接口没有定义视图控制器 class

Question

我正在尝试根据此 WWDC video from apple 制作一个锻炼应用程序，不幸的是，有些方法在 WatchOS 4 中已被弃用，我无法使代码正常工作。每次单击其中一个按钮开始锻炼时，屏幕都会变黑，并且出现错误 Extension[11692:537762] [default] -[SPApplicationDelegate companionConnection:reloadRootInterfaceViewControllersWithNames:initializationContextIDs:pageIndex:verticalPaging:]:1432: Error - interface does not define view controller class 'WorkoutInterfaceController'

第二个视图控制器 "WorkoutInterfaceController" 在故事板中并链接到它的 class。

我的 WKInterfaceController class:

class InterfaceController: WKInterfaceController {

@IBOutlet var outdoorBtn: WKInterfaceButton!
@IBOutlet var indoorBtn: WKInterfaceButton!

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()
}

override func didDeactivate() {
    // This method is called when watch view controller is no longer visible
    super.didDeactivate()
}

@IBAction func didTapOutdoorButton() {
    let workoutConfiguration = HKWorkoutConfiguration()
    workoutConfiguration.activityType = .walking
    workoutConfiguration.locationType = .outdoor


    // Pass configuration to next interface controller
    WKInterfaceController.reloadRootPageControllers(withNames: ["WorkoutInterfaceController"], contexts: [workoutConfiguration], orientation: .horizontal, pageIndex: 0)
}

@IBAction func didTapIndoorSaButton() {
    let workoutConfiguration = HKWorkoutConfiguration()
    workoutConfiguration.activityType = .walking
    workoutConfiguration.locationType = .indoor

    // Pass configuration to next interface controller
    WKInterfaceController.reloadRootPageControllers(withNames: ["WorkoutInterfaceController"], contexts: [workoutConfiguration], orientation: .horizontal, pageIndex: 0)
}
}

非常感谢您的帮助！

Answer 1

视图控制器缺少情节提要中的标识符

Answer 2

此外，withNames 列表表示接口控制器的标识符列表，而不是接口控制器 class 名称。请看图片：

WKInterfaceController.reloadRootPageControllers(withNames: ["WizardPage2"], contexts: nil, orientation: .horizontal, pageIndex: 0)

接口没有定义视图控制器 class

interface does not define view controller class
