为什么当我想要生成触觉反馈时出现错误

Question

我正在 SwiftUI 中编写一个计时器。 当我的计时器完成后，我想要进行触觉返回，我想要像手机上的闹钟一样相当重的振动。

问题是，当触觉返回发生时，没有任何反应，并且我在终端上收到错误消息。

错误如下：

CAReportingClient.mm:532 Attempted to remove a reporter not created by this client { careporter_id=16 578 573 762 561 }

这是我的代码：

import Foundation
import SwiftUI
import CoreHaptics

struct Exercice_TimerButton: View {
    @State var totalSeconds: Int
    @State public var remainingSeconds: Int
    @State private var timer: Timer?

    var body: some View {
        ZStack(alignment:.leading) {
                Rectangle()
                .foregroundColor(Constants.color_background2)
                    .frame(width: width, height: height)
                    .cornerRadius(20)
                
                Rectangle()
                .foregroundColor(Constants.color_primaire2)
                    .frame(width: calculateProgressBarWidth(), height: height)
                    .cornerRadius(20)
            
            Text("\(remainingSeconds) secondes")
                .font(.system(size: 15, weight: .regular, width: .expanded))
                .foregroundColor(Constants.color_text2)
                .frame(width: UIScreen.main.bounds.width - 60, height:height)
               
        }
        .frame(width:CGFloat(UIScreen.screenWidth - 60),height:40)
        .onAppear {
            startTimer()
        }
        .padding(.all,35)
    }
    
    private func startTimer() {
        timer = Timer.scheduledTimer(withTimeInterval: 1.0, repeats: true) { timer in
                withAnimation(.linear(duration: 1.0)) {
                    updateTimer()
                }
            }
        }
    
    private func updateTimer() {
          guard remainingSeconds > 0 else {
              // Timer completed, stop the timer
              timer?.invalidate()
              generateAlarmVibration() //HERE I WANT TO EXECUTE THE VIBRATIONS
              return
          }
          
          remainingSeconds -= 1
          
        
      }
      
    
    private func calculateProgressBarWidth() -> CGFloat {
        let progressPercentage = CGFloat(remainingSeconds) / CGFloat(totalSeconds)
        return width * (1.0 - progressPercentage)
    }

//FROM HERE ON, THE PART FOR HAPTIC FEEDBACK


    private func generateAlarmVibration() {
           // Create haptic events
           let hapticEvents = createHapticEvents()

            var events: [CHHapticEvent] = []
            
            // First loop
            for i in stride(from: 0, to: 1, by: 0.1) {
                let intensity = CHHapticEventParameter(parameterID: .hapticIntensity, value: Float(i))
                let sharpness = CHHapticEventParameter(parameterID: .hapticSharpness, value: Float(i))
                let event = CHHapticEvent(eventType: .hapticTransient, parameters: [intensity, sharpness], relativeTime: i)
                events.append(event)
            }
            
            // Second loop
            for i in stride(from: 0, to: 1, by: 0.1) {

        }
    private func playHapticEvents(events: [CHHapticEvent]) {
            // Check if the device supports haptic feedback
            guard CHHapticEngine.capabilitiesForHardware().supportsHaptics else {
                print("Device does not support haptic feedback.")
                return
            }

            do {
                // Create the haptic engine
                let engine = try CHHapticEngine()
                try engine.start()

                // Create a haptic pattern
                let pattern = try CHHapticPattern(events: events, parameters: [])

                // Create a haptic player and play the pattern
                let player = try engine.makePlayer(with: pattern)
                try player.start(atTime: 0)

如果您有任何想法，我很乐意听取您的意见， 预先感谢。

我已经尝试了几种振动方法，经典的振动（成功、错误......）效果很好，但我想要更高级的东西。每次铃声响起，我都会收到相同的错误消息。

Answer 1

嘿，我确实有完全相同的代码和相同的问题，我喜欢你实现更高级触觉的方式，并且除了成功完全错误之外我有相同的想法......并且想要更多的控制。我初始化了核心触觉框架的 CHEngine 类似的东西并经常使用它，但随后我得到的 CAREportingClient.mm:532 与你每次使用不同的carereporter ID号完全相同

如果您找到修复程序，请告诉我（+如果我成功，我会通知您）这是新的，从 iOS 17 才开始，对吗？以前从未见过它，现在它堵塞了 XCode 日志并控制台每次与触觉的交互。
