将导航栏滑开，就像 iPhone 的照片查看器一样

有人可以解释一下，如何在 tableviewcontroller 中滑动导航栏，就像 iphone 照片查看器的导航栏一样吗？

如果有人能给我一些代码，那就太好了。

感谢和问候马可

您需要使用 UINavigationController，然后此功能几乎是“免费”的。
在创建阶段，您首先创建视图控制器。然后创建一个 UINavigationController，并将其传递给您之前创建的视图控制器。
稍后，当您想要滑开导航栏时，您可以使用 pushViewController:animated: 函数调用推送一个新的视图控制器。看一下下面的代码：

// Creation time
// Create your own view controller. below is just an example
UIViewController *myController = [[UIViewController alloc] init];

// Now create a navigation controller
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myController];

// Retain the above somehow, add their view to the Window etc. - not detailed here

// Later, when you want to slide away your controller, you need to push a new view controller. 
// The below code assumes "self" is actually myController which you defined previously:

UIViewController *newController = [[UIViewController alloc] init];
[self.navigationController pushViewController:newController animated:YES];
// The above line will make the controller and navigation bar slide away, revealing your new controller

这是一个非常粗略的代码示例，其中不包括内存管理等所有细节。我希望这就是您正在寻找的内容。

You need to use a UINavigationController, and then this functionality comes almost "for free".
At creation stage, you first create your view controller. Then you create a UINavigationController, passing it your previously created view controller.
Later on, when you want to slide away the navigation bar, you push a new view controller using the pushViewController:animated: function call. Take a look at the code below:

// Creation time
// Create your own view controller. below is just an example
UIViewController *myController = [[UIViewController alloc] init];

// Now create a navigation controller
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:myController];

// Retain the above somehow, add their view to the Window etc. - not detailed here

// Later, when you want to slide away your controller, you need to push a new view controller. 
// The below code assumes "self" is actually myController which you defined previously:

UIViewController *newController = [[UIViewController alloc] init];
[self.navigationController pushViewController:newController animated:YES];
// The above line will make the controller and navigation bar slide away, revealing your new controller

This is a very rough code sample, which does not include all the details such as memory management etc. I hope this is what you were looking for.
