Answer 1

您不能保存或删除未经身份验证的 PFUser。实现该功能的方法是为公共(public)读/写用户变量设置一个单独的类

从解析文档 -

Security For User Objects

The PFUser class is secured by default. Data stored in a PFUser can only be modified by that user. By default, the data can still be read by any client. Thus, some PFUser objects are authenticated and can be modified, whereas others are read-only.

Specifically, you are not able to invoke any of the save or delete methods unless the PFUser was obtained using an authenticated method, like logIn or signUp. This ensures that only the user can alter their own data.
