iOSLibHTMLViewer - UBogun/Xojo-iosLib GitHub Wiki
Native class: AppleWebView
Inherits from: iOSLibCanvas
iOSLibHTMLViewer is the custom control of iOSLib containing an AppleWebView as object, which means it is a replacement for Xojo’s iOSHTMLViewer. You will only need to use this custom control if you want to handle the events returned by this class; every other feature is available for Xojo iOSHTMLViewer transparently via the iOSLibHTMLViewerExtension.
Like all iOSLib custom controls, the control is a wrapper that contains the view and performs translations between Xojo and iOS classes / data types transparently whereever possible.
Like all iOSLib custom controls, if you want to attain maximum performance, you can always address the iOSClass itself via the Controls ID object. The ID object is always the View subclass itself, in this case AppleWebView. The iOS class expects Apple native objects and data types of course. You can always use the included translation methods to bridge from Xojo types and classes to iOS.
