Hello, @williamtran1988 We can't help you until you specify:

1. SDK Version.
2. Logs .
3. Code snippet for creating subscriptions.

[williamtran1988]

I am using Quickblox iOS SDK version 2.7.3.

and my script:

NSString *deviceUDID = [info objectForKey:@"deviceUDID"];
NSData *deviceTokenData = [[NSUserDefaults standardUserDefaults]   
    objectForKey:@"deviceTokenData"];

QBMSubscription *subscription = [QBMSubscription subscription];
subscription.notificationChannel = QBMNotificationChannelAPNS;
subscription.deviceUDID = deviceUDID;
subscription.deviceToken = deviceTokenData;

[QBRequest createSubscription:subscription successBlock:^(QBResponse *response, NSArray *objects) {

} errorBlock:^(QBResponse *response) {

}];

I always get success. But Device is registered with other User. I have tried to delete current subscription on my device. Then tried to create new subscription with new User account with this device. But it returned back to first User account. It's strange.

Hi everybody,

We are starting to use Quickblox for our application with calling and push notification features. But we have an issues on the push notification. I don't that is the rule of quickblox or an known issues.

I knew that. 1 user can subscribe on multi devices.

My cases here:

I already logged with a user U1 on device D and checked on the admin page on the Subscriptions page and I see a UUID of Device A.

But when I logout the user U1 on device D and try to login with a new user U2 on device D.

• Case 1: I don't see the UUID of device D mapping with user U2
• Case 2: I tried to unregister or delete the subscription on admin page or by API BEFORE login with user U2. I see. It is successful. But when we go to admin page. I see the UUID of device D mapping with the user U1 again ( It means, the user U1 appear again on the subscription page with UUID of device D)

My question is: How can I can delete a subscription was exists with a user and register to a new user (I mean, multi users can login and subscribe on a device. I understand we must unregister the old user on the subscription)?

I am looking forward for your response!

Thanks and Best regards, Jason

@phamminhvu Hello, you should use method:

    NSString *deviceIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    [QBRequest unregisterSubscriptionForUniqueDeviceIdentifier:deviceIdentifier successBlock:^(QBResponse *response) {
        //
    } errorBlock:^(QBError *error) {
        //
    }];

@VitaliyGuru Thanks for you support. It could help me so much. But I have a case:

• If 2 quickblox's user (User 1 and User 2) logged on 1 device. When I try to logout User 1 and relogin with User 2. It always show the Subscription User 1. I already unregister Subscription with UUID for USER 1 before register create subscription for User 2

It this case we have the same Device UUID and device Token but difference User

Thanks, Jason

@phamminhvu Have you try these steps in our sample chat?

[phamminhvu]

@VitaliyGuru Yes, there are our steps: Step 1: Login to QB: [[ChatManager instance] logInWithUser:user completion:^(BOOL error) { //code }]

Step 2. Unregister the current device UUID on subscription

[QBRequest unregisterSubscriptionForUniqueDeviceIdentifier:]

Step 3. If unregister is successful then create subscription [QBRequest createSubscription:subscription successBlock:^(QBResponse response, NSArray objects) { //code }]

Step 4. User 1 logout: if([ChatManager.instance isLoggedIn]){ [ChatManager.instance logOut]; }

User2 will be login with the same steps above

Hi @phamminhvu, Any updates?

[phamminhvu]

Still can not update device UUID. @VitaliyGuru: any suggestion for us!

[ghost]

@phamminhvu please provide logs for you case:

If 2 quickblox's user (User 1 and User 2) logged on 1 device. When I try to logout User 1 and relogin with User 2. It always show the Subscription User 1. I already unregister Subscription with UUID for USER 1 before register create subscription for User 2

[williamtran1988]

Any updates? The problem still appear in latest version 3.0.

We DID unregisterSubscriptionForUniqueDeviceIdentifier when User logged out. Then login with other USer (User2). But subscription is always User1.

Do you have any ideas?

Hi @williamtran1988,

It may be because of these 2 lines:

NSString *deviceUDID = [info objectForKey:@"deviceUDID"];
NSData *deviceTokenData = [[NSUserDefaults standardUserDefaults]   
objectForKey:@"deviceTokenData"];

As Apple wrote, you should not cache deviceToken, it's prohibited

The right way to subscribe is:

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken
{
    NSString *deviceIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

    QBMSubscription *subscription = [QBMSubscription subscription];
    subscription.notificationChannel = QBMNotificationChannelAPNS;
    subscription.deviceUDID = deviceIdentifier;
    subscription.deviceToken = deviceToken;

    [QBRequest createSubscription:subscription successBlock:^(QBResponse *response, NSArray *objects) {

    } errorBlock:^(QBResponse *response) {

    }];
}

could you make sure that you have the same in your app?

[williamtran1988]

Yes, we are using this device id too: NSString *deviceIdentifier = [[[UIDevice currentDevice] identifierForVendor] UUIDString];

But the problem still the same.

Finally, i found out the what is it now. If you did not delete user when you logged out from application, You will not create a new subscription for new user in 1 device.

[soulfly]

But what about this line?

NSData *deviceTokenData = [[NSUserDefaults standardUserDefaults]   
objectForKey:@"deviceTokenData"];

[williamtran1988]

Which one is device token which i received from:

• (void) application:(UIApplication)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData)deviceToken

Delete user and create new subscript for new user could be a solution. But do you know why i could not use this method:

deleteUserWithID:successBlock:errorBlock:

Which i referred from : https://sdk.quickblox.com/ios/documentation/Classes/QBRequest.html#//api/name/deleteUserWithID:successBlock:errorBlock:

@williamtran1988 were you able to fix this?

Closing due to lack of the response from issue creator. If the issue is still there for you, I recommend you to create a new issue. As this is not reproducible in any of our sample nor in our app Q-municate, I recommend you to attach some sample project with issue been reproducible next time.
