IntentHandler类：
import Intents
class IntentHandler: INExtension,INStartWorkoutIntentHandling {
public func handle(startWorkout intent: INStartWorkoutIntent,completion: @escaping (INStartWorkoutIntentResponse) -> Void) {
let userActivity = NSUserActivity(activityType: NSStringFromClass(INStartWorkoutIntent.self))
let response = INStartWorkoutIntentResponse(code: .continueInApp,userActivity: userActivity)
completion(response)
}
//MARK: - INStartWorkoutIntentHandling
func confirm(startWorkout intent: INStartWorkoutIntent,completion: @escaping (INStartWorkoutIntentResponse) -> Void) {
completion(INStartWorkoutIntentResponse(code: .continueInApp,userActivity: nil))
}
}
Apple文档说：
Siri打开应用程序,但我需要显示IntentUI的UI.这该怎么做？
换句话说：如何准备显示响应,加载意图UI扩展,准备界面并在代码中显示它？
IntentViewController类：
import IntentsUI
class IntentViewController: UIViewController,INUIHostedViewControlling {
//MARK: - INUIHostedViewControlling
func configure(with interaction: INInteraction!,context: INUIHostedViewContext,completion: ((CGSize) -> Void)!) {
if let completion = completion {
completion(self.desiredSize)
}
}
var desiredSize: CGSize {
return self.extensionContext!.hostedViewMaximumAllowedSize
}
}
基于this教程,它确实可能.
解决方法
虽然Apple说
here：
You can provide an Intents UI extension if you are supporting intents in the following domains:
Messaging
Payments
Ride booking
Workouts
我认为这是不可能的,因为负责开放UI的响应没有为此做好准备：
请查看INSENTMessageIntentResponseCode以了解INSENTMessageIntentHandling：
public enum INSendMessageIntentResponseCode : Int {
case unspecified
case ready
case inProgress
case success
case failure
case failureRequiringAppLaunch
case failureMessageServiceNotAvailable
}
INStartWorkoutIntentHandling的INStartWorkoutIntentResponse和INStartWorkoutIntentResponse：
public enum INStartWorkoutIntentResponseCode : Int {
case unspecified
case ready
case continueInApp
case failure
case failureRequiringAppLaunch
case failureOngoingWorkout
case failureNoMatchingWorkout
}
对于第二个,只有.continueInApp,这正是这里发生的,与存在的第一个相反：.success和.inProgress
