process for logging users out

I have an application that I am building that is doing a ton of stuff when the views load. Is there a method that I can use to reload all of the views when a user logs out so that all of the viewDidLoad content is reloaded?

Primarily this is an issue because I am using the JASidePanel 'plugin' and if I log out and log back in the content is not refreshed for the new user. Thoughts?

Thanks in advance....

one solution is to move that code into viewDidAppear and use a BOOL property (self.refresh for example) to control whether or not it needs to be refreshed or not.

so whenever you log the user out, set that refresh BOOL variable to YES.

- (void)logout {
    [PFuser logout]
    self.refresh = YES;
}

in viewDidAppear you could have something like this:

   if (self.refresh == YES) {

        self.refresh = NO;
        //newly logged in user
       //perform the setup of the view for that new user

} else {

     //refresh is not necessary
}

I am also setting an array that is populating a table view. When I move that array to viewDidAppear the table is not loaded....

I can. I am reluctant too because it may ALL be garbage....still learning. I can clean it up and send. Quick question though. Are you familiar with JASidePanel? Getting that to reload is the real issue...

Is there a way to logout and reset all of the views so that once you login it will re-run the viewDidLoad methods again?

the only way would be to destroy all your views (but im not sure thats good practice) I still think your best option is to either use viewWillAppear, or use the notification center to send notifications to your views when login and logouts occur that run your code then.

The notifications might be the best bet. There was only one example that I remember when I was folloing the ios track. Do you have any good resources for that.

Bottom line, what I am trying to do is to load some data and store it as userDefaults (or the appropriate alternative) in the panel. We have a list of teams there. If you logout and log back in I need those list of teams to be for the current user...not the last user. Notifications are probably the way to go for me.

Thanks for the help!
