## 介紹
關於UIWindow、UINavigationController和UITabBarController我把他們都理解成一個容器，並不用於真正顯示內容，它們之前可以嵌套比如這樣：：
UIWindow > UITabBarController > UINavigationController > UIViewController真正顯示內容的是UIViewController

1. UIWindow 如果是一個Chrome瀏覽器的窗口，那麼其他幾個可以這樣理解
2. UITabBarController 是Chrome的Tab欄
3. UINavigationController 是Chrome的歷史記錄功能
4. UIViewController 是Chrome顯示網頁區域

一個Chrome窗口可以有多個Tab, Tab下只有一個顯示網頁的區域，因為保存有歷史記錄，所以可以在之前打開的頁面間切換

## 1.m
- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    if ([self.navigationController.viewControllers indexOfObject:self] == NSNotFound) {
        // back button was pressed.  We know this is true because self is no longer in the navigation stack.
        NSLog(@"[self.navigationController.viewControllers indexOfObject:self] == NSNotFound");
    }
}
