ios - 单击远程通知后能够重定向到指定 View Controller ，但只有 VC 但没有导航栏

Question

我在用户单击推送通知后设置了重定向，并且确实有效。但是，该应用程序重定向到 View Controller ，没有导航栏和底部工具栏。以下是我的重定向代码:-

// Did receive notification method here...

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo NS_AVAILABLE_IOS(3_0)
{
    NSLog(@"user info1 is %@",userInfo);


    [[NSNotificationCenter defaultCenter] postNotificationName:@"NOTIFICATION_RECIEVED"
                                                            object:nil
                                                          userInfo:nil];

    UIStoryboard *mainsboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UIViewController *vc = [mainsboard instantiateViewControllerWithIdentifier:@"notice"];
    [self.window.rootViewController presentViewController:vc animated:YES completion:nil];

我想我理解这个问题的意思是您希望 View Controller 出现在您在 Storyboard 中配置的导航 Controller 的上下文中。在这种情况下，您需要做更多的设置:

1. 在您的 Storyboard中找到包含带有“notice”ID 的导航 Controller ，并给它一个 Storyboard ID——可能类似于“noticeNavigationController”

2. 收到通知后，也从 Storyboard构建导航 Controller ，并使用您知道如何构建的“通知” View Controller 将其设置为根...

   // as you have it
   UIStoryboard *mainsboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
   UIViewController *vc = [mainsboard instantiateViewControllerWithIdentifier:@"notice"];
   
   // but now build a navigation controller, too
   UINavigationController *navVC = [mainsboard instantiateViewControllerWithIdentifier:@"noticeNavigationController"];
   // make your vc the root
   navVC.viewControllers = @[ vc ];
   
   // and present** that navigation controller
   [self.window.rootViewController presentViewController: navVC animated:YES completion:nil];
   

**请注意，除非您出于某种原因有意进行演示，否则更常见的做法是将应用的 rootViewController 设置为 navVC，而不是演示它。
