ios - 如何从 FacebookLogin 抓取图片

Question

如何打印出来自

的图像

print((result! as AnyObject).value(forKey: "picture.data.url") as? Any)

我知道下面会打印出数据和 url，但我只需要 URL 部分。

print((result! as AnyObject).value(forKey: "picture") as? Any)

有什么建议吗？

我正在使用 FacebookLogin SDK

NOTE: You can create the image URL on your own if you have the userId,

let facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"

这里是你如何从 facebook 登录中获取 id、姓名、电子邮件和个人资料图片 url。我在我的应用程序中使用此代码并且它有效。

func fetchFacebookFields() {
        LoginManager().logIn(permissions: ["email","public_profile"], from: nil) {
            (result, error) -> Void in
            if let error = error {
                print(error.localizedDescription)
                return
            }
            guard let result = result else { return }
            if result.isCancelled { return }
            else {
                GraphRequest(graphPath: "me", parameters: ["fields" : "first_name, last_name, email"]).start() {
                    (connection, result, error) in
                    if let error = error {
                        print(error.localizedDescription)
                        return
                    }
                    if
                        let fields = result as? [String:Any],
                        let userID = fields["id"] as? String,
                        let firstName = fields["first_name"] as? String,
                        let lastName = fields["last_name"] as? String,
                        let email = fields["email"] as? String

                    {
                        let facebookProfileUrl = "http://graph.facebook.com/\(userID)/picture?type=large"
                        print("firstName -> \(firstName)")
                        print("lastName -> \(lastName)")
                        print("email -> \(email)")
                        print("facebookProfileUrl -> \(facebookProfileUrl)")
                        APPDELEGATEOBJ.makeRootVC(vcName : "MainTabBarVC")

                    }
                }
            }
        }
    }
