You have two methods to logout. First, as suggested by Inder Kumar Rathore
您有两种注销方法。首先，正如 Inder Kumar Rathore 所建议的
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logOut];
Second is by setting the currentAccessToken to nil
其次是通过将 currentAccessToken 设置为 nil
[FBSDKAccessToken setCurrentAccessToken:nil];
@cookiemonsta hope second method works for you.
@cookiemonsta 希望第二种方法适合你。

FBSDKLoginManageris your need, it has logOutmethod but you might have to use your custom login
FBSDKLoginManager是您的需要，它有logOut方法，但您可能必须使用自定义登录
e.g.
例如
FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
[loginManager logInWithReadPermissions:@[@"email"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
// Process error
} else if (result.isCancelled) {
// Handle cancellations
} else {
// If you ask for multiple permissions at once, you
// should check if specific permissions missing
if ([result.grantedPermissions containsObject:@"email"]) {
// Do work
}
}
}];
//then logout
[loginManager logOut];

Swift version:
迅捷版：
FBSDKLoginManager().logOut()
You can use FBSDKLoginManagereven if you logged in with FBSDKLoginButton.
您可以使用FBSDKLoginManager，即使您登录时FBSDKLoginButton。

I would like to use the code mentioned over here, How to logout user using Facebook authentication using Swift and iOS?
我想使用这里提到的代码， 如何使用 Swift 和 iOS 使用 Facebook 身份验证注销用户？
where HardikDG mentioned a good answer for logout. what you need to do is add below line before the login happen,
HardikDG 在那里提到了一个很好的注销答案。您需要做的是在登录之前添加以下行，
fbLoginManager.loginBehavior = FBSDKLoginBehavior.web
and while logout use below code
并在注销时使用下面的代码
FBSDKAccessToken.setCurrent(nil)
FBSDKProfile.setCurrent(nil)
FBSDKLoginManager().logOut()
this works perfectly for me.
这对我来说非常有效。
