# Unread Message
When the customer service replies user's message, user can receive a notification of unread messages, even if the AIHelp page is not currently displayed.
You can implement this function either by proactively fetching or by third-party push.
WARNING
By default, AIHelp uses a randomly generated deviceId as userId to poll for the count of unread messages.
So, until you sync the correct userId to AIHelp, the unread message count may be inaccurate.
# By Fetching
# API
# fetchUnreadMessageCount / fetchUnreadTaskCount
Calling this method allows you to actively retrieve the unread message count for the current user.
[AIHelpSupportSDK fetchUnreadMessageCount];
[AIHelpSupportSDK fetchUnreadTaskCount];
You can call these APIs at any time to query the unread message count for the current user, but please note:
- This method has a frequency limit:
Repeated calls within the limit period will return the result of the previous query. During development, you can check the logs to see the time until the next valid call.
- This method will return 0 in the following situations to notify the caller that the current user has no unread messages:
- When the user has no ongoing complaints or tasks.
- After the user has opened the customer service conversation window, or checked all unread tasks.
# Event
Subscribe to the AIHelpEventMessageArrival
and AIHelpEventUnreadTaskCount
events to receive notifications about unread message changes for the current user.
void listener(const char *eventData, void (*acknowledge)(const char *ackData)) {
// `eventData`: { "eventType": 5, "msgCount": 1 }
// `eventData`: { "eventType": 8, "taskCount": 1 }
}
[AIHelpSupportSDK registerAsyncListener:listener eventType:AIHelpEventMessageArrival];
[AIHelpSupportSDK registerAsyncListener:listener eventType:AIHelpEventUnreadTaskCount];
# By Third-Party Push
Now we take APNs as an example to illustrate how the in-app notification works.
1、register APNs:
#import <UserNotifications/UserNotifications.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if (@available(iOS 10.0, *)) {
[[UNUserNotificationCenter currentNotificationCenter] requestAuthorizationWithOptions:UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
// The user has allowed push permissions
}
}];
} else {
UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
[[UIApplication sharedApplication] registerUserNotificationSettings:settings];
}
}
2、call the following method to inform AIHelp of the player's push token and push platform:
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 13) {
if (![deviceToken isKindOfClass:[NSData class]]) {
return;
}
const unsigned *tokenBytes = (const unsigned *)[deviceToken bytes];
NSString *strToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
token = strToken;
} else {
token = [NSString stringWithFormat:@"%@", deviceToken];
token = [token stringByReplacingOccurrencesOfString:@"<" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@">" withString:@""];
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
}
AIHelpUserConfigBuilder *userConfigBuider = [[AIHelpUserConfigBuilder alloc] init];
userConfigBuider.userId = @"userId";
[AIHelpSupportSDK updateUserInfo:userConfigBuider.build];
[AIHelpSupportSDK setPushToken:token pushPlatform:AIHelpTokenPlatformAPNS];
}
3、alert your users when you receive a new message from AIHelp:
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSDictionary *data = userInfo[@"data"];
if (data && [data[@"elva"] isEqualToString:@"yes"]) {
// alert your users that he/she has received a new message
}
}
4、AIHelp push data format is as follows:
{
"to":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification":{
"body":"This is your new message content",
"title":"customer service sends you a message.",
"sound":"Enabled",
"priority":"high",
"uid":"..."
},
"data":{
"body":"This is your new message content",
"title":"customer service sends you a message.",
"uid":"...",
"elva":"yes",
"entry_tag":"..."
}
}
