弹出和推送同一视图不会调用 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 ViewController，则不会调用其 viewWillAppear() 方法。如何检测 notificationSplashViewController 的重新推送？

尝试一下：

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

对我来说，这成功了。
