本文介绍如何在iOS应用中使用导航控制器添加新的视图控制器，并配置了取消和完成按钮。具体步骤包括创建RecipeAddViewController实例并设置其代理，然后通过UINavigationController呈现新的视图控制器。

<span style="font-size:18px;">- (void)add:(id)sender {
   // Create the root view controller for the navigation controller
   // The new view controller configures a Cancel and Done button for the
   // navigation bar.
   RecipeAddViewController *addController = [[RecipeAddViewController alloc]
init];
   // Configure the RecipeAddViewController. In this case, it reports any
   // changes to a custom delegate object.
   addController.delegate = self;
   // Create the navigation controller and present it.
   UINavigationController *navigationController = [[UINavigationController alloc]
initWithRootViewController:addController];
[self presentViewController:navigationController animated:YES completion: nil];
}</span>
