Ionic cannot open facebook profile page from app

I want to open Facebook’s profile page that corresponds to a user in ionic application. I use cordovaInAppBrowswer plugin.

url = 'fb://profile/vahid.vdn';
var options = {
	location: 'yes',
	clearcache: 'yes',
	toolbar: 'yes'
$ url, '_system', options ).then(function(event) {
    // facebook app is already installed and opened successfully 
.catch(function(event) {
    // facebook app isn't installed in this device
    url = ''
    $ url, '_system', options );

This just open Facebook’s home page in the Facebook app. (Platform: iOS)

Any idea?
