接收远程推送通知时，打开视图控制器 [英] Open view controller when receiving remote Push Notification

问题描述

我用故事板，我想，当用户收到远程推送通知，要始终打开相同的观点，即使该应用程序在后台或打开。我需要present的看法是在故事板设定初始视图控制器后，四点看法。我读这帖子：

I'm using storyboard , and I want to open always the same view when user receives remote push notifications, even the app is in background or opened. The view I need to present is four views after the initial view controller set in the storyboard. I read this posts:

<一个href=\"http://stackoverflow.com/questions/10430860/how-can-i-show-a-modal-view-in-response-to-a-notification-as-a-new-window-no-p\">How我可以显示在响应通知作为一个新的窗口，一个模式的看法？ （无父VC）

<一个href=\"http://stackoverflow.com/questions/6734338/open-a-specific-tab-view-when-user-receives-a-push-notification\">Open一个特定的选项卡/视图时，用户会收到一个推送通知

因此​​，这里是我的code：

So here is my code:

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

    UINavigationController *navController = (UINavigationController *)self.window.rootViewController;
    notificacionViewController *menu = [navController.storyboard instantiateViewControllerWithIdentifier:@"notificacion"];

    // First item in array is bottom of stack, last item is top.
    navController.viewControllers = [NSArray arrayWithObjects:menu,nil];

    [self.window makeKeyAndVisible];


}

但是，当我收到通知，应用程序与此错误崩溃：

But when I receive notification, the app crashes with this error:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[locationViewController setViewControllers:]: unrecognized selector sent to instance 0x42ccd0'

locationViewController是在故事板设置为初始视图控制器。

locationViewController is the view controller set as initial in the storyboard.

非常感谢。

推荐答案

请尝试以下code：

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
    UINavigationController *navController = (UINavigationController *)self.window.rootViewController;
    NotificationViewController *notificationViewController = [[NotificationViewController alloc] init];
    [navController.visibleViewController.navigationController pushViewController:notificationViewController];    
}
