I have a WKCrownSequencer that triggers an action in my pushed interface controller and the first time through everything works fine. When I go back to root interface controller regardless of the method (pop or reloadRootcontrollers) the digital crown no longer works in first interface controller nor the second one. The StartInterfaceController is the rootInterfaceController and the MidWorkoutInterfaceController is the pushed one.
import WatchKit
import Foundation
class StartInterfaceController:
WKInterfaceController,CLLocationManagerDelegate {
override func awake(withContext context: Any?) {
super.awake(withContext: context)
// Configure interface objects here.
}
override func willActivate() {
// This method is called when watch view controller is about to be visible to user
super.willActivate()
}
@IBAction func start() {
WKInterfaceController.reloadRootControllers(
withNames: ["midWorkout"], contexts: []
)
}
The second interface controller is below.
import WatchKit
import Foundation
class MidWorkoutInterfaceController: WKInterfaceController, WKCrownDelegate {
override func awake(withContext context: Any?) {
super.awake(withContext: context)
print("viewdidAwake")
