如何通过kivy访问iPhone的位置？

from kivy.app import App
from pyobjus import autoclass

CLLocationManager = autoclass('CLLocationManager')
CLLocation = autoclass('CLLocation')

class MyApp(App):
    def build(self):
        self.location_manager = CLLocationManager.alloc().init()
        self.location_manager.setDelegate_(self)
        return YourRootWidget()

class MyApp(App):
    # ...

    def locationManager_didUpdateLocations_(self, manager, locations):
        location = locations.lastObject()
        latitude = location.coordinate().latitude
        longitude = location.coordinate().longitude
        # 处理获取到的位置信息

class MyApp(App):
    # ...

    def on_start(self):
        self.location_manager.requestWhenInUseAuthorization()
        self.location_manager.startUpdatingLocation()
