Post Score to Facebook IOS

Hello,

I use these codes on android to post the score to facebook, it works well on android. But it doesn’t work on IOS. I couldn’t find what’s the problem. What could be the problem?

        public void ShareScoreOnFB(){
		Application.OpenURL("https://www.facebook.com/dialog/feed?"+
		                    "app_id="+AppID+
		                    "&link="+Link+
		                    "&picture="+Picture+
		                    "&name="+ReplaceSpace(Name)+
		                    "&caption="+ReplaceSpace(Caption)+man.Score+ReplaceSpace(Caption2)+ScoreScene.highscore+
		                    "&description="+ReplaceSpace(Description)+
		                    "&redirect_uri=https://facebook.com/");
}

I use this one for Twitter, this one works on both platform.

public void ShareToTwitter (string textToDisplay)
	{
		Application.OpenURL("http://twitter.com/intent/tweet"+
		                    "?text="+WWW.EscapeURL(textToDisplay)+
		                    "&lang="+WWW.EscapeURL(TWEET_LANGUAGE));
	}

What could be the problem for facebook on IOS?
