Crosswalk extension not working in iOS

Question

I am trying to make Crosswalk extension in iOS (Objective-C) for my own app which displays a website in Crosswalk runtime but it is not working. Following are the details:

1. Created CocoaTouch framework project at the root of my main project which is single page application.

2. Added the following code to the MyXWalkExtension.h file of my CocoaTouch framework project:

   #import <UIKit/UIKit.h>
   
   #import <XWalkView/XWalkView.h>
   
   //! Project version number for MyXWalkExtension.
   
   FOUNDATION_EXPORT double MyXWalkExtensionVersionNumber;
   
   //! Project version string for MyXWalkExtension.
   
   FOUNDATION_EXPORT const unsigned char MyXWalkExtensionVersionString[];
   
   @interface MyXWalkExtension : XWalkExtension
   
   @end
   
   @interface MyXWalkExtension ()
   
   - (void) jsfunc_myFunction:(UInt32*)callId message:(NSString *)myVariable;
   
   @end
   
   @implementation MyXWalkExtension
   
   - (void) jsfunc_myFunction:(UInt32*)callId message:(NSString *)myVariable {
   
   NSLog(@"MY VARIABLE: %@", myVariable);
   
   }
   
   @end
   

3. Added extensions.plist (couldn't find better way to display .plist content) to CocoaTouch framework project as follows:

   <plist>
   
   <dict>
   
       <key>XWalkExtensions</key>
   
       <dict>
   
           <key>xwalk.myxwalkextension.MyXWalkExtension</key>
   
           <string>MyXWalkExtension</string>
   
       </dict>
   
   </dict>
   
   </plist>
   

4. Added manifest.plist to the CocoaTouch framework project:

   <plist>
   
   <dict>
   
       <key>xwalk_extensions</key>
   
       <array>
   
           <key>item 0</key>
   
           <string>xwalk.myxwalkextension.MyXWalkExtension</string>
   
       </array>
   
   </dict>
   
   </plist>
   

5. Calling from javascript as follows:

   xwalk.myxwalkextension.MyXWalkExtension.myFunction('100');
   

I checked whether the above javascript code's block is executing or not & it is executing, but am not getting log in my xcode logging console. Because I think that the jsfunc_myFunction is not getting called from javascript. I don't know what am I missing or doing wrong. I am following crosswalk project website. I know that we don't need to extend Crosswalk runtime in case of Android where we can call Android native methods from javascript by providing a javascript interface, but in iOS it is not the case. So, I decided to extend Crosswalk runtime. The crosswalk project website is not much descriptive & detailed. Am I forgetting to embed the extension in my project, if yes, how do I do it?

Answer 1

[XWalkExtensionFactory register:@"xwalk.myxwalkextension.MyXWalkExtension" cls:[MyXWalkExtension class]];
//where xWalkView is XWalkView (Crosswalk's WebView).
[self.xWalkView loadExtension:[XWalkExtensionFactory createExtension:@"xwalk.myxwalkextension.MyXWalkExtension"] namespace:@"xwalk.myxwalkextension.MyXWalkExtension"];

I had to load my XWalkExtension & embed it into the app in ViewController.m.
