Does the same, but in Objective-C:
做同样的事情，但在 Objective-C 中：
[[[FBSDKLoginManager alloc] init] logOut];
[[[FBSDKLoginManager alloc] init] logOut];
Do not forget imports: FBSDKCoreKit/FBSDKCoreKit.h& FBSDKLoginKit/FBSDKLoginKit.h
不要忘记导入：FBSDKCoreKit/FBSDKCoreKit.h&FBSDKLoginKit/FBSDKLoginKit.h

Also, if you have used Parseand the Facebook iOS SDK version >= 4.4.0to sign up or log in a user via Facebook, please use instead:
此外，如果您使用Parse和Facebook iOS SDK 版本 >= 4.4.0通过Facebook注册或登录用户，请改用：
PFUser.logOut()
It will log out the user, delete the session on the Parseback-end side (do not forget to enableParse revocable sessionvia your Parse app settings), plus it will also delete the Facebooksession written on the user device's disk.
它将注销用户，删除Parse后端的会话（不要忘记通过 Parse 应用程序设置启用Parse可撤销会话），此外它还将删除写入用户设备磁盘的Facebook会话。
I hope this answer will help you guys.
我希望这个答案对你们有帮助。
