Twilio - Inviting Users on a private channel by inviteByIdentity using swift client code

Question

if the channel does not exist then we create the new private channel

let options: [NSObject:AnyObject] = [
TWMChannelOptionFriendlyName: defaultChannel,
TWMChannelOptionUniqueName: defaultChannel,
TWMChannelOptionType: TWMChannelType.Private.rawValue
]  

channels?.createChannelWithOptions(options, completion: { (result, 
channel) in
    if result.isSuccessful(){
        channel.joinWithCompletion({ (result) in
            if result.isSuccessful(){ ... }})

Once, the user joins the channel successfully, we send invite to the other user to join the same channel.

availableChannel.members.inviteByIdentity(other_user_name, completion: 
{ 
(result) in
    if result.isSuccessful(){ ... })

But for other user how can he get notify when other user send him chat invitation, in sample app of twilio chat i am not getting any response for invitation accept.

Answer 1

When user created new channel , then all other users who have registered in the same app get notify via the delegate methods that new channel is created.

So, simple solution is create channel name using sender_receiver name, so when receiver called the delegate methods he will check whether its name is present in channel or not, if channel name consist its name then it will join the channel otherwise leave the channel.

Answer 2

When someone invite you to join a channel you get call from delegate method

- (void)chatClient:(TwilioChatClient *)client notificationInvitedToChannelWithSid:(NSString *)channelSid { [self displayNotificationForChannelSid:channelSid messagePlaceholder:@"You were invited to channel '%@'."]; }
