Share on facebook when app is not configured - ios

Question

I want post something on Facebook. I have used SLComposeViewController for that. I just want to ask how can i share if user hasn't configured its app in phone.
Is there any way that I open it in browser and then post anything. Consider I want to post any string say "hello there" . So i keep this string , open safari and login there . After I am logged in the string is posted automatically
if SLComposeViewController.isAvailableForServiceType(SLServiceTypeFacebook) {
let fbShare:SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
fbShare.completionHandler = {
result in
switch result {
case SLComposeViewControllerResult.Cancelled:
//Code to deal with it being cancelled
break
case SLComposeViewControllerResult.Done:
//Code here to deal with it being completed
break
}
}
refrenceViewController.presentViewController(fbShare, animated: true, completion: nil)
} else {
//open safari and post it there
}

I used the following code to post videos to facebook. You can use similar approach to post your text.
NSData *data = [NSData dataWithContentsOfURL:outputFileURL];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
data, #"video.mp4",
#"video/mp4", #"contentType",
caption, #"description",
nil];
/* make the API call */
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
initWithGraphPath:#"/me/videos"
parameters:params
HTTPMethod:#"POST"];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection,
id result,
NSError *error) {
if(!error) {
DDLogDebug(#"result %#",result);
} else {
DDLogError(#"error description : %#",error.description);
[Helper showToast:[NSString stringWithFormat:#"Unable to share to Facebook : Error: %#",[error localizedDescription]] withDuration:1];
}
}];
of course before this you need to make sure that you already have the FBSDKAccess token granted. You can check the full documentation from facebook sdk
