通過新的iOS6社交框架查詢Facebook用戶數據

Question

我想查詢有關使用iOS 6的新Facebook集成API的用戶的信息。這是我使用的代碼，這基本上是相同的，他們演示了在WWDC什麼：

{ 
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(), ^{ 

    }); 
}]; 
} 

問題是我收到的錯誤代碼2500從Facebook：「一個積極的訪問令牌，必須使用查詢有關信息當前用戶「。如果我將查詢更改爲https://graph.facebook.com/ [facebook id]，那麼它工作正常。我假設問題是iOS在通過requestForServiceType發送請求時傳遞應用程序的訪問令牌而不是用戶的訪問令牌。我只是不知道如何解決它。很明顯，對我的用戶的Facebook ID進行預測和硬編碼不是一種選擇。有什麼建議麼？

Answer 1

添加您的積極的訪問令牌在paramete像

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

Answer 2

我有同樣的錯誤信息，我通過更新憑證後，救了我的帳戶固定它。

Answer 3

我面臨着同樣的問題，找到了解決方法：

NSString *uid = [NSString stringWithFormat:@"%@", [[self.account valueForKey:@"properties"] valueForKey:@"uid"]] ;     
NSURL *url = [NSURL URLWithString:[@"https://graph.facebook.com" stringByAppendingPathComponent:uid]]; 

Answer 4

確保您（ACAccount *）facebookAccount（或你的情況self.account） 對象是強大的，你正確設置同時獲得權限。這裏

Answer 5

OK是怎麼做到這一點的整合與iOS 6，並得到我想要的東西從Facebook：

在AppDelegate中我這樣做：

- (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]; 
} 

，並在我的ViewController，我想檢索信息我自己或我的朋友，我這樣做（注：這是一個測試，所以這是一個很大的權限！）：

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]; 


             } 
            }]; 

然後在「presentPostOptions」我這樣做（在這個例子中，我嘗試檢索從我的朋友的東西）：

- (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]; 
     } 
    }]; 

我不知道你想做些什麼，因爲你的問題，你只是試圖做一個連接，但這樣一來，你可以做你想做什麼都當你是集成在iOS 6中。

還有一件事，確保你的應用程序設置通過Facebook和那裏的配置，如啓用你的應用程序的iOS和iPhone/iPad的ID。還有你的plist中的FacebookAppID。

讓我知道，如果它爲你，

編輯：順便說一句我的Facebook SDK 3.1.1是。

Answer 6

答案很簡單

在viewDidLoad中

（）使用方法：

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"); 
    } 
}]; 

而且功能 - （無效）facebookProfile

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

通知您需要的PARAMS被添加作爲字典 參閱以下完整清單 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 { 

    } 
}]; 


}
