Channel Membership

You can observe the live channel to determine changes in the membership status. If user is banned from the channel, you would want to show appropriate UI and move from the chat screen.

Channel Members

When a user joins a channel, they are able to observe and chat with other users in that channel. They are also automatically considered a member of that channel. The Chat SDK provides the ability to view which users are currently in the channel as well as invite other users to join the channel.

Each channel is identified by a unique channelId, which is any string that uniquely identifies the channel and is immutable through its lifetime. When creating channels, you can specify your own channelId, or leave it to Amity's Chat SDK to automatically generate one for you.

It's important to note that, createChannel: guarantees that the requested channel is a new channel, whereas joinChannel: will attempt to join an existing channel. If there is a requirement to create a new channel, then use of createChannel: then call joinChannel:. Lastly calling getChannel: only gives you back the channel LiveObject, but it won't make the current user join said channel.
