ios - 用户注销后 Firebase Facebook 登录按钮不会更改

Question

我目前正在使用 Facebook 作为我的用户登录的登录名。当我的用户必须注销时，我有一个自定义按钮调用我制作的注销方法。当用户注销并返回登录屏幕时，Facebook 按钮应该说登录时仍然说注销。

//my facebook button 
 lazy var facebookLogin:FBSDKLoginButton = {
        let v = FBSDKLoginButton()
        v.translatesAutoresizingMaskIntoConstraints = false
        return v
    }()

// my signout method
    let firebaseAuth = FIRAuth.auth()
do {
  try firebaseAuth?.signOut()
} catch let signOutError as NSError {
  print ("Error signing out: %@", signOutError)
}

Answer 1

只需从FBSDKLoginManager调用logOut()

Logs the user out

This calls [FBSDKAccessToken setCurrentAccessToken:nil] and [FBSDKProfile setCurrentProfile:nil].

// my signout method
let firebaseAuth = FIRAuth.auth()
do {
  try firebaseAuth?.signOut()
  FBSDKLoginManager().logOut()
} catch let signOutError as NSError {
  print ("Error signing out: %@", signOutError)
}

不要忘记在你使用它的类中添加import FBSDKLoginKit
