You need to set storyboard Id from storyboard identity inspector   AddTaskViewController  add  self storyboard instantiateViewControllerWithIdentifier   storyboard id      self presentViewController add animated YES completion nil

your code     AddTaskViewController  add     AddTaskViewController alloc  init     self presentViewController add animated YES completion nil     this code can goes to the other controller   but you get a new viewController   not the controller of your storyboard  you can do like this    AddTaskViewController  add    self storyboard instantiateViewControllerWithIdentifier   YourStoryboardID     self presentViewController add animated YES completion nil

If you re using a storyboard  you probably shouldn t be using alloc and init to create a new view controller  Instead  look at your storyboard and find the segue that you want to perform  it should have a unique identifier  and if not  you can set one in the right sidebar    Once you ve found the identifier for that segue  send your current view controller a -performSegueWithIdentifier sender message    self performSegueWithIdentifier   mySegueIdentifier  sender self     This will cause the storyboard to instantiate an AddTaskViewController and present it in the way that you ve defined for that segue     If  on the other hand  you re not using a storyboard at all  then you need to give your AddTaskViewController some kind of user interface  The most common way of doing so is to initialize the controller with a nib  instead of just calling init  you ll call -initWithNibName bundle  and provide the name of a  xib file that contains your add-task UI   AddTaskViewController  add     AddTaskViewController alloc                                initWithNibName   AddTaskView  bundle nil    self presentViewController add animated YES completion nil      There are other  less common  ways of getting a view associated with your new view controller  but this will probably present you the least trouble to get working

If you are using Storyboard and your  add  viewController is in storyboard then set an identifier for your  add  viewcontroller in settings so you can do something like this   UIStoryboard  storyboard    UIStoryboard storyboardWithName   NameOfYourStoryBoard                                                        bundle nil   AddTaskViewController  add                storyboard instantiateViewControllerWithIdentifier   viewControllerIdentifier      self presentViewController add                     animated YES                   completion nil     if you do not have your  add  viewController in storyboard or a nib file and want to create the whole thing programmaticaly then appDocs says      If you cannot define your views in a storyboard or a nib file  override the loadView method to manually instantiate a view hierarchy and assign it to the view property
