ios - 迁移后解析未经授权的登录

我正在尝试使用ParseFacebookUtilsV4通过Facebook登录，并不断收到错误消息:Error Domain=Parse Code=0 "unauthorized" UserInfo={error=unauthorized, NSLocalizedDescription=unauthorized, temporary=0}。

我只是从Parse迁移到back4app，并且没有更改太多代码，至少与登录有关。我已经在back4app中输入了所有密钥，并使用以下命令重新路由服务器:

let configuration = ParseClientConfiguration {
     $0.applicationId = "appID"
     $0.clientKey = "clientID"
     $0.server = "https://parseapi.back4app.com"
}
Parse.initializeWithConfiguration(configuration)

我该如何解决？

最佳答案

据我所知，swift的初始化设置略有变化，如果您这样做，它似乎可以工作:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let configurationOptions = ParseClientConfiguration {
    $0.applicationId = "APP_ID"
    $0.clientKey = "CLIENT_KEY"
    $0.server = "https://parseapi.back4app.com"
}
Parse.initialize(with: configurationOptions)
return true
}
