Summary

• How to disable user interaction until specific message in GroupChannelViewController

Guide & Code Snippets

Step 1. Create your custom Channel View Controller class that subclasses [SBUGroupChannelViewController]

class CustomGroupChannelViewController: SBUGroupChannelViewController { }

Step 2. Override the view controller methods.

On this page, we have customized an input to be active when two or more messages are received.
The setInputState(:) method can only set the input state on the client.

class CustomGroupChannelViewController: SBUGroupChannelViewController {
    override func baseChannelModule(_ listComponent: SBUBaseChannelModule.List, fullMessagesInTableView tableView: UITableView) -> [BaseMessage] {
        let messageList = super.baseChannelModule(listComponent, fullMessagesInTableView: tableView)
        
        let enabled = messageList.filter({ $0 is UserMessage }).count > 2
        (self.baseInputComponent?.messageInputView as? SBUMessageInputView)?.setInputState(enabled, placeholder: "please select suggested replies.")
        
        return messageList
    }
}

Step 3. Present your view controller.

let vc = CustomChannelViewController(channel: channel) 
let nav = UINavigationController(rootViewController: vc)
yourVc.present(nav, animated: true, completion: nil)    

Result

You can see that the customized screen disables input until the second message is displayed.

You will see that the message field is activated when the conditions are fulfilled.
