Just verified this today  but if you are trying to open a Facebook page  you can use  fb   page  Page ID    Page ID can be found under your page in the about section near the bottom   Specific to my use case  in Xamarin Forms  you can use this snippet to open in the app if available  otherwise in the browser   Device OpenUri new Uri  fb   page  id

I know the question is old  but in support of the above answers i wanted to share my working code  Just add these two methods to whatever class The code checks if facebook app is installed  if not installed the url is opened in a browser And if any errors occur when trying to find the profileId  the page will be opened in a browser  Just pass the url example  http   www facebook com AlibabaUS  to  openUrl  and it will do all the magic  Hope it helps someone       NOTE  UrlUtils was the class that had the code for me  you might have to change it to something else to suite your needs      void  openUrlInBrowser  NSString    url       if  url length  gt  0            NSURL  linkUrl    NSURL URLWithString url             UIApplication sharedApplication  openURL linkUrl             void  openUrl  NSString    urlString          check if facebook app exists     if    UIApplication sharedApplication  canOpenURL  NSURL URLWithString   fb                      Facebook app installed         NSArray  tokens    urlString componentsSeparatedByString                NSString  profileName    tokens lastObject              call graph api         NSURL  apiUrl    NSURL URLWithString  NSString stringWithFormat   https   graph facebook com     profileName            NSData  apiResponse    NSData dataWithContentsOfURL apiUrl            NSError  error   nil          NSDictionary  jsonDict    NSJSONSerialization JSONObjectWithData apiResponse options NSJSONReadingMutableContainers error  amp error              check for parse error         if  error    nil                 NSString  profileId    jsonDict objectForKey   id                 if  profileId length  gt  0     make sure id key is actually available                 NSURL  fbUrl    NSURL URLWithString  NSString stringWithFormat   fb   profile     profileId                      UIApplication sharedApplication  openURL fbUrl                             else                   UrlUtils openUrlInBrowser urlString                                    else   parse error occured              UrlUtils openUrlInBrowser urlString                        else   facebook app not installed          UrlUtils openUrlInBrowser urlString

To add yonix   s comment as an answer  the old fb   page     URL no longer works  Apparently it was replaced by fb   profile      even though a page is not a profile

I did this in MonoTouch in the following method  I m sure a pure Obj-C based approach wouldn t be too different  I used this inside a class which had changing URLs at times which is why I just didn t put it in a if elseif statement   NSString  myUrls     fb   profile 100000369031300 http   www facebook com ytn3rd   NSArray  urls    myUrls componentsSeparatedByString        for  NSString  url in urls       NSURL  nsurl    NSURL URLWithString url       if    UIApplication sharedApplication  canOpenURL nsurl              UIApplication sharedApplication  openURL nsurl           break            The break is not always called before your app changes to Safari Facebook  I assume your program will halt there and call it when you come back to it
