Using watch crown to control a WKInterfaceSlider

I would like to use the apple watch crown to control a slider. Is this possible?

If so, how?

Apple uses it to change the colours on the UI of the watch.

EDIT: so it seems not possible at the moment (see answers below). Is important to notice that in two weeks time (Apple WWDC 2015) this could change (maybe a Watch OS for independent apps?)

Solution

  • Not possible. You don't have the crown in control – it's used only automatically for scrolling etc..

    Apple guidelines:

    "Scrolling is the only supported Digital Crown interaction for apps, and the system automatically manages those interactions for you. Apps do not have direct access to the Digital Crown."

    Apple might enable digital crown when the Apple Watch native apps are out (we will see in 2 weeks at WWDC).
