【问题描述】：

我在我的项目中使用SWRevealViewController，我想在应用收到通知时打开一个特定的控制器。我尝试了很多解决方案，但没有任何效果。

如何从我的 AppDelegate 中显示特定的 ViewController？

(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {

    UIApplicationState appState = UIApplicationStateActive;
    if ([application respondsToSelector:@selector(applicationState)]) {
        appState = application.applicationState;
    }
    application.applicationIconBadgeNumber = 0;
    if (appState != UIApplicationStateActive) {

        SWRevealViewController *navigationController = (SWRevealViewController *)self.window.rootViewController;
        UINavigationController *nav = (UINavigationController *)navigationController;
        UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
        PushNotificationsVC *controller = (PushNotificationsVC*)[mainStoryboard instantiateViewControllerWithIdentifier: @"PushNotificationsVC"];
        [nav pushViewController:controller animated:YES];

    } else {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Notification"
                                                            message:[NSString stringWithFormat:@"%@",[[userInfo objectForKey:@"aps"] valueForKey:@"alert"]]
                                                           delegate:nil
                                                  cancelButtonTitle:@"OK"
                                                  otherButtonTitles:nil];
        [alertView show];
    }
}

【问题讨论】：

您应该阅读FAQ 来提出好的问题。
我的项目中有一个幻灯片菜单，因为我使用了 SWRevealViewController 组件。当我收到推送通知时，我想打开一个特定的屏幕（ViewController）。我无法从 appdelegate 中打开特定的控制器。（applicationDidReceiveNotification）。你明白我想说的吗？？
如果您有任何想法，请回复
你试过这个吗：[self.window.rootViewController presentViewController:MyCustomViewController animated:NO completion:nil]？你能告诉我们你在-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo;有什么吗？

那些寻求快速答案的人：

    var storyboard = UIStoryboard(name: "Main", bundle: nil)

    var destinationController = storyboard.instantiateViewControllerWithIdentifier("DestinationController") as? DestinationController

    var frontNavigationController = UINavigationController(rootViewController: destinationController!)

    var rearViewController = storyboard.instantiateViewControllerWithIdentifier("MenuController") as? MenuController

    var mainRevealController = SWRevealViewController()

    mainRevealController.rearViewController = rearViewController
    mainRevealController.frontViewController = frontNavigationController
    self.window!.rootViewController = mainRevealController
    self.window?.makeKeyAndVisible()

对于那些使用故事板关注http://www.appcoda.com/ios-programming-sidebar-navigation-menu/的人。

UIStoryboard *st = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
DestinationController *descController = (DestinationController*)[st instantiateViewControllerWithIdentifier: @"storyboardID_DestController"];
UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:descController];
SidebarViewController *rearViewController = (SidebarViewController*)[st instantiateViewControllerWithIdentifier: @"storyboardID_SidebarMenu"];

RevealViewController *mainRevealController = [[SWRevealViewController alloc]  init];

mainRevealController.rearViewController = rearViewController;
mainRevealController.frontViewController= frontNavigationController;

self.window.rootViewController = mainRevealController;

希望它可以帮助其他人......

这对我有用，但隐藏了我的后退按钮，因为我正在导航到子菜单视图控制器

【解决方案3】：

正如user34336439提到的一些单词缺陷，正确答案是

    FrontViewController *frontViewController = [[LiveScoreViewController alloc] init];
    RearViewController *rearViewController = [[RearViewController alloc] init];

    UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:frontViewController];
    UINavigationController *rearNavigationController = [[UINavigationController alloc] initWithRootViewController:rearViewController];
    SWRevealViewController *mainRevealController = [[SWRevealViewController alloc] initWithRearViewController:rearNavigationController frontViewController:frontNavigationController];

    self.window.rootViewController = mainRevealController;

【讨论】：

【解决方案4】：

SWRevealViewController *navigationController = (SWRevealViewController *)self.window.rootViewController;
UINavigationController *nav = (UINavigationController *)navigationController;

修改------

UINavigationController *nav = (UINavigationController *)navigationController.frontViewController;



UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
PushNotificationsVC *controller = (PushNotificationsVC*)[mainStoryboard instantiateViewControllerWithIdentifier: @"PushNotificationsVC"];
[nav pushViewController:controller animated:YES];

【讨论】：

NavigationViewController *frontNavigationController = [NavigationViewController alloc] initWithRootViewController:frontVC]; NavigationViewController *rearNavigationController = [[NavigationViewController alloc] initWithRootViewController:rearVC]; SWRevealViewController *mainRevealController = [[SWRevealViewController alloc] initWithRearViewController:rearNavigationController frontViewController:frontNavigationController];我找到了解决方案感谢大家的付出。抱歉，我无法投票给任何人。
