iOS Facebook URL方案无法在Facebook应用中打开页面

Question

I need to open facebook page in facebook app.

This is my code

 let url : URL!
 if (UIApplication.shared.canOpenURL(URL(string:"fb://")!)) {
    //FIXME: Url is not working ✋
    let pageName = "google"
      // tried with fb://page?name=%@ not worked
    let urlString =  String.init(format: "fb://page?id=%@",pageName!) 
    url = URL.init(string: urlString)
 } else {
    url = URL.init(string: "https://www.facebook.com/google")
 }

if #available(iOS 10.0, *) {
    UIApplication.shared.open(url!, completionHandler: nil)
} else {
    UIApplication.shared.openURL(url!)
}

it perfectly works in safari browser but not in facebook app.

I have added the url schem in inof.plist

<key>LSApplicationQueriesSchemes</key>
    <array>
        <string>fb</string>
        <string>fbapi</string>
        <string>fb-messenger-api</string>
        <string>fbauth2</string>
        <string>fbshareextension</string>
    </array>

Can anyone help me to get out this problem?

Thanks In Advance!!!!

Answer 1

try this code , make sure use facebook id from page not page name

check this How to find page Id

 let url : URL!
        if (UIApplication.shared.canOpenURL(URL(string:"fb://")!)) {
            //FIXME: Url is not working ✋
            let pageName = "104958162837"
            // tried with fb://page?name=%@ not worked
            let urlString =  String.init(format: "fb://profile/%@",pageName) 
            url = URL.init(string: urlString)
        } else {
            url = URL.init(string: "https://www.facebook.com/104958162837")
        }

        if #available(iOS 10.0, *) {
            UIApplication.shared.open(url!, completionHandler: nil)
        } else {
            UIApplication.shared.openURL(url!)
        }

Answer 2

And is it opening in a browser when you call UIApplication.shared.openURL(:) ?

I didn't exactly understand your problem, but if I'm not mistaken, you've to put the Facebook App ID (it's the first thing that appears in your app in developers.facebook ) in your URL Types.

This image should clarify what I'm trying to say:

Do not forget the "fb" String before your App ID .

EDIT: Now that I've understood your problem, I can't be sure that you will be able to solve this - as you can see all this answers -, they apparently don't seem to work anymore , as the URL scheme changed a couple of times, and the one that you're using is actually the last "answered/used" on the referenced answer. I can almost confirm that there is no supported way to do what you're trying because of this answer in fb-sdk github issues .
