CLLocationManager不会停止 [英] CLLocationManager don't stop

问题描述

亲爱的开发人员，

我正在努力寻找解决CLLocationManager问题的解决方案。

I am trying hard to find a solution for my problem regarfing CLLocationManager.

我在我的应用程序中使用CLLocationManager实例。如果用户选择设备上的主页按钮或终止应用程序，我希望位置服务停止。

I use a CLLocationManager instance in my Application. If the user selects the Home button on the device or terminates the application I want the location services to stop.

因此我调用 [self.locationManager stopUpdatingLocation]; - 但这在某种程度上不起作用。应用程序进入后台，状态栏右上角的小位置箭头不会消失。即使我添加 [self.locationManager release] 或 self.locationManager.delegate = nil; - 位置跟踪停止： - /

Therefor I call [self.locationManager stopUpdatingLocation]; - But this somehow doesn't work. The application enters the background and the small location arrow in the upper right corner of the status bar don't disappear. Even if I add [self.locationManager release] or self.locationManager.delegate = nil; - the location tracking don't stop :-/

如果我转到我的设备设置并关闭应用程序的位置服务，它就会消失。每当我切换回位置服务时，我立即在开关切换旁边看到一个紫色的箭头，图标会重新出现在状态栏中。

It only disappears if I go to my device settings and switch off location services for the app. Whenever I switch back to location service enabled I immediately get a purple colored arrow next to the switch toggle and the icon reappears in the status bar.

我的问题是我怎么能当应用程序进入后台或被终止时关闭位置服务？

My question is how can I turn off location services when the app enters the background or is terminated?

提前多多感谢并祝你有个愉快的一天： - ）

Thanks a lot in advance and have a nice day :-)

推荐答案

你这样做是正确的。输入背景时，如果调用某些委托方法几秒钟就可以了。那应该停止。

You do it the right way. When entering background, it's ok if some delegate methods are called for some seconds. That should stop.

你在哪里停止位置更新？你确定它被触发了吗？如果是，即使可视指示器告诉别的东西，你的委托方法是否被调用？

Where do you stop the location updates ? Are you sure it is triggered ? If yes, are your delegate method called even if the visual indicators tell something else ?

你确定你没有触发一个重新激活位置更新的方法吗？停止它（因为例如，即使停止后你也可以收到一些更新）。

Are you sure you don't trigger a method that reactivate the location update after you have stopped it (because for example you can receive some updates even after stopped).
