ios - 如何在 iOS 上访问 Facebook Graph SDK 的 age_range 属性

Question

如何通过 iOS 访问 age_range Facebook 用户属性 ( https://developers.facebook.com/docs/graph-api/reference/v2.0/user )？其他用户属性很简单(请参阅 Fetching user details from Facebook in iOS )。例如。通过 user.first_name，但是，我不确定如何查询和提取此复合属性的 min 和 max 值。

我相信这是解析年龄范围的方式:

if (status == FBSessionStateOpen) {
    [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary<FBGraphUser> *user, NSError *error) {
        if (error) {
            SSLog( @"Facebook request failure: %@\n", error.description );
        }
        else
        {
            // Look up age range property and put min and max into string "min-max"
            NSDictionary *ageRangeDict = [user objectForKey:@"age_range"];
            NSString *ageRange = [NSString stringWithFormat:@"%@-%@",
                                  [ageRangeDict objectForKey:@"min"],
                                  [ageRangeDict objectForKey:@"max"]];
        }
    }
     ]
}
