在 ios 6 sdk 中获取 facebook 用户详细信息？

Question

如何使用 ios 6 内置的 facebook sdk 检索 facebook 用户详细信息？我尝试了几个示例，但无法正常工作。

- (void) getFBDetails {

if(!_accountStore)
    _accountStore = [[ACAccountStore alloc] init];

ACAccountType *facebookTypeAccount = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];

[_accountStore requestAccessToAccountsWithType:facebookTypeAccount
                                       options:@{ACFacebookAppIdKey: @"514284105262105", ACFacebookPermissionsKey: @[@"email"]}
                                    completion:^(BOOL granted, NSError *error) {
                                        if(granted){
                                            NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
                                            _facebookAccount = [accounts lastObject];
                                            NSLog(@"Success");

                                            [self me];

                                        }else{
                                            // ouch
                                            NSLog(@"Fail");
                                            NSLog(@"Error: %@", error);
                                        }
                                    }];


}


- (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);

}];

}

但这无法从 facebook 获取数据。我的应用 id 是正确的。

这是我收到的错误消息

Error: Error Domain=com.apple.accounts Code=7 "The Facebook server could not fulfill this access request: no stored remote_app_id for app" UserInfo=0x1d879c90 {NSLocalizedDescription=The Facebook server could not fulfill this access request: no stored remote_app_id for app} 

Answer 1

不确定这是否能解决问题，但您是否在应用的 AppName-Info.plist 文件中设置了 Facebook 应用 ID？

所需的密钥是FacebookAppID，其类型为String。 尝试在那里填写您的 App ID 并查看它是否有效。

Answer 2

在 iOS6.0 中，你必须分别询问读写权限。 首先请求读取权限，即电子邮件，然后根据应用要求请求其他权限。

T**o get this code work the bundle Identifier with which you have registered your application with facebook and bundle identifier in application plist file should be same**
