iphone - Facebook iOS SDK 不返回用户电子邮件

Question

我正在尝试访问某些用户的信息，包括电子邮件。为此，我使用 Graph API 调用此方法:

[facebook requestWithGraphPath:@"me" andDelegate:self];

它返回用户信息，没有电子邮件信息(生日也不见了)。我设置了所有权限并使用多个帐户(其中包含电子邮件和生日作为公开信息)进行了测试，并接受了所有对话框的请求。

这是我的初始化:

if(!facebook) {
    facebook = [[Facebook alloc] initWithAppId:[self _APP_KEY] andDelegate:self];
    NSArray *array =  [NSArray arrayWithObjects: @"email", @"user_birthday", @"publish_stream", @"offline_access", nil];
    [self setPermissions:array];
}

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
if ([defaults objectForKey:@"FBAccessTokenKey"] && [defaults objectForKey:@"FBExpirationDateKey"]) {
    facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
    facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
}

if (![facebook isSessionValid]) {
    [facebook authorize:permissions];
} 
else {
    [self getUserInfo];
}

登录回调:

- (void)fbDidLogin {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];

    [self getUserInfo];
}

getUserInfo 方法:

- (void) getUserInfo {
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}

请求回调:

 - (void)request:(FBRequest *)request didLoad:(id)result {

    if ([result isKindOfClass:[NSDictionary class]]) {
        NSDictionary* json = result;
        NSLog(@"-> %@", json);
    }
}

结果如下:

-> {
    "first_name" = EDITED (my name);
    gender = male;
    hometown =     {
        id = 111072692249998;
        name = "Porto Alegre";
    };
    id = 653099452;
    languages =     (
                {
            id = 104034306299811;
            name = "Brazilian Portuguese";
        },
                {
            id = 106059522759137;
            name = English;
        }
    );
    "last_name" = EDITED (my last name);
    link = EDITED (my profile);
    locale = "en_US";
    location =     {
        id = 112047398814697;
        name = "S\U00e3o Paulo, Brazil";
    };
    name = EDITED (my name);
    timezone = "-3";
    "updated_time" = "2012-04-25T13:36:51+0000";
    verified = 1;
}

如您所见，没有关于用户电子邮件的信息。我错过了一些步骤吗？有什么想法吗？

提前致谢

尝试使用它，它适用于我的情况

facebook = [[Facebook alloc] initWithAppId:[self _APP_KEY] andDelegate:self]; [facebook authorize:[NSArray arrayWithObjects:@"email",nil]];
