Question

我一直在做一个应用来检测信标。当应用程序处于前台或屏幕打开时，该应用程序运行良好。但是当屏幕关闭时，没有调用locationManager：didEnterRegion方法。据我所知，应该以任一方式调用locationManager：didEnterRegion。

我尝试了许多场景，例如在输入区域后等待15分钟以上，不同的配置（notifyEntryStateOnDisplay = true或false）......但结果是相同的。 locationManager：在解锁手机之前，不会调用didEnterRegion方法。

PS：当屏幕关闭时，locationManager：didExitRegion被正确调用。

我使用iPhone 5,5S和6 plus来测试IOS 8.1上的应用程序

编辑：＆＃34;位置更新＆＃34;和＆＃34;使用蓝牙LE配件＆＃34;已启用

感谢您的回答。
