我的应用请求“离线访问”权限，为什么？这是最奇怪的事情。我做了一些搜索，并没有真正找到任何有效的方法。我已经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。
以下是屏幕截图和我的一些代码，可帮助您了解发生了什么:
我的一些代码:

This is normal behavior and occurs when the user has granted permission already.
Basically, no need to worry about it unless you really don't want that showing up, in that case, you need to un auth the users old token before requesting a new one.
我不确定如何操作，因为我以前没有这样做过，但是在您授权新 token 之前，您需要取消对旧 token 的授权。
您需要修改 -(void)getUserInfo:(NSString *)token 方法。
关于ios - 我的应用正在请求 “Have offline access” 的许可，为什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/32195788/
