我正在处理前台、后台和杀死（从后台删除）应用程序中的信标检测。我有信标。我kontakt已经实现了位置管理器委托方法，但我无法在前台和后台检测信标，甚至没有调用方法didEnterRegion和 didExitRegion。对于解决方案我将位置管理器委托与 KTKDevicesManagerDelegate 合并。我无法在位置管理器中检测到信标，所以我尝试在我开始的位置管理器方法的 didRangeBeacons 中实现devicesManager.startDevicesDiscovery()KTKDeviceManagerDelegate 的那个时间在前台和后台检测信标，但是当我们杀死应用程序时我无法检测到信标。我已经在 Info.plist 中添加了 NSBluetoothPeripheralUsageDescription 、 NSLocationAlwaysUsageDescription 、 NSLocationWhenInUseUsageDescription 、 bluetooth-central 、 fetch 、 location 。我在 didFinishLaunchingWithOptions 上添加了以下内容requestAlwaysAuthorization(),requestWhenInUseAuthorization()。
