当应用退出时，Facebook SDK iOS应用保持登录状态

Question

Currently I'm using the below if statement to check if the user has an open session to facebook through my app.

if (FBSession.activeSession.isOpen) {
     // post to wall
}
else {
     [appDelegate openSessionWithAllowLoginUI:YES];
}

If the user quits the app then the session is closed and my if statement opens a new session, however I would like to keep the session open even if the user quits the app.

I tried removing [FBSession.activeSession close] from applicationWillTerminate: however this didn't work.

Answer 1

You can't logout fully. but you can clear all detail of last session by below code.

[FBSession.activeSession closeAndClearTokenInformation];

you can write it according to your requirement either in applicationDidEnterBackground or applicationWillTerminate.

Thanks
