uber_不使用应用程序时如何阻止Uber跟踪iPhone的位置
uber
Most iOS apps that require your location give you a choice: you can “Always” grant it access, or only grant it access “While Using the App”. Uber, however, only gave you an “Always” or “Never” choice, which means it could track you after your ride ends and you stop using the app. And they did just that.
大多数需要您所在位置的iOS应用程序都为您提供了一个选择：您可以“始终”授予其访问权限，或仅“在使用应用程序时”授予其访问权限。 但是，Uber只为您提供了“始终”或“从不”的选择，这意味着它可以在您的旅程结束并且停止使用该应用程序后跟踪您。 他们就是这样做的。
With iOS 11, that finally changed—Apple forced apps to offer the “While Using” option for location permissions. Uber claims they’ve stopped this practice, but the iPhone app still “Always” has access to your location unless you revoke that previously-granted access. And as long as it has that permission, Uber could start tracking you outside of the app whenever it wants to.
最终，随着iOS 11的改变，Apple迫使应用程序提供“使用时”选项以获取位置权限。 Uber声称他们已经停止了这种做法 ，但是iPhone应用程序仍然“始终”有权访问您的位置，除非您撤消了之前授予的访问权限。 而且，只要拥有该许可，Uber就可以在需要时随时在应用程序外部跟踪您。
To revoke Uber’s ability to always track your location, head to Settings > Privacy > Location Services on your iPhone.
要取消Uber始终跟踪您的位置的功能，请转到iPhone上的“设置”>“隐私”>“位置服务”。
Scroll down and tap the “Uber” app in the list. Tap “While Using” and Uber will only have access to your location while you’re actually using the app.
向下滚动并在列表中点击“ Uber”应用。 点按“使用时”，Uber将仅在您实际使用该应用程序时访问您的位置。
(If you also have Lyft installed, you don’t need to worry about this. Lyft only allows you to choose between “Never” and “While Using”, so you can’t even provide “Always” access to the Lyft app. Good on you, Lyft.)
(如果您还安装了Lyft，则无需担心。Lyft仅允许您在“从不”和“使用时”之间进行选择，因此，您甚至无法“始终”访问Lyft应用程序。很好，Lyft。)
While you’re here, you should probably scroll through the list and see which other apps “Always” have access to your location. If you don’t trust an app with access to your location, you can tap it and select “While Using” instead.
在这里时，您可能应该滚动浏览列表，查看“始终”有哪些其他应用有权访问您的位置。 如果您不信任可以访问您的位置的应用，则可以点击它，然后选择“使用时”。
Note that certain features may not work if you disable this for some apps. For example, a weather app that runs in the background and sends you notifications about the weather won’t be able to update your location in the background unless you give it this location access.
请注意，如果您对某些应用禁用此功能，则某些功能可能无法使用。 例如，在后台运行并向您发送有关天气的通知的天气应用程序将无法在后台更新您的位置，除非您授予其此位置访问权限。
