Facebook api swift当前用户为零 [英] Facebook api swift current user is nil

问题描述

我有一个Facebook的api问题。登录和成功解除用户令牌后，我遇到用户个人资料有问题：没有。

  func updateLoginStatus（）{
如果let _ = AccessToken.current {
 let currentUser = UserProfile.current 
 userName.text = currentUser？.fullName 
 userPictureView = UserProfile.PictureView（frame：blankUserImage.frame，profile： currentUser）
 userPictureView！.clipsToBounds = true 
 userPictureView！.layer.cornerRadius = userPictureView！.bounds.width / 2 
 popUpView.addSubview（userPictureView！）
 isLogged = true 
 updateLabels（）
} else {
 isLogged = false 
 userPictureView？.removeFromSuperview（）
 updateLabels（）
} 
} 
  

即使我尝试通过使用获取个人资料手册，让userProfile = UserProfile（userId :( AccessToken.current？.userId）！）它在所有参数上都为零，但是h ave初始化用户。有趣的部分是用UserProfile.current它已经取得用户图片。它可以是什么？如何通过其他方法获得完整的用户名？

解决方案

这个问题在android中也发生了。
您应该在访问令牌后加载配置文件（在android中监听配置文件更改）。
我写了一个样本，只是在swift 3，Facebook iOS SDK 4.21.0中测试。
那么你可以得到updatedUser。

  if let _ = FBSDKAccessToken.current（）{
 if let currentUser = FBSDKProfile.current（）{
 print（current user got：\（currentUser））
} else {
 print（current user not got）
 FBSDKProfile.loadCurrentProfile（完成：{
 profile，
中的错误，如果let updatedUser = profile {
 print（finally got user：\（updatedUser））
} else { 
 print（当前用户还没有）
} 
}）
} 
} 
  

I have a problem with Facebook api. After login and success unwrapping user token I have a problem with taking user profile: it's nil.

func updateLoginStatus() {
    if let _ = AccessToken.current {
        let currentUser = UserProfile.current
        userName.text = currentUser?.fullName
        userPictureView = UserProfile.PictureView(frame: blankUserImage.frame, profile: currentUser)
        userPictureView!.clipsToBounds = true
        userPictureView!.layer.cornerRadius = userPictureView!.bounds.width/2
        popUpView.addSubview(userPictureView!)
        isLogged = true
        updateLabels()
    } else {
        isLogged = false
        userPictureView?.removeFromSuperview()
        updateLabels()
    }
}

Even if I try to get profile manual by using let userProfile = UserProfile(userId: (AccessToken.current?.userId)!) it also take nil at all parameters, but it have initialized user. Funny part is that with that UserProfile.current it have take user picture. What it can be? How I can get full user name by other methods?

解决方案

This problem happend in android too. You should load profile (listen profile change in android) after you got access token. I write a sample and just tested in swift 3, Facebook iOS SDK 4.21.0. Then you can got updatedUser.

if let _ = FBSDKAccessToken.current() {
    if let currentUser = FBSDKProfile.current() {
        print("current user got: \(currentUser)")
    } else {
        print("current user not got")
        FBSDKProfile.loadCurrentProfile(completion: {
            profile, error in
            if let updatedUser = profile {
                print("finally got user: \(updatedUser)")
            } else {
                print("current user still not got")
            }
        })
    }
}
