qml插件的SensorGesture不工作

Question

我遵循本教程来检测手机的抖动。这是iOS应用程序开发的一部分。

import QtQuick 2.0
import QtQuick.Layouts 1.1
import QtMultimedia 5.0
import QtGraphicalEffects 1.0
import QtSensors 5.0 as Sensors
SceneBase {
    id: screen
///*** Code of Interest ***///
    Sensors.SensorGesture {
        id: sensorGesture
        enabled: true
        gestures : ["QtSensors.shake"]
        onDetected: {
          console.log("phone shake detected")
        }
    }
/// ************************* ///
    Sensors.Gyroscope {
        id: gyro
        dataRate: 10
        active: true
        onReadingChanged: {
            if (reading.y > 1100){
                console.log("rapid motion detected")
            }
        }
    }
    //... bunch of other code
}

当注释掉与Sensors.SensorGesture有关的代码时，所有其他Sensors都可以正常工作。但是，当代码被取消注释时，它会给出以下错误。

请帮帮我。

自5.13起，iOS 的Qt中不支持传感器手势

请参阅兼容性映射：https://doc.qt.io/qt-5/compatmap.html

我设法用这个扩展来解决这个问题，这个扩展链接到一个.mm文件中的Qt应用程序：

#导入"UIKit/UIKit.h"@实现UIWindow(WoboqWindow(extern void sendShakeDetectedToRootObject((；-(void(motionEnded:(UIEventSubtype(运动withEvent:(UIEvent*(事件{NSLog(@"motionEnded%@"，事件(；if(motion==UIEventSubtypeMotionShake({NSLog(@"摇一摇！"(；sendShakeDetctedToRootObject((；}}-(void(motionBegan:(UIEventSubtype(带有事件的运动：(UIEvent*(事件{NSLog(@"motionBegan%@"，事件(；}@完

有了这个主要的.cpp:

void sendShakeDetectedToRootObject(({QMetaObject:：invokeMethod(rootObject，"shakeDetected"(；}

从QML引擎获得的rootObject。
