Offline Banner Message View¶
FUIOfflineBannerMessageView
¶
public class FUIOfflineBannerMessageView: FUIBannerMessageView
FUIOfflineBannerMessageView
shows an overlay message centered in the screen underneath a navigation bar. FUIOfflineBannerMessageView
must be attached to a FUINavigationBar
to make it work properly.
FUIOfflineBannerMessageView
is a subclass of FUIBannerMessageView
and FUINavigationBar
can contain only one FUIBannerMessageView
.
Call show()
on a FUIOfflineBannerMessageView
instance to show the message. By default, the message is shown centered on screen for four seconds.
Usage¶
Usually, the creation of FUIOfflineBannerMessageView
and attachment to FUINavigationBar
is
in the viewDidAppear
function of a UIViewController
. As the code indicates below:
override public func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
guard let navBar = self.navigationController?.navigationBar as? FUINavigationBar else {
return
}
let offlineBannerView = FUIOfflineBannerMessageView()
navBar.bannerView = offlineBannerView
offlineBannerView.show(message: "200k pending to upload example with text showing wrapping to two lines")
self.offlineBanner = offlineBannerView
}
