ios - 撤销 token 后 Google SignIn 崩溃

Question

我正在使用 Google 驱动器来允许服务器访问我的驱动器。我使用 SignIn 为传递给它的服务器获取 token ，以便它可以访问驱动器。

我可以正常登录该应用程序，它请求相应的云端硬盘权限。

问题是当我撤销我之前授予使用登录权限的应用程序访问云端硬盘时崩溃。

*** -[GSDK_GTMSessionFetcherService fetcherWithRequest:]: message sent to deallocated instance 0x7ff2706c8440

知道是什么导致了这种情况发生。我找不到解决方案。由于 pod 将代码作为框架分发，因此我无法轻松使用该代码。

我使用的是 GoogleSignIn 4.0.0

这是崩溃期间的堆栈跟踪。

Answer 1

好的，万一有人遇到这个你必须在主线程上登录

dispatch_async(dispatch_get_main_queue(), ^{ 

     [self.signIn signIn];
});

可能会节省一些时间 :)
