While using the ViewControllers that is created using ZCUIService, you can use the below method to set the left barbutton item.

func configureLeftBarButtonItem(barbutton: UIBarButtonItem?)

Note:

While using the ZCUIFramework, for slidingPane SectionList to display the notification bell icon, you need to override the computed property `shouldShowNotificationBellIconInSlidingPaneView`

when conforming to `ZCUIServiceDelegate`

var shouldShowNotificationBellIconInSlidingPaneView: Bool {

return true

}

By default it will be false, and it is optional to override this computed property.
