Question

我一直在搜索Google和SO，但找不到com.apple.accounts错误代码8的含义。我正在尝试使用iOS 6和Facebook SDK。

我运行此请求;

  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...
                                            }
        }
 ];

我收到此错误：

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

无论我做什么，granted永远不会返回true。任何想法都将非常感激。

如果我绕过if(granted)并调用此函数：

- (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);

    }];

然后我看到Facebook返回的这个JSON： {"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}}

更新：因此，错误意味着“客户端的访问信息字典中包含错误或缺失值”。但我不知道这意味着什么。

您的选项词典中有错误。

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

更好地阅读方法声明：“带对象和键的字典”，所以第一个对象，然后是键......但是你已经插入了第一个KEYS然后插入了OBJECTS（错误的顺序： - ）

正确的字典是：

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

或者，声明字典文字：

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

调用[ACAccountStore requestAccessToAccountsWithType]时获取“错误代码8” - iOS Facebook
