NavigationController initWithRootViewController dealloc

I have some pretty simple code where I am using a UINavigationController and adding a rootViewControll开发者_运维问答er. After some processing has occurred I want to pop off the current view controller and replace it with another one. This seems to work fine, but my original view controller does not dealloc. I set a breakpoint in it's dealloc and it never gets hit. Below is my code. Not sure why happens. Just for testing if I release startController twice it does go away.

StartViewController *startController = [[StartViewController alloc] initWithNibName:@"StartViewController" bundle:[NSBundle mainBundle]]; 

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:startController];
    [nav pushViewController:startController animated:NO];

    self.navController = nav;

    [startController release];
    [nav release];

Thanks any help.

Your ultimate goal is to bring the view controller's retain count to zero. So make sure that everything the view retains is released and anywhere the view is retained also release.

Please check the following possible causes:

1. Make sure you pop the view controller from the navController if you have a custom back button. The default Back button will work fine.

2. Make sure that all your IBOutlets are set to nil in viewDidUnload

   - (void)viewDidUnload 
   {
      [super viewDidUnload];
      self.webView = nil;
   }
   

3. If your view is an observer to a model class to receive events

For example

model.addObserver(myView);

and sure to also do

model.removeObserver(myView);

I hope this helps.

It looks as though your self.navController has got a holding reference to it. maybe put

self.navController =nil; 

somewhere appropriate, so that when the view has been popped it is released.

I was trying to pop off the root view controller. I instead used the setViewControllers message from the UINavigationController object to replace all my view controllers.
