當調用[ACAccountStore requestAccessToAccountsWithType]時獲取「錯誤代碼8」 - iOS Facebook

Question

我一直在搜索Google和SO，並找不到com.apple.accounts錯誤代碼8的含義。我正在嘗試使用iOS 6和Facebook SDK。

我運行此請求;

if (!_accountStore) _accountStore = [[ACAccountStore alloc] init]; 

ACAccountType *fbActType = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook]; 


NSDictionary *options = [[NSDictionary alloc] initWithObjectsAndKeys: 
         (NSString *)ACFacebookAppIdKey, @"###############", 
         (NSString *)ACFacebookPermissionsKey, [NSArray arrayWithObject:@"email"], 
         nil]; 



[_accountStore requestAccessToAccountsWithType:fbActType options:options completion:^(BOOL granted, NSError *error) { 
              if (granted) { 
               NSLog(@"Success"); 
               NSArray *accounts = [_accountStore accountsWithAccountType:fbActType]; 
               _facebookAccount = [accounts lastObject];              
              } else { 
               NSLog(@"ERR: %@",error); 
               // Fail gracefully... 
              } 
     } 
]; 

我得到這個錯誤：

ERR: Error Domain=com.apple.accounts Code=8 "The operation couldn’t be completed. (com.apple.accounts error 8.)"

不管我做什麼，從不granted返回true。任何想法將非常感激。

如果我繞過if(granted)和調用這個函數：

- (void)me{ 

    NSLog(@"Home.m - (void)me"); 

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

    SLRequest *merequest = [SLRequest requestForServiceType:SLServiceTypeFacebook 
               requestMethod:SLRequestMethodGET 
                 URL:meurl 
               parameters:nil]; 

    merequest.account = _facebookAccount; 

    [merequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { 
     NSString *meDataString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 

     NSLog(@"%@", meDataString); 

    }]; 

然後我看到這個JSON是由Facebook的返回： {"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}}

更新：所以，錯誤的意思是」客戶端訪問信息字典的值不正確或缺失。「但我不知道這意味着什麼。

在您的選項字典中有錯誤。

NSDictionary *options = [[NSDictionary alloc] initWithObjectsAndKeys: 
        (NSString *)ACFacebookAppIdKey, @"###############", 
        (NSString *)ACFacebookPermissionsKey, [NSArray arrayWithObject:@"email"], 
        nil]; 

讀更好的方法聲明：「字典，對象和鍵」，所以第一個對象，然後鍵...但你插入的第一密鑰，然後對象（錯誤的順序:-)

的正確解釋是：

NSDictionary *options = [[NSDictionary alloc] initWithObjectsAndKeys: 
         @"###############", ACFacebookAppIdKey, 
         [NSArray arrayWithObject:@"email"], ACFacebookPermissionsKey, 
         nil]; 

，或者宣告字典文字：

NSDictionary *options = @{ 
           ACFacebookAppIdKey : @"###############", 
           ACFacebookPermissionsKey : [NSArray arrayWithObject:@"email"] 
          };
