i have a login controller when user enters his username and password and click on the submit button the table view fetches the data from the database and presents the data but the problem is when i click on the left navigation bar item on the navigation ans pop back again to my login controller and enter credentials and click on submit button the tableview is empty.What may be the problem
i think you did a login controller code in viewdidload method. popupviewcontroller work out in viewwillappear:(Bool) method.Better once you login you may hide a backbutton
