cordova ios : facebook link not working

I cannot open facebook page link from my cordova ios app. I am using latest cordova version 6.x.x and I installed InAppBrowser plugin. The issue arises only if facebook app is installed in ios devise. I tried with both fb page name and page id. Both didn't work.

I used the code below,

<a href="#" onClick="cordova.InAppBrowser.open('https://www.facebook.com/pagename', '_system', 'location=yes');">

The same code is working fine in android. Please help..
