ios - 如何获取 Facebook 用户的验证状态

Question

我使用适用于 iOS 的 Facebook SDK 与 HelloFacebookSample 合作，从用户帐户中检索已验证的状态。

我试图在下面的方法中从用户实例中检索。但它似乎没有
在那里定义。

如何检索已验证状态？

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {
    // here we use helper properties of FBGraphUser to dot-through to first_name and
    // id properties of the json response from the server; alternatively we could use
    // NSDictionary methods such as objectForKey to get values from the my json object
    self.labelFirstName.text = [NSString stringWithFormat:@"Hello %@!", user.first_name];
    // setting the profileID property of the FBProfilePictureView instance
    // causes the control to fetch and display the profile picture for the user
    self.profilePic.profileID = user.id;
    self.loggedInUser = user;
}

我得到了答案：

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {
    // here we use helper properties of FBGraphUser to dot-through to first_name and
    // id properties of the json response from the server; alternatively we could use
    // NSDictionary methods such as objectForKey to get values from the my json object
    self.labelFirstName.text = [NSString stringWithFormat:@"Hello %@!", user.first_name];
    // setting the profileID property of the FBProfilePictureView instance
    // causes the control to fetch and display the profile picture for the user
    self.profilePic.profileID = user.id;
    self.loggedInUser = user;

    NSLog(@"userInfo %@",[user objectForKey:@"verified"]);

}
