- (void) goBack:(NSNotification *) notification {
      // [self.navigationController popViewControllerAnimated:YES];
     //  [self dismissViewControllerAnimated:YES completion:nil];
      [self.navigationController popToRootViewControllerAnimated:YES];
}

你需要使用：

[self.navigationController popToRootViewControllerAnimated:YES];

这将带您回到根视图控制器。

如果你想导航回之前的视图控制器，你应该实现：

[self.navigationController popViewControllerAnimated:YES];

通过使用下面的行，我们可以转到父视图控制器

[self.navigationController popViewControllerAnimated:YES];

通过使用下面的行，我们可以移动到主/根视图控制器

[self.navigationController popToRootViewControllerAnimated:YES];

通过使用下面的行，我们可以移动到任何视图控制器

[self.navigationController popToViewController:viewControllerObject animated:YES];

怎么样...

 [self.navigationController dismissViewControllerAnimated:YES completion:NULL];

假设您当前处于基于导航的控制器中，并且您想在进入基于导航的控制器之前返回上一个控制器。

试试看....

#import "bookdescriViewController.h" // import here your class name 

- (IBAction)backButton:(id)sender 
{
  bookdescriViewController *previosVC = [[bookdescriViewController alloc]init];
  [self.navigationController popViewControllerAnimated:YES]; // go to previous view controller
  [self.navigationController popToRootViewControllerAnimated:YES]; // go to root view controller
  [self.navigationController popToViewController:previosVC animated:YES]; // go to any view controller
  [previosVC release];
}

返回父视图控制器并释放当前视图控制器 ex ：

- (void)applicationDidEnterBackground:(NSNotification *)notification
{
    NSInteger numberOfViewControllers = self.navigationController.viewControllers.count;

    UIViewController *vc = [self.navigationController.viewControllers objectAtIndex:numberOfViewControllers - 2];

    [self.navigationController popToViewController:vc animated:NO];
}

或另一个视图控制器
