编辑:

我想像这样显示我的手机，所以我需要封面照片。从 json 结果我没有得到页面 ID。如何使用iOS SDK获取页面封面图片？

Answer 1

这是一个更新的解决方案。

var basicUserData = ["fields": "cover,picture,id,birthday,email"]

FBRequestConnection.startWithGraphPath("/me",
    parameters: basicUserData,
    HTTPMethod: "GET") {
        (connection:FBRequestConnection!, result, error) -> Void in
            if error != nil {
                print(error!)
            } else {
                print(result!)
            }
        }

Parse 团队建议通过访问 https://graph.facebook.com/(facebookId)/picture?type=large 获取 FB 个人资料图片确保替换为用户的 Facebook Id。 Here is the discussion

注意事项:

• username 字段在 FacebookSDK v2 之后被弃用
• "/me" 是正确的端点而不是 "me"
