ios - 允许在超过 2 个 View 上导航

Question

所以我正在尝试创建一个 iphone 应用程序，并且正在尝试设置导航 Controller 。我让它从一个 View 工作到另一个 View 然后再返回。(下面的代码)有没有办法为多个 View 做到这一点？例如，从一开始就按下一个按钮切换到另一个 View ，然后按下另一个按钮转到另一个不同的 View 。我如何在不使用 Storyboard 和实际编程的情况下实现导航 Controller 工作？任何提示将不胜感激。

这是在 AppDelegate 中:

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.window.backgroundColor = [UIColor whiteColor];
    LoginViewController *loginController = [[LoginViewController alloc] init];
    UINavigationController *navController = [[UINavigationController alloc]     initWithRootViewController:loginController];
    self.window.rootViewController = navController;
    [self.window makeKeyAndVisible];
    return YES;

这是其中一个 View 中的按钮方法之一:

[self.navigationController pushViewController:mainViewController animated:YES];

Answer 1

这就是导航 Controller 的作用。

您可以像这样导航到多个 View ；

To navigate from main view to secondViewController

[self.navigationController pushViewController:secondViewController animated:YES];

当前的导航栈是mainViewcontroller -> secondViewController

From second View to third View

[self.navigationController pushViewController:thirdViewController animated:YES];

当前的导航栈是mainViewcontroller -> secondViewController ->thirdViewController

To go back to previous view you can call

 [self popViewControllerAnimated:YES];
