iOS 6 Facebook 不工作

Question

我正在使用这段代码:

_accountStore = [ACAccountStore new];

    ACAccountType *facebookTypeAccount =
    [_accountStore accountTypeWithAccountTypeIdentifier:
     ACAccountTypeIdentifierFacebook];

    NSArray *accounts =
    [_accountStore accountsWithAccountType:
     facebookTypeAccount];

    _facebookAccount = [accounts lastObject];

    [_accountStore requestAccessToAccountsWithType:facebookTypeAccount
                                           options:@{ACFacebookAppIdKey:myKey, ACFacebookPermissionsKey:@[@""]}
                                        completion:^(BOOL granted, NSError *error) {
                                            if(granted)
                                            {
                                                NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
                                                _facebookAccount = [accounts lastObject];
                                                NSLog(@"Success");

                                                [self parseUserDataWithCompletion:completion];
                                            }
                                            else
                                            {
                                                NSLog(@"Error: %@", error);

                                                [self parseUserDataWithCompletion:completion];
                                            }
                                        }];

在设备上工作得很好。但是在模拟器上运行报错:

Error Domain=com.apple.accounts Code=7 "The operation couldn’t be completed. (com.apple.accounts error 7.)"

更新:它也不适用于设备。

它曾经有效。但现在不是了……发生了什么事？ fb 改变了什么吗？

已解决。问题是:

ACFacebookPermissionsKey:@[@""]

必须改为

ACFacebookPermissionsKey:@[]
