使用PyObjC访问iPhone加速度计

import objc
from PyObjCTools import AppHelper
from Foundation import NSObject
from CoreMotion import CMMotionManager

class AccelerometerDelegate(NSObject):
    def init(self):
        self = super(AccelerometerDelegate, self).init()
        if self is None:
            return None
        self.motionManager = CMMotionManager.alloc().init()
        return self

    def startAccelerometerUpdates(self):
        if self.motionManager.isAccelerometerAvailable():
            self.motionManager.startAccelerometerUpdates()

    def stopAccelerometerUpdates(self):
        if self.motionManager.isAccelerometerActive():
            self.motionManager.stopAccelerometerUpdates()

    def accelerometerData(self):
        if self.motionManager.isAccelerometerActive():
            return self.motionManager.accelerometerData().acceleration()
        return None

delegate = AccelerometerDelegate.alloc().init()
delegate.startAccelerometerUpdates()

# 在这里可以使用delegate.accelerometerData()获取加速度数据
