ios - Swift 区域监控本地通知触发器

Question

我正在开发一个应用程序来在进入某个区域时触发本地通知。但是，有时当手机被锁定时，即使我已经在该地区待了一段时间，通知也没有弹出。只有按下电源/主页按钮时才会显示通知弹出窗口(手机仍处于锁定模式)。

一般来说，一切似乎都正常，除了有时只有在按下电源/主页按钮唤醒手机时才会显示通知，尽管它仍然处于锁定状态。

希望有人能赐教! =)

Answer 1

根据开发商documentation .在核心位置框架中，有两个服务可以为您提供当前位置信息。

1. The standard location service is a configurable, general-purpose solution for getting location data and tracking location changes for the specified level of accuracy.

2. The significant-change location service delivers updates only when there has been a significant change in the device’s location, such as 500 meters or more.

您需要使用标准定位服务来在后台监控位置

If your iOS app must keep monitoring location even while it’s in the background, use the standard location service and specify the location value of the UIBackgroundModes key to continue running in the background and receiving location updates. (In this situation, you should also make sure the location manager’s pausesLocationUpdatesAutomatically property is set to YES to help conserve power.)
