libgdx和robovm，打开Facebook共享对话框

Question

Does anyone have a working example of using robovm(and facebook robopods i assume) to open the facebook share dialog on IOS? I have tried every solution I can find with no success :( All solutions use something along the line of:

 dialog = new FBSDKShareDialog();
 dialog.setFromViewController(getWindow().getRootViewController());
 dialog.setShareContent(content);
 dialog.show();

But it always crashes at the dialog.show part.

Answer 1

The show method can only be called in the main queue (I believe it is the same as the ui thread). You can force it there using the following example:

final FBSDKShareDialog dialog = new FBSDKShareDialog();
dialog.setShareContent(content);
dialog.setFromViewController(application.getRootApplication().getUIViewController());


NSOperationQueue.getMainQueue().addOperation(new Runnable() {
    @Override
    public void run() {
        if (dialog.canShow())
            dialog.show();
        //else
        //    fallback();
    }
});
