我的应用程序正在请求“进行离线访问”权限，为什么？这是最奇怪的事情。我已经做了一些搜索，还没有真正找到任何有效的方法。我尝试将这些用于范围:
https://www.googleapis.com/auth/plus.profile.emails.read
https://www.googleapis.com/auth/plus.login
这似乎没有帮助。
以下是屏幕截图和一些我的代码来帮助您了解发生了什么:
我的一些代码:

最佳答案
这是从https://stackoverflow.com/questions/32210920/why-is-my-app-asking-for-permission-to-have-offline-access?answertab=oldest#tab-top:
这是正常现象，当用户授予
已经允许。
基本上，除非您真的不想那样，否则不必担心
在这种情况下，您需要取消对用户旧 token 的验证
在请求一个新的。
我不确定如何操作，因为我之前从未做过，但是在您授权一个新 token 之前，您需要先取消对旧 token 的授权。
您需要修改-(void)getUserInfo:(NSString *)token方法。
