Guide & Snippet

    override func createViewModel(channelListQuery: GroupChannelListQuery?) {
        self.showLoading(true)
        super.createViewModel(channelListQuery: channelListQuery)
    }
    
    override func shouldUpdateLoadingState(_ isLoading: Bool) {
        if self.viewModel != nil {
            self.showLoading(isLoading)
        }
    }
    
    override func groupChannelListViewModel(
        _ viewModel: SBUGroupChannelListViewModel,
        didChangeChannelList channels: [GroupChannel]?,
        needsToReload: Bool
    ) {
        super.groupChannelListViewModel(
            viewModel,
            didChangeChannelList: channels,
            needsToReload: needsToReload
        )
        self.showLoading(false)
    }
}

• Before using a customized viewController class, please set it in the SBUViewControllerSet.

SBUViewControllerSet.GroupChannelListViewController = CustomGroupChannelListViewController.self
