self.navigationcontroller popviewcontrolleranimated yes, terminates my app

Question

I have navigation application. I have created a UINavigationController in application didFinishLaunchingWithOptions of appdelegate. self.initialviewcontroller = [[InitialViewController alloc] initWithNibName:@"InitialViewController" bundle:nil]; UINavigationController *myNavController = [[UINavigationController alloc] initWithRootViewController:self.initialviewcontroller];

self.window.rootViewController = myNavController; [self.window makeKeyAndVisible];

In the InitialViewController i have button which will navigate to SecondViewController. So, in the IBAction of button i push the SecondViewController as follows,

if(self.secondView != nil)
  self.secondView = nil;
self.secondView = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil];
self.navigationController pushViewController:self.secondView animated:YES];

Situation : The navigation is working fine, i am bale to navigate between InitialViewController to SecondViewController. When i am in SecondViewController and press home button of device, the application is entered into background and when i reopen the app it opens the app from where i closes(i.e SecondViewController). Now if i press the back button to go to InitialViewController, the app is crashing.

It's working fine in the ios simulator,but crashes occurs on devices.

I didn't understand what the mistake i have done. Please let me know any idea. Thanks in advance....

What is the OS version of your device? As you might seen on the documentation, dismissModalViewControllerAnimated on iOS6. Use dismissViewControllerAnimated:completion: instead. — johnoodles

Try dissmissing your view controller using

[self dismissModalViewControllerAnimated:YES];

It works for me. Even for iOS 6.
