Question

我正在尝试使用iOS 6的新Facebook集成API查询有关用户的信息。这是我正在使用的代码，它与他们在WWDC上演示的内容完全相同：

{
NSDictionary *parameters = @{};
NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
                                        requestMethod:SLRequestMethodGET
                                                  URL:url
                                           parameters:parameters];
request.account = self.account;
[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    NSLog(@"Facebook request received, status code %d", urlResponse.statusCode);
    NSString *response = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
    NSLog(@"Response data: %@", response);
    dispatch_async(dispatch_get_main_queue(), ^{

    });
}];
}

问题是我从Facebook收到错误代码2500：“必须使用活动访问令牌来查询有关当前用户的信息。”如果我将查询更改为https://graph.facebook.com/[facebook id]，那么它可以正常工作。我假设问题是iOS在通过requestForServiceType发送请求时传递应用程序的访问令牌而不是用户的访问令牌。我只是不知道如何解决它。显然，预测和硬编码我的用户的Facebook ID不是一种选择。有什么建议？

Answer 1

在参数中添加您的活动访问令牌，例如

NSDictionary *parameters = [NSDictionary dictionaryWithObject:@"PUT_ACCESS_TOKEN_HERE" forKey:@"access_token"];

Answer 2

好的就是我如何与iOS 6进行这种集成并从Facebook获得我想要的东西：

在AppDelegate中我这样做：

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {
    return [FBSession.activeSession handleOpenURL:url];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [FBSession.activeSession handleDidBecomeActive];
}

- (void)applicationWillTerminate:(UIApplication *)application
{
    [FBSession.activeSession close];
}

在我的ViewController中，我想要检索有关我自己或朋友的信息，我这样做（注意：这是一个测试，所以它有很多权限！）：

NSArray *permissions =
    [NSArray arrayWithObjects:@"email", @"user_location",
     @"user_birthday",
     @"user_likes", @"user_interests",@"friends_interests",@"friends_birthday",@"friends_location",@"friends_hometown",@"friends_photos",@"friends_status",
     @"friends_about_me", @"friends_birthday", @"friends_hometown", @"friends_interests", @"friends_likes", @"friends_location", nil];

    [FBSession openActiveSessionWithReadPermissions:permissions
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                      /* handle success + failure in block */
                                      if (status) {
                                          NSLog(@"Facebook Read Permission is successful!");
                                          [self presentPostOptions];

                                          //   [self presentPostOptions];


                                      }
                                  }];

然后在“presentPostOptions”中我这样做（在这个例子中我试图从我的朋友那里检索一些东西）：

- (void)presentPostOptions
{

    [[FBRequest requestForMyFriends] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error)

     {

         if (!error) {

NSArray *data = [user objectForKey:@"data"];
             NSLog(@"%d", [data count]);
             for (FBGraphObject<FBGraphUser> *friend in data) {
                 NSLog(@"%@", [friend first_name]);
                 NSLog(@"%@", [friend last_name]);
                 NSLog(@"%@", [friend id]);
                 //make sure you have FBProfilePictureView outlet in your view
                 //otherwise skip the profile picture!
                 self.fbProfilePic.profileID = @"you'r friend's profile.id";

             }
         }
         else
         {
             NSLog(@"error");
             //  [self didFailWithError:error];
         }
     }];

我不知道你还想做什么，因为在你的问题中你只是试图建立连接，但这样你就可以在iOS 6中集成任何你想要的东西。

还有一件事，请确保您在Facebook上的应用设置以及那里的配置，例如启用iOS应用和iPhone / iPad ID。还有你的plist中的FacebookAppID。

让我知道它是否适合您，

编辑：顺便说一句，我的Facebook SDK是3.1.1。

Answer 3

我有相同的错误消息，我在续订凭证后通过保存我的帐户来修复它。

Answer 4

确保您的（ACAccount *）facebookAccount（或在您的情况下为self.account） 对象很强大，你在获得权限时正确设置它。

Answer 5

答案很简单

在viewDidLoad（）中使用：

accountStore= [[ACAccountStore alloc]init];
facebookAccountType= [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

NSDictionary *options= @{
ACFacebookAudienceKey: ACFacebookAudienceEveryone,
ACFacebookAppIdKey: @"<YOUR FACEBOOK APP ID>",
ACFacebookPermissionsKey: @[@"public_profile"]

                          };    

[accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error) {

    if (granted) {
        NSLog(@"Permission has been granted to the app");
        NSArray *accounts= [accountStore accountsWithAccountType:facebookAccountType];
        facebookAccount= [accounts firstObject];
        [self performSelectorOnMainThread:@selector(facebookProfile) withObject:nil waitUntilDone:NO];

    } else {
        NSLog(@"Permission denied to the app");
    }
}];

功能 - （无效）facebookProfile

NSURL *url = [NSURL URLWithString:@"https://graph.facebook.com/me"];

请注意，您需要的参数被添加为字典请参阅下面的完整列表 https://developers.facebook.com/docs/graph-api/reference/user

NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:@"picture,id,name",@"fields", nil];

SLRequest *profileInfoRequest= [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:url parameters:param];
profileInfoRequest.account= facebookAccount;


[profileInfoRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
    NSLog(@"Facebook status code is : %ld", (long)[urlResponse statusCode]);

    if ([urlResponse statusCode]==200) {

        NSDictionary *dictionaryData= [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];



    } else {

    }
}];


}
