Hi,

I have read this documentation https://quickblox.com/developers/IOS for implement Group chat

When I am create chat Dialog, response of the QBRequest createDialog return null

I’m using below source code to create chatDialog,Please check the code and help me.

Source Code :

QBChatDialog *chatDialog [[QBChatDialog alloc] initWithDialogID:NULL type:QBChatDialogTypeGroup];chatDialog.name Chat with User A, User B, User C chatDialog.occupantIDs [ (48636831), (48660982), (48637053)];[QBRequest createDialog:chatDialog successBlock:^(QBResponse *response, QBChatDialog *createdDialog) {NSlog( “result % ”,chatDialog); // return null for (NSString *occupantID in chatDialog.occupantIDs) { QBChatMessage *inviteMessage [self createChatNotificationForGroupChatCreation:chatDialog]; NSTimeInterval timestamp (unsigned long)[[NSDate date] timeIntervalSince1970];

// customParams[ date_sent ] (timestamp);

 inviteMessage.recipientID [occupantID integerValue]; [[QBChat instance] sendSystemMessage:inviteMessage completion:^(NSError * _Nullable error) { NSLog( inviteMessage % ,inviteMessage);} errorBlock:^(QBResponse *response) { NSLog( ERROR % ,[response.error description]);

Response :
