Ios 将UIViewcontroller推送到UINavigation控制器

我有登录屏幕和忘记密码屏幕。忘记密码屏幕连接到导航控制器，但我的登录屏幕未连接到导航控制器，因此如何将登录屏幕移动到忘记屏幕

这是我的密码

forgotpasswod *secondViewController =
    [self.storyboard instantiateViewControllerWithIdentifier:@"forgotpasswodpage"];

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

---

您可以显示视图控制器

let vc : ForgotPassword = storyboard.instantiateViewControllerWithIdentifier("forgotView") as  ForgotPassword

let navigationController = UINavigationController(rootViewController: vc)

self.presentViewController(navigationController, animated: true, completion: nil)

对于obj c

 ForgotPassword *secondViewController =
[self.storyboard instantiateViewControllerWithIdentifier:@"forgotpasswodpage"];

UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:secondViewController];
[self presentViewController:controller animated:YES completion:nil];

let vc : ForgotPassword = storyboard.instantiateViewControllerWithIdentifier("forgotView") as  ForgotPassword

let navigationController = UINavigationController(rootViewController: vc)

self.presentViewController(navigationController, animated: true, completion: nil)

对于obj c

 ForgotPassword *secondViewController =
[self.storyboard instantiateViewControllerWithIdentifier:@"forgotpasswodpage"];

UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:secondViewController];
[self presentViewController:controller animated:YES completion:nil];

如果要将ViewController移动到导航ViewController，请使用presentView控制器

将此代码粘贴到操作方法中

- (IBAction)forgotpassword:(id)sender {

    forgotpasswod *secondViewController =
    [self.storyboard instantiateViewControllerWithIdentifier:@"forgotpasswodpage"];

    UINavigationController *controller = [[UINavigationController alloc] initWithRootViewController:secondViewController];
    [self presentViewController:controller animated:YES completion:nil];
}

当您尝试此代码时，还可以更改导航栏的颜色

if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) {
        // iOS 6.1 or earlier
        self.navigationController.navigationBar.tintColor = [UIColor colorWithHexString:@"#37B578"];
    } else {
        // iOS 7.0 or later
        self.navigationController.navigationBar.barTintColor = [UIColor colorWithHexString:@"#37B578"];
        self.navigationController.navigationBar.translucent = NO;
    }

if（floor（NSFoundationVersionNumber）这里的问题是导航控制器为零，因为初始控制器（LoginViewController）不像forgorpassordViewController那样嵌入到导航控制器中

为什么不将LoginViewController嵌入到navigationController中，并将ForgotViewController上的标识符设置为“forgotpasswodpage”，就像您所做的那样

然后，您完全按照代码中的内容进行操作

forgotpasswod *secondViewController =
    (forgotpasswod *)[self.storyboard instantiateViewControllerWithIdentifier:@"forgotpasswodpage"];

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

另外，我更希望您使用[self.navigationController showViewController:secondViewController动画：是]；

单击忘记密码，只需从故事板将导航控制器设置为应用程序窗口的rootview控制器。它将自动加载连接到导航控制器的视图。
