收到推送通知时打开特定的视图控制器？答案

【问题描述】：

我会通过打开 parse.Using IOS 8 发送的推送通知来设置打开我们特定视图。我怎样才能做到这一点？？我使用了这段代码：

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

}

【解决方案1】：

我用这个代码

- (UIViewController*)topViewController {
    return [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
}


- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController {

    if ([rootViewController isKindOfClass:[UITabBarController class]]) {
        UITabBarController* tabBarController = (UITabBarController*)rootViewController;
        return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
    } else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
        UINavigationController* navigationController = (UINavigationController*)rootViewController;
        return [self topViewControllerWithRootViewController:navigationController.visibleViewController];
    } else if (rootViewController.presentedViewController) {
        UIViewController* presentedViewController = rootViewController.presentedViewController;
        return [self topViewControllerWithRootViewController:presentedViewController];
    } else {
        return rootViewController;
    }
}

这样称呼：

- (void) doSomething {
    UIViewController *topViewController = [self topViewController];
    NotificationViewController *notificationViewController = [[NotificationViewController alloc] init];
    [topViewController.navigationController pushViewController:notificationViewController animated:YES];
}

不要忘记在你的应用程序中添加此代码：didFinishLaunchingWithOptions:（当用户在应用程序关闭的情况下触摸通知时）

    NSDictionary *remoteNotification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (!remoteNotification) {
    UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (notification) {
        [self doSomething];
    }
} else {
    [self doSomething];
}

【讨论】：

我这样做了，但它仍然不起作用；我编辑了这段代码： - (void) doSomething { UIViewController *topViewController = [self topViewController]; Mappa *notificationViewController = [[Mappa alloc] init]; [topViewController.navigationController pushViewController:notificationViewController 动画：YES]; }
究竟是什么不工作？你在 application:didReceiveRemoteNotification: 中调用了 doSomething: 对吗？
我在 didReciveRemoteNotification 中调用了 doSomething 但它不起作用。当我从推送通知打开应用程序时，它会继续在 mainView 中打开。在 doSomething 中将 myViewController 替换为 notificationViewController 是否正确？
如果您的应用已关闭，您需要使用我回复中的最后一个代码。
