Question

我刚刚更新了手机iOS11.3和Xcode 9.3，Facebook登录就像我的旧SDK调用一样崩溃：

我不明白这究竟是什么意思，即使它适用于旧版本。 然后我从该页面应用了Swift SDK， https://developers.facebook.com/docs/swift/graph。

import FacebookCore

let connection = GraphRequestConnection()
connection.add(GraphRequest(graphPath: "/me")) { httpResponse, result in
  switch result {
  case .success(let response):
    print("Graph Request Succeeded: \(response)")
  case .failed(let error):
    print("Graph Request Failed: \(error)")
  }
}
connection.start()

这提供了以下错误日志：

FBSDKLog: starting with Graph API v2.4, GET requests for //me should contain an explicit "fields" parameter
Graph Request Failed: Error Domain=com.facebook.sdk.core Code=8 "(null)" UserInfo={com.facebook.sdk:FBSDKGraphRequestErrorCategoryKey=0, com.facebook.sdk:FBSDKGraphRequestErrorHTTPStatusCodeKey=400, com.facebook.sdk:FBSDKErrorDeveloperMessageKey=An active access token must be used to query information about the current user., com.facebook.sdk:FBSDKGraphRequestErrorGraphErrorCode=2500, com.facebook.sdk:FBSDKGraphRequestErrorParsedJSONResponseKey={
    body =     {
        error =         {
            code = 2500;
            "fbtrace_id" = ____id____;
            message = "An active access token must be used to query information about the current user.";
            type = OAuthException;
        };
    };
    code = 400;
}}

它说，必须使用有效的访问令牌来查询有关当前用户的信息。

即使在代码块下面，当我制作词典注释行时也会出现相同的错误，因为它们也不起作用。

import FacebookCore

struct MyProfileRequest: GraphRequestProtocol {
  struct Response: GraphResponseProtocol {
    init(rawResponse: Any?) {
      // Decode JSON from rawResponse into other properties here.
    }
  }

  var graphPath = "/me"
  var parameters: [String : Any]? = ["fields": "id, name"]
  var accessToken = AccessToken.current
  var httpMethod: GraphRequestHTTPMethod = .GET
  var apiVersion: GraphAPIVersion = .defaultVersion
}


let connection = GraphRequestConnection()
connection.add(MyProfileRequest()) { response, result in
  switch result {
  case .success(let response):
    print("Custom Graph Request Succeeded: \(response)")
    print("My facebook id is \(response.dictionaryValue?["id"])")
    print("My name is \(response.dictionaryValue?["name"])")
  case .failed(let error):
    print("Custom Graph Request Failed: \(error)")
  }
}
connection.start()

我该怎么做才能解决这个问题？

最后，我使用下面的方法而不是AppDelegate中的注释open url方法解决了我的问题。希望它能帮助在iOS 11.3中遇到此问题的其他人。

document.addEventListener('touchmove', function(e) {
    e.preventDefault();
}, { passive: false });
