Question

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

步骤

滑动应用以强制退出（应用未运行，不在后台模式..）
从APN发送通知
在我的iPhone上收到通知，我点了通知横幅
app似乎尝试启动（显示启动图像），但启动失败（崩溃？）

我的应用可以接收通知前景和背景。点击背景中的通知横幅然后它可以将应用程序带到前台然后转到我写的视图，一切正常。

强制退出 APP

这是我在AppDelegate.m中的代码

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

    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;

    // First create the category
    UIMutableUserNotificationCategory *inviteCategory =
    [[UIMutableUserNotificationCategory alloc] init];

    // Identifier to include in your push payload and local notification
    inviteCategory.identifier = @"actionCategory";

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

    // Set the actions to present in a minimal context
    [inviteCategory setActions:@[acceptAction]
                    forContext:UIUserNotificationActionContextMinimal];
    NSSet *categories = [NSSet setWithObject:inviteCategory];
    [[UIApplication sharedApplication] registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeSound | UIUserNotificationTypeBadge | UIUserNotificationTypeAlert) categories:categories]];

    // for calling didReceiveRemoteNotification when app first launch
    if (launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]) {
        [self application:application didReceiveRemoteNotification:launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey]];
    }
    return YES;
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
    //register to receive notifications
    [application registerForRemoteNotifications];
}

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
        NSLog(@"Device token: %@",deviceToken);
}

- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Fail to get device token: %@", error);
}

// tap the backgraund banner button
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)newUserInfo completionHandler:(void (^)())completionHandler {
    if ([identifier isEqualToString:@"MARK_AS_READ_IDENTIFIER"]) {
        // when tapping the background banner's button will mark the notification status to read
        [Functions updateComingNotificationToRead];
    }

    if (completionHandler) {
        completionHandler();
    }
}

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)newUserInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))handler {
   //NSLog(@"Notification received: %@ %@", newUserInfo,[newUserInfo objectForKey:@"aps"] );
    userInfo = newUserInfo;

    NSString *alertMessage = [[newUserInfo objectForKey:@"aps"]  objectForKey:@"alert"];
    UIApplicationState state = [application applicationState];
    UIAlertView *alertView = nil;

    // for background banner use
    switch (state) {
        case UIApplicationStateActive: // when app is alive, show alert to notify user
            alertView =  [[UIAlertView alloc]initWithTitle:NSLocalizedString(@"SmartHome",nil) message:NSLocalizedString(alertMessage,nil) delegate:self cancelButtonTitle:NSLocalizedString(@"Close",nil) otherButtonTitles:NSLocalizedString(@"Open",nil),NSLocalizedString(@"Mark as Read",nil), nil];
            [alertView show];
            break;
        case UIApplicationStateBackground: // app is in background mode
            // user tap the banner or tap the mark as read button, code will go here
            [Functions addNotificationDataInDatabase:[newUserInfo objectForKey:@"uniqueID"] type:[newUserInfo objectForKey:@"deviceType"] event:[newUserInfo objectForKey:@"event"] time:[newUserInfo objectForKey:@"time"] read:@"0" description:alertMessage];
            break;
        case UIApplicationStateInactive: // tapping the banner
            //NSLog(@"UIApplicationStateInactive");
            // 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];

}

以前有人有这个问题吗？我错过了什么吗？

请帮助我!!

你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"];
}
}

iOS，强制退出应用程序，点击接收通知横幅后，应用启动失败
