Ios '；NSInvalidArgumentException'；关于UILocalNotification加载

从本地通知加载应用程序时，我试图读取其有效负载。为此，我有以下代码：

AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    //Loading Stuff

    UILocalNotification *localNotif =
    [launchOptions objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
    if (localNotif) {
        UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];
        [(UITabBarController *)self.window.rootViewController setSelectedIndex:1];
        UINavigationController *nav = [[(UITabBarController *)self.window.rootViewController viewControllers] objectAtIndex:1];
        IMTRewardsViewController *rvc = [storyboard instantiateViewControllerWithIdentifier:@"rewardsView"];
        [rvc loadPushNotification:localNotif];
        [nav pushViewController:rvc animated:NO];

    }

    return YES;
}

IMTRewardsController.h：

-(NSDictionary *)loadPushNotification:(UILocalNotification *)notification;

IMTRewardsController.m：

- (NSDictionary *)loadPushNotification:(UILocalNotification *)notification
{
    NSLog(@"%@",notification.userInfo);
    return notification.userInfo;
}

从本地通知加载应用程序时，我收到以下错误：

<Error>: -[UIViewController loadPushNotification]: unrecognized selector sent to instance 0x14e70b30
<Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIViewController loadPushNotification]: unrecognized selector sent to instance 0x14e70b30'

：-[UIViewController loadPushNotification]：无法识别的选择器已发送到实例0x14e70b30
：***由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“-[UIViewController loadPushNotification]：未识别的选择器已发送到实例0x14e70b30”

您知道如何解决此问题并防止将来出现此问题吗？

此错误表明您撤回的视图控制器只是一个UIViewController，而不是您期望的IMTRewardsViewController。您确定在情节提要中将自定义类属性设置为该类型吗？

您可能需要先对其进行强制转换。情节提要返回UIViewController

IMTRewardsViewController *rvc = (IMTRewardsViewController *)[storyboard instantiateViewControllerWithIdentifier:@"rewardsView"];

a的儿子！这正是问题所在。谢谢，先生，没问题。这几乎每次都发生在我身上。
