iOS6中的Facebook集成错误(Accounts.framework)

Question

我使用以下代码(在WWDC 2012视频中显示):

 self.accountStore = [[ACAccountStore alloc] init];

    ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    [self.accountStore requestAccessToAccountsWithType:facebookAccountType
                                 withCompletionHandler:^(BOOL granted, NSError *e) {
                                     if (granted)
                                     {
                                         NSArray *accounts = [self.accountStore
                                                              accountsWithAccountType:facebookAccountType];
                                         self.facebookAccount = [accounts lastObject];
                                     } else {
                                         // Fail gracefully...
                                     }
                                 }];

我还在NSDictionary我的.plist文件中添加了:

所以,我的问题是我收到以下异常:

 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Access options are required for this account type.'

我试过这个ACAccountTypeIdentifierTwitter和ACAccountTypeIdentifierSinaWeibo.我没有收到任何例外,尽管他们总是回来granted == NO

好吧,WWDC 2012显示了一件事,但文档显示了另一个......他们正在使用的方法现已弃用:

– requestAccessToAccountsWithType:withCompletionHandler: Deprecated in iOS 6.0

你应该做什么:

ACAccountType *facebookAccountType = [self.accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

    NSDictionary *options = @{
    @"ACFacebookAppIdKey" : @"123456789",
    @"ACFacebookPermissionsKey" : @[@"publish_stream"],
    @"ACFacebookAudienceKey" : ACFacebookAudienceEveryone}; // Needed only when write permissions are requested

    [self.accountStore requestAccessToAccountsWithType:facebookAccountType options:options 
                                 completion:^(BOOL granted, NSError *error) {
                                     if (granted)
                                     {
                                         NSArray *accounts = [self.accountStore
                                                              accountsWithAccountType:facebookAccountType];
                                         self.facebookAccount = [accounts lastObject];
                                     } else {
                                         NSLog(@"%@",error);
                                         // Fail gracefully...
                                     }
                                 }];
