问题描述

使用FBLoginView时，调用initWithReadPermission后，我需要重新授权发布流.我尝试在委托函数内部调用，以获取用户信息.在下一个对话框要求发布流权限之后，该应用程序向我抛出了一个异常，内容为

I have a problem of reauthorizating the publish stream after calling the initWithReadPermission when using FBLoginView. I try to call inside the delegate function where i can get the user information. After the next dialog asking for publish stream permission, the application threw me an exception saying

'com.facebook.sdk:InvalidOperationException'，原因:"FBSession:在先前的重新授权调用尚未完成的情况下，重新授权无效." "

我需要在获得读取权限后致电，但是如何防止出现此问题?
