弹出并推送相同的视图不会调用viewWillAppear（）方法

Question

当我收到本地通知时，我会执行以下操作：

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notif {
    [navController popToRootViewControllerAnimated:NO];
    [navController pushViewController:notificationSplashViewController animated:YES];
}

如果我的notificationSplashViewController是当前的ViewController，则不会调用其viewWillAppear()方法。如何检测重新推送notificationSplashViewController？

尝试：

[notificationSplashViewController.view removeFromSuperview];
[navController popToRootViewControllerAnimated:NO];
[navController pushViewController:notificationSplashViewController animated:YES];

对我来说，这就行了。
