iOS Facebook URL 方案无法在 Facebook 应用程序中打开页面

Question

我需要在 Facebook 应用程序中打开 Facebook 页面。

这是我的代码

 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!)
}

它在 safari 浏览器中完美运行，但在 facebook 应用程序中运行不佳。

我在 inof.plist 中添加了 url schem

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

谁能帮我解决这个问题？

提前致谢!!!

试试这段代码，确保使用页面中的 facebook id 而不是页面名称

检查这个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!)
        }
