How to enable iTunes FileSharing on AIR for iOS Devices

admin — Sat, 07 May 2011 09:18:04 +0000

I was searching the net to find a way to enable FileSharing with itunes on my AIR for IOS app.

After some research, this is the simple way it can be done:

Edit your application descriptor xml file
In the InfoAdditions section add the next two lines of code
Recompile you project and update the app via iTunes
After sync with iTunes, your app now can share files within the app Documents directory

1 2	<key>UIFileSharingEnabledkey> <true/>

dropbox-as3. Creating new accounts

admin — Thu, 07 Apr 2011 11:32:42 +0000

I have made some changes in the fantastic dropbox-as3 library that allow us to create new dropbox accounts.

// create dropbox instance
var config:DropboxConfig = new DropboxConfig( "ConsumerKey","ConsumerSecret");
var dropAPI:DropboxClient = new DropboxClient(config);

// assign createAccount events
dropAPI.addEventListener(DropboxEvent.ACCOUNT_CREATE_RESULT, onCreationResult );
dropAPI.addEventListener(DropboxEvent.ACCOUNT_CREATE_FAULT, onCreationFault );

// call createAccount and pass ( email, password --> min 8 chars, first name, last name )
dropAPI.createAccount('email@example.com','12345678','first_name','last_name');

// Event fired on success
public function onCreationResult( e:DropboxEvent ):void
{
trace( 'ACCOUNT_CREATE_RESULT '+e.resultObject.status );
}

// Event fired on error
public function onCreationFault( e:DropboxEvent ):void
{
trace( 'ACCOUNT_CREATE_FAULT '+(e.resultObject as AccountCreationError).toString() );
}

StageWebViewBridge. Updated. Automatic cache creation.

admin — Wed, 06 Apr 2011 01:42:30 +0000

StageWebViewBridge class was upgraded with new features for managing files in the cache.

With the new system it is possible to forget if a cached file is updated, the system does everything for us and finally we get 2 output directories. These 2 directories are the directories we must include in our final package release.

The new methods and properties:

1 2	// sets Debug mode on/off StageWebViewBridge.DEBUGMODE = true/false;

1
2
3
4
5
6

// sets the default dir to 'htmlFiles'
StageWebViewBridge.setRootFolder('htmlFiles');

// this will create 2 new dirs
app:/htmlFilesCache
app:/htmlFilesSource

1
2
3
4
5

// Change the extensions of the files to parse.
// Default extensions are ["html","htm","css","js"]

// now limit the files to be html or js, and left intact the css and htm files
StageWebViewBridge.setSourceFileExtensions(['html','js']);

StageWebView StageWebViewBridge Communicating between actionscript and javascript and vice versa

admin — Sat, 26 Mar 2011 19:56:49 +0000

I have made an extended StageWebView Class that lets you:

* Communicate Actionscript with Javascript.
* Communicate Javascript with Actionscript.
* Load local files and resources in a easy way.
* Extend loadString method with AS3 – JS communication.

By example you can call javascript from as3

1 2	// call javascript with callack function webView.bridge.call('someFunctionToCall', callBackFunction, ...arguments );

// reference local resources in a easy way

OSX 5005:Unknown error optimizing byte code

admin — Tue, 31 Aug 2010 12:29:55 +0000

Working in a large AIR project, the flash compiler give me this strange error:

1	5005:Unknown error optimizing byte code

To avoid it , we must increase the memory of the compilator by creating a file in:

1	~/.MacOSX/environment.plist

and put this text in it:

1
2
3
4
5
6
7
8

JAVA_TOOL_OPTIONS
-Xmx512m

If you use flash CS5 also edit this file:

1	~/Library/Application Support/Adobe/Flash CS5/en_US/Configuration/ActionScript3.0/jvm.ini

Then change -Xmx128m to -Xmx512m

AS3 Condicional Switch Stament

admin — Wed, 28 Apr 2010 15:55:37 +0000

Imagine we can use switch staments with conditional operators other then strict equality.

This way we can do a code like this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18

var value:int = 2;
switch(value){
case < 1:
trace("Value is less than 1");
break;
case 2:
trace("Value definitely equals 2");
break;
case >= 3:
trace("Value is greater than or equal to 3");
break;
case > 1 && < 3:
trace("Value is greater than 3 and less than 5");
break;
case !== 5:
trace("Value definitely doesn't equal 5");
break;
}

Navigating the web I have find one solution:

1
2
3

12

var value:int = 2;
switch (true) {
case value < 1:
trace("Value is less than 1");
break;
case value == 1:
trace("Value equals 1");
break;
case value > 1:
trace("Value is greater than 1");
break;
}

Dynamically create instance of Vector class

admin — Thu, 08 Apr 2010 14:39:12 +0000

AS3 don’t let us dynamically create an instance of class Vector with elements of various types, the solution is use getDefinitionByName.

package
{
import flash.system.ApplicationDomain;
import flash.utils.getQualifiedClassName;

public class ClassUtils
{
static private const VECTOR_CLASS_NAME : String = getQualifiedClassName( Vector );

static public function getVectorDefinition(itemDefinition : Class, applicationDomain : ApplicationDomain = null) : Class
{
if(!applicationDomain) applicationDomain = ApplicationDomain.currentDomain;
return applicationDomain.getDefinition( VECTOR_CLASS_NAME + '.<' + getQualifiedClassName( itemDefinition ) + '>' ) as Class;
}
static public function createCustomVector(itemDefinition : Class, length : uint = 0, fixed : Boolean = false, applicationDomain : ApplicationDomain = null) : Vector.<*>
{
var definition : Class = getVectorDefinition( itemDefinition, applicationDomain );
return new definition( length, fixed );
}
}
}

To get definition of Vector class with specified item type:

1

4

var itemType:Class = Sprite;
var definition:Class = ClassUtils.getVectorDefinition(itemType);
trace(definition); // [class Vector.]
trace(getQualifiedClassName(definition)); // __AS3__.vec::Vector.

To create Vector class instance with specified item type:

1

3

var itemType:Class = Sprite;
var vector:Vector.<*> = ClassUtils.createCustomVector(itemType);
trace(getQualifiedClassName(vector)); // __AS3__.vec::Vector.
