Unable To Build iOS App Using Native Extension

Question

I’m trying to create a native extension for iOS and use that extension as part of an IPA app for iOS I create from a SWF file using the ADT tool (i.e. the normal use-case for iOS). Note: I have already successfully created the native extension and APK app for Android and now I am trying to build the iOS side.
I have been primarily using the information found at the following websites:
http://www.adobe.com/devnet/air/articles/building-ane-ios-android-pt3.html
http://www.adobe.com/devnet/air/articles/building-ane-ios-android-pt5.html
http://help.adobe.com/en_US/air/build/WS901d38e593cd1bac35eb7b4e12cddc5fbbb-8000.html
I have also searched the Adobe forums for the answer to my question without success.
The error I receive is:
ld: warning: ignoring file /var/folders/c3/mpg4frwn2j1f8scw4jctbmv9hfkswj/T/bd3fbd4a-cf56-4fd6-a06d-d69ea92dc620/lib com.mycompany.MyExtension.a, file was built for archive which is not the architecture being linked (armv7): /var/folders/c3/mpg4frwn2j1f8scw4jctbmv9hfkswj/T/bd3fbd4a-cf56-4fd6-a06d-d69ea92dc620/lib com.mycompany.MyExtension.a

Compilation failed while executing : ld64
I receive the above error when I execute the following command:
adt -package -target ipa-ad-hoc -storetype pkcs12 -keystore certificate.pfx -provisioning-profile provisioning_profile.mobileprovision MyApp.ipa MyApp.xml MyApp.swf -extdir packaged-extensions
where the folder “packaged-extensions” contains the ANE file I created using this command:
adt -package -target ane packaged-extensions/MyExtension.ane MyExtension.xml -swc MyExtension.swc -platform Android-ARM -platformoptions platformAndroidARM.xml -C dependencies . -C platform/Android . -platform iPhone-ARM -platformoptions platformiOSARM.xml -C platform/IOS . -platform default -C platform/default library.swf
where the content of the files are as follows:
MyApp.xml:
<application xmlns="http://ns.adobe.com/air/application/4.0">
    <id>MyApp</id>

  <linkerOptions>
    <option>-ios_version_min 5.1</option>
    <option>-liconv</option>
  </linkerOptions>
</platform>
MyExtensionIOSLibrary.m (yes, I know it doesn't do anything - it's simple on purpose to help isolate the error):
#import "FlashRuntimeExtensions.h"
void MyContextInitializer(void* extData, const uint8_t *ctxType, FREContext ctx, uint32_t *numFunctionsToTest, const FRENamedFunction **functionsToSet) {
  return;   
void MyExtensionInitializer(void **extDataToSet, FREContextInitializer* ctxInitializerToSet, FREContextFinalizer* ctxFinalizerToSet) {
    *extDataToSet = NULL;
    *ctxInitializerToSet = &MyContextInitializer;
void MyExtensionFinalizer(void *extData)
    return;
I am using XCode to build MyExtensionIOSLibrary.m into a library file with a .a filename extension. My relevant build settings are:
iOS Deployment Target: iOS 5.1
Architectures: armv7
Build Active Architectures Only: No
Product Scheme: Release
Compile Sources As: Objective-C
Any ideas? Please help.

Thanks for the reply.
yes.I've created a static library with 3rd party frameworks and pulled the .a from product folder(Debug-iphoneos).
and the framework didn't work(armv7 not supported error occurs ..don't know why) with it's original folder structure .
so I followed below link to change folders inside the 3rd party framework and figured out but now  the application crashes on startup without giving an error message. .
