Can I scroll WKInterfaceGroup programmatically?

Question

I have a label with a long text and a button inside a WKInterfaceGroup. Can I scroll the group to top on the button's touch handler?

Answer 1

You can do this since WatchOS 4. The WKInterfaceController has a function for this.

func scroll(to object: WKInterfaceObject, at scrollPosition: WKInterfaceScrollPosition, animated: Bool)

Simply specify the object (this could for example be a WKInterfaceGroup) you want to scroll to, and specify the scrollPosition on the screen it should scroll to (in your case .top) and you're good. So in your WKInterfaceController class:

scroll(to: objectToShowAtTheTopOfTheScreen, at: .top, animated: true)

Read more on this in the Apple Developer documentation for WKInterfaceController

And the possible values for scrollPosition

Answer 2

No. The only way to programmatically scroll an interface with WatchKit is by scrolling to a specific row in a WKInterfaceTable.
