ios - iOS，先强制退出应用程序，点击接收通知横幅后，应用程序启动失败

Question

我使用APNs将通知发送到我的应用程序。但是，当我执行以下步骤时，我的应用程序无法正常运行:

脚步

滑动应用以强制退出(应用未运行，不在后台模式下..)

从APN发送通知

在我的iPhone上收到了通知，然后我轻按了通知横幅

应用程序似乎尝试启动(显示启动图像)，但是启动失败(崩溃？)

我的应用程序可以接收通知的前台和后台。
点按背景中的通知横幅，然后它可以将应用程序置于前台，然后转到我编写的 View ，一切正常。

除了强制退出外，APP

这是我在AppDelegate.m中的代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
MFSideMenuContainerViewController *container = [MFSideMenuContainerViewController
                                                    containerWithCenterViewController:[self navigationController]

    self.window.rootViewController = container;
    [self.window makeKeyAndVisible];

    UIMutableUserNotificationAction *acceptAction =
    [[UIMutableUserNotificationAction alloc] init];

    // Define an ID string to be passed back to your app when you handle the action
    acceptAction.identifier = @"MARK_AS_READ_IDENTIFIER";

    // Localized string displayed in the action button
    acceptAction.title = NSLocalizedString(@"Mark as Read", nil);

    // If you need to show UI, choose foreground
    acceptAction.activationMode = UIUserNotificationActivationModeBackground;

    // Destructive actions display in red
    acceptAction.destructive = NO;

    // Set whether the action requires the user to authenticate
    acceptAction.authenticationRequired = NO;

    // Add the actions to the category and set the action context
    [inviteCategory setActions:@[acceptAction]
                    forContext:UIUserNotificationActionContextDefault];

            // go to notification view
        // because will go to the notification view detail, set status to read
            [self gotoNotificationView:userInfo]; //uniqueID
            break;
        default:
            break;
    }

    // Set icon badge number to zero
    application.applicationIconBadgeNumber = 0;

    // Handle the received message
    // Invoke the completion handler passing the appropriate UIBackgroundFetchResult value
    handler(UIBackgroundFetchResultNoData);

    // send post notification for updating the badge, will get the notification in foreground
    [[NSNotificationCenter defaultCenter] postNotificationName:@"APNsNotification" object:self userInfo:nil];

}

有人以前有这个问题吗？我错过了什么？

请帮我!!

您可以发出警报并检查launchOptions

if (launchOptions) {
    if ([launchOptions objectForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"]) {
        [self application:self didReceiveRemoteNotification:[launchOptions objectForKey:@"UIApplicationLaunchOptionsRemoteNotificationKey"] fetchCompletionHandler:^(UIBackgroundFetchResult result) {

        }];
    }

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)newUserInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {

if ([[UIApplication sharedApplication] applicationState] == UIApplicationStateActive) {
NSString *str = [[userInfo objectForKey:@"aps"] objectForKey:@"alert"];
}
}
