Facebook iOS本机应用程序中的“权限”对话框

Question

I'm using Facebook iOS SDK 3.5 to log-in into my app, the following method is invoked:

FBSession openActiveSessionWithReadPermissions

If native iOS login is not enabled and facebook iOS app is installed, the login process will get redirected to the facebook app. The problem is that every single time 'FBSession openActiveSessionWithReadPermissions'is invoked, the facebook app presents the permission dialog to the user, even when the user already authorized the FB app.

The permission list is empty (nil). This problem does not happen if native ios or safari are used to log -in.

Any ideas? Thanks

You can check if the user has successfully logged in by checking for an access token here

Also, you can make sure you aren't popping up a GUI from each call by setting allowLoginUI to false.

+ (BOOL)openActiveSessionWithAllowLoginUI:(BOOL)allowLoginUI;

I've not done any iOS FB stuff myself, but that's what I got from reading the docs.

Also, there seems to be a somewhat related question posted here .
