ACAccountStore错误6 (ACErrorAccountNotFound)和8

Question

我试图使用以下代码从ACAccountStore获得一个帐户：

- (void) facebookLoginOnSuccess: (void (^)(void)) successBlock onError:(void(^)(NSError *error))errorBlock{

    self.facebookPermissions = @[
        @"offline_access",
        @"publish_stream",
        @"user_birthday",
        @"user_location",
        @"email"
    ];
    
        
    NSDictionary *options = @{
        @"ACFacebookAppIDKey": [[NSBundle mainBundle] objectForInfoDictionaryKey:@"FacebookAppID"],
        @"ACFacebookAppVersionKey": @"1.0",
        @"ACFacebookPermissionsKey": self.facebookPermissions,
        @"ACFacebookPermissionGroupKey": @"write"
    };
    
    [self accountLoginFor:ACAccountTypeIdentifierFacebook withOptions:options OnSuccess:successBlock onError:errorBlock];

}

- (void) accountLoginFor: (NSString *) accountTypeID withOptions: (NSDictionary *) options OnSuccess: (void (^)(void)) successBlock onError:(void(^)(NSError *error))errorBlock{

    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:accountTypeID];
    
    [accountStore requestAccessToAccountsWithType:accountType
                                          options:options
                                       completion:^(BOOL granted, NSError *error){
        if (granted){
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
            NSLog(@"%@",accountsArray);
        }
        else {
            NSLog(@"Error accessing account: %@", [error localizedDescription]);
        }
    }];
    
}

但我发现了一个错误：

Error Domain=com.apple.accounts Code=6 "The operation couldn't be completed. (com.apple.accounts error 6.)"

我找不到任何相关的东西，只有这个问题。有什么不对的吗？

更新

我在Apple Developer Docs上发现了这个。

帐户框架 当请求访问Facebook帐户时，选项字典中唯一需要的键是ACFacebookAppIdKey。ACFacebookPermissionGroupKey和ACFacebookAppVersionKey现在已经过时了。 如果在ACFacebookPermissionsKey、(如publish_stream )下请求写权限，则必须为ACFacebookAudienceKey提供一个值，该值可以是ACFacebookPermissionsKey或ACFacebookAudienceOnlyMe.之一。

所以我改变了我的选择：

    NSDictionary *options = @{
        @"ACFacebookAppIDKey": [[NSBundle mainBundle] objectForInfoDictionaryKey:@"FacebookAppID"],
        @"ACFacebookPermissionsKey": self.facebookPermissions,
        @"ACFacebookAudienceKey": ACFacebookAudienceFriends
    };

但我也犯了同样的错误。

Answer 1

好的，如果您还没有在iOS 6中的设置中设置一个帐户，它会抛出错误代码6。如果用户只是拒绝权限，而不是抛出错误代码7。在第6种情况下，我建议您要求用户首先在设置中设置她的帐户。

NSDictionary *options = @{
ACFacebookAppIdKey: @"1234567890",
ACFacebookPermissionsKey: @[@"publish_stream"],
ACFacebookAudienceKey: ACFacebookAudienceFriends
};

[self.accountStore requestAccessToAccountsWithType:facebookAccountType options:options completion:^(BOOL granted, NSError *error)
{
    if (granted)
    {
        NSArray *accounts = [self.accountStore accountsWithAccountType:facebookAccountType];

        if([accounts count]>0)
            self.facebookAccount = [accounts lastObject];
    }
    else
    {
        dispatch_async(dispatch_get_main_queue(), ^{

            // Fail gracefully...
            NSLog(@"%@",error.description);
            if([error code]== ACErrorAccountNotFound)
                [self throwAlertWithTitle:@"Error" message:@"Account not found. Please setup your account in settings app."];
            else
                [self throwAlertWithTitle:@"Error" message:@"Account access denied."];

        });
    }
}];

jAmi有正确的想法，但我不喜欢代码中的神奇数字。有一个枚举，它内置了数字(ACErrorCode)。

Answer 3

我自己的解决方案是使用Facebook，而不是直接尝试使用库，现在它已经开始工作了。
