【问题描述】：

我在我的项目中使用quickblox ios的​​聊天API，聊天应用程序，现在一切正常...当用户在线时，或者应用程序未从后台删除他正在推送聊天页面中的通知和消息.. 但是当应用程序从后台删除时，他收到推送通知，但消息没有出现在聊天页面中，它只出现在推送通知中......我将我的问题发送给 quickblox 支持，他们给了我一个代码来替换我的项目，现在我的问题代码在这里：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:  (NSDictionary *)launchOptions 
    // Override point for customization after application launch.
    cManager = [ConnectionManager sharedMannager];
    [cManager sendNetworkIdUpdate:[[DataManager sharedCenter]currentnetworkIdentifier]];

    [QBSettings setApplicationID:-----];
    [QBSettings setAuthorizationKey:@"--------"];
    [QBSettings setAuthorizationSecret:@"--------"];
    [QBSettings setAccountKey:@"--------"];

    [cManager getBlockedList];

    if (launchOptions != nil) 
        NSLog(@"Launched from push notification");
        NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
        NSLog(@"%@",launchOptions);
        [[DataManager sharedCenter]setPushData:[notification valueForKeyPath:@"aps.user_info"]];
        // Do something with the notification dictionary

    

    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
    return YES;


- (void)applicationWillResignActive:(UIApplication *)application
    if ([[[DataManager sharedCenter]currentUser]userChatId])
        [QBUsers logOutWithDelegate:[ChatService instance]];
    


- (void)applicationWillEnterForeground:(UIApplication *)application

    if ([[DataManager sharedCenter]chat_user] != nil) 
        [[QBChat instance] loginWithUser:[[DataManager sharedCenter]chat_user]];
    


- (void)applicationDidEnterBackground:(UIApplication *)application

    BOOL isLoggedIntoChat = [[QBChat instance] isLoggedIn];

    if (isLoggedIntoChat) 
        [[QBChat instance] logout];
    


- (void)applicationDidBecomeActive:(UIApplication *)application
    if ([[UIApplication sharedApplication]applicationIconBadgeNumber]>0)
        [UIApplication sharedApplication].applicationIconBadgeNumber=0;
        [cManager clearBadge];
    

    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.


- (void)applicationWillTerminate:(UIApplication *)application
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
    /*if ([[[DataManager sharedCenter]currentUser]userChatId])
     [QBUsers logOutWithDelegate:[ChatService instance]];
     */

    if ([[LocalStorageService shared]messagesHistory] && [[[DataManager sharedCenter]currentUser]userId])
        NSData *data = [NSKeyedArchiver archivedDataWithRootObject:[[LocalStorageService shared]messagesHistory]];
        [[[DataManager sharedCenter]defaults]setObject:data forKey:[NSString stringWithFormat:@"%@%@",[[[DataManager sharedCenter]currentUser]userId],kMessageHistoryBlock]];
        [[[DataManager sharedCenter]defaults]synchronize];
    


- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
    NSString* devToken = [[[[deviceToken description]
                            stringByReplacingOccurrencesOfString:@"<"withString:@""]
                           stringByReplacingOccurrencesOfString:@">" withString:@""]
                          stringByReplacingOccurrencesOfString: @" " withString: @""];
    NSLog(@"Update Token: %@",devToken);

    [cManager sendPushTokenUpdate:devToken];


- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
    NSLog(@"Opend from push notification");
    NSLog(@"%@",userInfo);

    UIApplicationState state = [[UIApplication sharedApplication]applicationState];
    if (state != UIApplicationStateActive)

        if ([userInfo valueForKeyPath:@"aps.user_info"])
            [[DataManager sharedCenter]setPushData:[userInfo valueForKeyPath:@"aps.user_info"]];
            [[NSNotificationCenter defaultCenter]postNotificationName:kShowPush  object:nil];

        

    

    [[NSNotificationCenter defaultCenter]postNotificationName:kUpdateTables object:nil];
    [cManager clearBadge];

问题依旧出现！ ，有什么帮助吗？

【问题讨论】：

通知 kUpdateTables 有什么作用？您在 applicationDidReceiveRemoteNotification 中的代码在哪里更新应该在聊天中显示的内容？

您好，根据好友请求更新用户表。问题是如果应用程序被终止（完全关闭），应用程序不会收到来自 QuickBlox 的离线消息。

@LenaBru 嗨，它是根据好友请求更新用户表。问题是如果应用程序被终止（完全关闭），应用程序不会收到来自 QuickBlox 的离线消息

你能改变方法 application:didReceiveRemoteNotification: with - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler NS_AVAILABLE_IOS (7_0);另一种选择是，在您的应用程序 WillEnterForeground 中，您可以下载最近的活动

【参考方案1】：

您必须正确退出聊天。服务器应该确定您的用户处于离线状态

首先，参考Chat in background mode文档http://quickblox.com/developers/SimpleSample-chat_users-ios#Chat_in_background_mode

尝试在 applicationWillTerminate 和 applicationDidEnterBackground 中退出聊天：

- (void)applicationWillTerminate:(UIApplication *)application

    [[QBChat instance] logout];


- (void)applicationDidEnterBackground:(UIApplication *)application

    [[QBChat instance] logout];

【讨论】：

嗨，我做了更改，但没有用！我在哪里可以给你发源来帮我检查？或者如果你想要钱

您在这些消息中设置了正文还是为空？请发布您的代码如何发送消息

看......我很困惑......我可以给你发一个源来检查我的代码吗？我在这里：facebook.com/m3lawe

@IgorKhomenko 我也面临同样的问题。我在应用程序处于后台时注销并在“applicationWillEnterForeground”中再次登录，但我没有收到离线消息。你能帮帮我吗？
