获取“错误代码8”当呼叫[ACAccountStore requestAccessToAccountsWithType] - iOS Facebook [英] Getting "Error Code 8" When Calling [ACAccountStore requestAccessToAccountsWithType] - iOS Facebook

问题描述

我一直在搜索Google和SO，找不到com.apple.accounts错误代码8的含义。我试图使用iOS 6和Facebook SDK。

I have been searching Google and SO and cannot find what com.apple.accounts Error Code 8 means. I am attempting to use iOS 6 and the 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：

code> ERR：Error Domain = com.apple.accounts Code = 8操作无法完成（com.apple.accounts错误8。）

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，授予永远不会返回true。任何想法都将非常感激。

No matter what I do, granted never returns true. Any ideas would be very much appreciated.

如果我绕过 if（授予）并调用此函数：

If I bypass the if(granted) and call this function:

- (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JSON：
{error：{message：必须使用活动的访问令牌来查询当前用户的信息，type：OAuthException，code：2500}}}

Then I see this JSON that is returned by Facebook: {"error":{"message":"An active access token must be used to query information about the current user.","type":"OAuthException","code":2500}}}

更新：所以，错误表示客户端的访问信息字典有不正确或缺失的值。但是我不知道这是什么意思。

Update: So, the error means "The client's access info dictionary has incorrect or missing values." but I do not know what that means.

推荐答案

您的选项字典中有错误。

There is an error in your options dictionary.

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

阅读更好的方法声明：具有对象和键的字典，所以首先是对象，然后键。 ..但是你已经插入了第一个KEYS然后OBJECTS（错误的顺序： - ）

read better the method declaration: "dictionary with object and keys", so first object, then key...but you have inserted first KEYS and then OBJECTS (wrong order :-)

正确的字典是：

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

或声明字典文字：

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