Today extension show more and show less option to expand the tableView iOS swift

Problem:

In iOS today extension it will show in notification area with show less and show more option.Based on that i want to display minimum one cell on if it will be in show more condition and display full data if it will be in show less mode.


Solution:

Below function we can change the height based on the user action

    func widgetActiveDisplayModeDidChange(_ activeDisplayMode: NCWidgetDisplayMode, withMaximumSize maxSize: CGSize) {

if (activeDisplayMode == NCWidgetDisplayMode.compact) {
            self.preferredContentSize = maxSize
        }
        else {
            //expanded
            self.preferredContentSize = CGSize(width: maxSize.width, height: CGFloat(CGFloat(list.count*65  // you can replace the 65 with your cell height size
                )))
        }
}
