AS3 iOS Twitter Reader not working

Report · Feb 08, 2012

I created a Twitter Feed reader using a tut from fladev.com. By itself, it works GREAT! However when I try to incoroporate it into my fla for compiling into my ipa it doesn't work in my swf. I know that if I compile the twitter reader at runtime with my main fla that it won't work in my ipa because my swf has a class as running in it. But when I try putting my twitter reader directly into my main fla I get nothing! My scene loads but it pulls down no data. Here is my class code that I am using:

package fladev.twitter

{

import flash.display.Loader;

import flash.display.Sprite;

import flash.display.MovieClip

import flash.events.Event;

import flash.events.SecurityErrorEvent;

import flash.net.URLLoader;

import flash.net.URLRequest;

import flash.text.TextField;

import flash.events.MouseEvent;

public class MainClass extends Sprite

{

public var content_txt:TextField;

public var posted_txt:TextField;

public var info_txt:TextField;

public var name_txt:TextField;

public var btnhome:MouseEvent;

private static const USERNAME:String = "mytwitterid";

private static const URL:String = "http://pathtomyphp.com/proxy.php";

private static const REQUEST:String = URL + USERNAME;

private var urlLoader:URLLoader;

private var xml:XML;

private var loader:Loader;

private var num:Number = 5;

public function MainClass() {

urlLoader = new URLLoader();

urlLoader.load(new URLRequest(REQUEST));

urlLoader.addEventListener(Event.COMPLETE, displayInfo);

urlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurity);

}

private function onSecurity(e:SecurityErrorEvent):void

{

}

private function displayInfo(e:Event):void

{

xml = new XML(e.target.data);

content_txt.htmlText = getContent(0) + getContent(1) + getContent(2)+ getContent(3);

info_txt.text = "Followers: " + xml.status[num].user.followers_count + "; " + "Following " + xml.status[num].user.friends_count + "; " + "Tweets " + xml.status[num].user.statuses_count + ";";

name_txt.text = xml.status[num].user.screen_name;

loader = new Loader();

loader.load(new URLRequest(xml.status[num].user.profile_image_url));

addChildAt(loader, 1);

loader.x = 116;

loader.y = 102;

}

private function getContent(num:Number) {

var posted:String = xml.status[num].created_at;

var content:String = "<a href=" + '"http://twitter.com/' + USERNAME + "/statuses/" + xml.status[num].id + '" target="_blank">' + xml.status[num].text + "</a> " +"Posted on: " + posted.substr(0, posted.length - 11) + "; " + "From: " + xml.status[num].source + " ";

return content;

}

Like I said, on its own, it works great, just not when I try to create a new scene in an existing fla.

Thanks in advance for any advice you can give me. I'm a little bit of an as3 newbie, so please bare with me . . .

is MainClass your document class?

Report · Feb 09, 2012

Yessir . . . when I remove it as my document class and try to import it on the timeline using this:

//--------------------------

import fladev.twitter.MainClass;

var twitterReader:MainClass = new MainClass();

//--------------------------

I still get a no twitter info and I get this in my output:

//--------------------------

TypeError: Error #1085: The element type "link" must be terminated by the matching end-tag "</link>".

at flash.net::URLLoader/onComplete()

//--------------------------

Not sure if this helps or adds to the confusion.

when you use MainClass as your document class does it work the way you expect?

if yes, and you're trying to change it to a non-document class, you need to use a stage reference to access those textfields and you need to add twitterReader to the stage asap. but that would be a different error than the one you're seeing.

private function displayInfo(e:Event):void

{

var _root:MovieClip = MovieClip(this.root); // assuming you add this class instance to the main timeline before loading is complete.

xml = new XML(e.target.data);

_root.content_txt.htmlText = getContent(1) + getContent(2)+ getContent(3) + getContent(4);

//trace(xml);

//show some info about the user

_root.info_txt.text = "Followers: " + xml.status[num].user.followers_count + "; " + "Following " + xml.status[num].user.friends_count + "; " + "Tweets " + xml.status[num].user.statuses_count + ";";

//display the user account

_root.name_txt.text = xml.status[num].user.screen_name;

//create a loader for picture

loader = new Loader();

loader.load(new URLRequest(xml.status[num].user.profile_image_url));

_root.addChildAt(loader, 1);

loader.x = 116;

loader.y = 102;

}

Okay, so I made the changes you suggested and now I get a bunch of "1180: Call to a possibly undefined method gotoAndStop" errors, which completely baffles me. My swf won't generate because of these errors so I don't know how the changes have effected my fla.

So I decided to try to put my twitterReader in a MovieClip. MainClass is no longer my document class and is now linked instead to my twitterReader MovieClip extending it to a Sprite and I now get the same error as before with this:

TypeError: Error #1085: The element type "link" must be terminated by the matching end-tag "</link>".

if you were using MainClass as your document class, there should have been no problems. were there?

Report · Feb 09, 2012

Yeah, I was getting that "1180: Call to a possibly undefined method gotoAndStop" error.

start over. download the files from your tutorial. any problem if you use the files from the tutorial?

Report · Feb 09, 2012

Nope, no problems at all. I can get it to pull my twitter feeds and everything. Problems begin occurring when I try to use it in another project, whether it be on a different frame on the timeline, a different scene etc. I can load the twitreader swf in my project with no problems as well. But because I am trying to use this in an iOS app I'm building I can't load it because ti has script to it so it has to be contained in the main as best as I can tell.

Report · Feb 09, 2012

ok, now start with the sample fla from that website,

1. remove the document class,

2. change the code in MainClass to the class i showed and

3. add a MainClass instance to the fla's main timeline using:

var mc:MainClass=new MainClass();

addChild(mc);

4. test.

Report · Feb 09, 2012

Alright, so I re-downloaded the sample files, I changed this part MainClass code:

private function displayInfo(e:Event):void

{

var _root:MovieClip = MovieClip(this.root);

xml = new XML(e.target.data);

_root.content_txt.htmlText = getContent(1) + getContent(2)+ getContent(3) + getContent(4);

//trace(xml);

//show some info about the user

_root.info_txt.text = "Followers: " + xml.status[num].user.followers_count + "; " + "Following " + xml.status[num].user.friends_count + "; " + "Tweets " + xml.status[num].user.statuses_count + ";";

//display the user account

_root.name_txt.text = xml.status[num].user.screen_name;

//create a loader for picture

loader = new Loader();

loader.load(new URLRequest(xml.status[num].user.profile_image_url));

_root.addChildAt(loader, 1);

loader.x = 116;

loader.y = 102;

}

I removed MainClass as the document class. and added this:

var mc:MainClass=new MainClass();

addChild(mc);

on the main timeline.

When I test this is what pops up in my Compiler Errors:

Scene 1, Layer 'Actions', Frame 1, Line 1	1180: Call to a possibly undefined method MainClass.
Scene 1, Layer 'Actions', Frame 1, Line 1	1046: Type was not found or was not a compile-time constant: MainClass.

put MainClass in the same directory with your fla, swf, html

Report · Feb 10, 2012

I put MainClass in the same folder as the fla (it was in a subfolder in the same directory) and I still get the 1180 and 1046 errors. Just to confirm, I have this in the first frame of the timeline:

var mc:MainClass=new MainClass();

addChild(mc);

HOLY FREAKIN' AWESOME! Yes! It now works in my other fla as well! Thank You! Thank You! Thank You! So, kglad, what was it that I was doing wrong? I can't help but to be a little perplexed at the turn of events.

i'm not sure. i think your fla might have had some setting that wasn't allowing it to see the MainClass file in the same directory as the flash files.

i am sure the fla from that website had some setting that caused a problem with paths. i didn't realize it until i made those files this morning. i couldn't determine the problematic setting so i created a new fla (with standard publish settings) and copied the frames from that website's fla to the new fla at which point everything worked, as expected.

p.s. please mark helpful/correct responses.
