Question

我希望从Facebook和好友列表中获取用户ID，与朋友ID＆amp;个人资料图片朋友的网址。我有两个代码示例，首先是

NSDictionary *params = @{@"fields": @"name, id, picture"};
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:@"/me/friends" parameters:params HTTPMethod:@"GET"];

这也会返回朋友的个人资料图片网址，但不会返回用户自己的Facebook ID。第二是

[[[FBSDKGraphRequest alloc] initWithGraphPath:@"/me" parameters:@{@"fields": @"id,name,friends, picture"}]

这会返回用户的Facebook ID，朋友列表，但不会返回朋友的个人资料图片网址。你能帮我解决这个问题，我怎样才能在一次通话中得到这两件事？

Answer 1

请使用以下代码段：

-(void)getFacebookFriednData{

    FBSDKLoginManager *fbSdkLoginManager = [[FBSDKLoginManager alloc] init];
    [fbSdkLoginManager logOut];    
    [fbSdkLoginManager logInWithReadPermissions:@[@"email",@"public_profile",@"user_friends"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
        if (!error) {
            if (!result.isCancelled) {
                NSDictionary *params = @{@"fields":@"id,name,email,picture,friends"};
                FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                              initWithGraphPath:@"me"
                                              parameters:params
                                              HTTPMethod:@"GET"];
                [SVProgressHUD show];
                [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                    [SVProgressHUD dismiss];
                    if (!error) {

                       NSLog(@"%@",result); // here u get all require data              
                    }
                }];
            }
        }else{
            NSLog(@"%@",error.localizedDescription);  ?/ Handle Error Here.
        }
    }];

}

这是我为使用我的应用的朋友获取此信息的方式

if ((FBSDKAccessToken.current()) != nil){

    if let request = FBSDKGraphRequest(graphPath: "me/friends", parameters: ["fields": "email, name, gender, picture"] ) {
         request.start(completionHandler: { (connection, result, error) in

             if (error == nil){
                  guard let userInfo = result as? [String: Any] else { return } //handle the error
                  print("data------:\(userInfo)")
             } else {

                  //handle any errors

             }
        }
    }
}

userInfo包含您需要的数据。

您可以使用此代码：

NSString *pictureURL = [NSString stringWithFormat:@"https://graph.facebook.com/%@/picture?type=large&return_ssl_resources=1", facebookID];

iOS获得用户的Facebook ID＆amp;朋友列表与朋友的个人资料图片网址
