在WWDC 2024的“What's new in location authorization”会议中，苹果介绍了定位权限的不同选项，包括“使用App期间”和“始终”两种授权方式。

  • “使用App期间”（When in Use）：这种授权方式允许应用在用户正在使用应用时访问位置信息。当应用进入后台或用户不再使用应用时，应用将无法继续访问位置信息。这种方式适用于用户只希望在特定情况下（如导航或查找附近的服务）共享位置信息的场景。

  • “始终”（Always）：这种授权方式允许应用在后台持续访问位置信息，即使用户没有主动使用应用。这对于需要持续跟踪用户位置的应用（如健身追踪应用）非常有用。然而，苹果强调，从今年开始，“始终”授权只有在应用处于前台时才能生效，并且需要显式地创建CL服务会话。
