ACAccountStore错误6（ACErrorAccountNotFound）和8 [英] ACAccountStore Error 6 (ACErrorAccountNotFound) and 8

问题描述

我正在尝试使用以下代码从ACAccountStore获取帐户：

I'm attempting to get an account from ACAccountStore using the following code:

- (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]);
        }
    }];

}

但我收到此错误：

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

我找不到任何相关内容，只需这个question 。可能出现什么问题？

And I can't find anything related, just this question. Any ideas what could be wrong?

更新

我在Apple开发人员文档。

I found this on the Apple Developer Docs.

帐户框架

请求访问Facebook帐户时，选项词典中唯一需要的密钥是ACFacebookAppIdKey。 ACFacebookPermissionGroupKey和ACFacebookAppVersionKey现已过时。

When requesting access to Facebook accounts, the only key required in your options dictionary is ACFacebookAppIdKey. ACFacebookPermissionGroupKey and ACFacebookAppVersionKey are now obsolete.

如果您在ACFacebookPermissionsKey，，例如publish_stream 下请求写入权限，则您必须为ACFacebookAudienceKey提供一个值，该值可以是 ACFacebookAudienceEveryone ， ACFacebookAudienceFriends ，或 ACFacebookAudienceOnlyMe 。

If you request a write permission under ACFacebookPermissionsKey, such as publish_stream, you must provide a value for ACFacebookAudienceKey, which can be one of ACFacebookAudienceEveryone, ACFacebookAudienceFriends, or ACFacebookAudienceOnlyMe.

所以我将选项更改为：

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

但是我得到了同样的错误。

But I'm getting the same error.

推荐答案

好的，如果您还没有在iOS 6的设置中设置帐户，则会抛出错误代码 6 。如果用户只是拒绝权限，则会抛出错误代码 7 。在案例6中，我建议您要求用户首先在设置中设置她的帐户。

Ok so if you haven't setup an account from your Settings in iOS 6 it throws error code 6. If the user simply denies permission than it throws error code 7. In case 6 i suggest you ask the user to first setup her account in Settings.

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."];

        });
    }
}];
