您可以使用以下内容。

- (void)viewWillDisappear:(BOOL)animated {
  [super viewWillDisappear:animated];
  NSArray *viewControllers = self.navigationController.viewControllers;
  if (viewControllers.count > 1 && [viewControllers objectAtIndex:viewControllers.count-2] == self) {
    // View is disappearing because a new view controller was pushed onto the stack
    NSLog(@"New view controller was pushed");
  } else if ([viewControllers indexOfObject:self] == NSNotFound) {
    // View is disappearing because it was popped from the stack
    NSLog(@"View controller was popped");
  }
}

当然，这是可能的，因为UINavigationController的视图控制器堆栈(通过viewControlers属性公开)已经在viewWillDisplay被调用时更新。

我认为最简单的方法是：

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    if ([self isMovingFromParentViewController])
    {
        NSLog(@"View controller was popped");
    }
    else
    {
        NSLog(@"New view controller was pushed");
    }
}

Swift：

override func viewWillDisappear(animated: Bool)
{
    super.viewWillDisappear(animated)
    if isMovingFromParentViewController
    {
        print("View controller was popped")
    }
    else
    {
        print("New view controller was pushed")
    }
}
