoding="UTF-8"?>



<LoaderMax name="dynamicLoaderMax" load="true">

<ImageLoader name="4_mamma" url="app-storage:/resources/img/4/4_mamma.jpg" load="true"/>

<ImageLoader name="4_mhandtag" url="app-storage:/resources/img/4/cutout/4_mhandtag.jpg" load="true"/>

<ImageLoader name="4_mjorden" url="app-storage:/resources/img/4/cutout/4_mjorden.jpg" load="true"/>

<ImageLoader name="4_mdocka" url="app-storage:/resources/img/4/cutout/4_mdocka.jpg" load="true"/>

<ImageLoader name="4_mbrev" url="app-storage:/resources/img/4/cutout/4_mbrev.jpg" load="true"/>

<MP3Loader name="bs2" url="app-storage:/resources/snd/bs2.mp3" load="true" autoPlay="false" repeat="1"/>




it works like charm on all other platforms, but then again on those platforms i can place the files were they are supposed to be. Not were apple forces me to put them.


I am getting to a point were i might just compile all the data into the .swf and be done with it.

Yeah, I'm not quite sure what to suggest here, especially since I'm not experienced with iOS and the idiosyncrasies of where it requires files, which actions trip security problems, etc. Your inclination to put things into an .swf file sounds pretty solid at this point.
