我正试图访问苹果手表的陀螺仪。从我读到的内容可以看到它3.不幸的是我无法让它工作。它不断回来“陀螺仪不可用”,所以motionManager.isGyroAvailable总是假的。这是我的代码。任何帮助,将不胜感激。

import WatchKit
import Foundation
import CoreMotion



class InterfaceController: WKInterfaceController {

    let motionManager = CMMotionManager()

    override func awake(withContext context: Any?) {
    super.awake(withContext: context)

    motionManager.gyroUpdateInterval = 0.1

    motionManager.accelerometerUpdateInterval = 0.1
    // Configure interface objects here.
}

override func willActivate() {
    // This method is called when watch view controller is about to be visible to user
    super.willActivate()
    if (motionManager.isGyroAvailable == true) {
        motionManager.startGyroUpdates(to: OperationQueue.current!, withHandler: { (data, error) -> Void in
            guard let data = data else { return }
            let rotationX = data.rotationRate.x
            let rotationY = data.rotationRate.y
            let rotationZ = data.rotationRate.z
            // do you want to want to do with the data
            print(rotationX)
            print(rotationY)
            print(rotationZ)
        })
    } else {
        print("Gyro not available")
    }

根据我的经验(虽然我无法在任何地方找到它),手表上没有原始陀螺仪数据,只有经过处理的数据。您可以使用CMMotionManager方法访问已处理的数据:

startDeviceMotionUpdates(to queue: OperationQueue, withHandler handler: @escaping CMDeviceMotionHandler)

处理程序中的CMDeviceMotion对象具有详细的旋转数据,例如rotation rate,其中的文档表明它是来自陀螺仪的处理数据。还有attitude data
