load local html on iOS, width event handling

May 27, 2013 6:45 AM

Tags: #air #as3 #ios #ipad

Hi,

I need to donwload/update and load presentations on iPad. Working with external .swf resulted with uncontrolled crash of application. Im looking for rescue in HTML & JS build presentation.

I'm trying to find solution, that allow me to load .html file from applicationStorageDirectory, and capture events, like window.status in HTMLHost & HTMLLoader, but:

- HTMLloader is not supported on iOS (code that works for desktop, doesn't work for iOS distribution)

- WebStageView doesn't allow me to interact with app, only historyBack()/historyForward()

 

Does anybody try with success to load and interact html in AIR on iOS, and can shere the solution with others?

its not so easy. you can use webstageview. to call javscript from actionscript you have to do something like that  this.webview.loadURL("javascript:myfunction('value'));"); notice that you have to call functions.

 

if you want to call as3 function from javascript you have to use somthing like that    window.location.href = "myprotocoll:myfunction?parameter=test";

and in AS3 you need to catach this redirect:

this.webview.addEventListener(LocationChangeEvent.LOCATION_CHANGING,lo cationChanging);

 

public function locationChanging(evt:LocationChangeEvent):void

{

var currLocation : String = unescape( (evt as LocationChangeEvent).location );

 

switch( true )

{

// javascript calls actionscript

case currLocation.indexOf( 'myprotocoll') != -1:

 

parseCallBack( currLocation.split('myprotocoll' )[1] );

break;

}

 

evt.preventDefault();

}

 

this is small example I haven't testet it. I use my own JS-AS-Bridge to transfer images or paths, objects, usinge base64 encoding. You can also usehttp://code.google.com/p/stagewebviewbridge/
