你好，请问下如果我第一次打开app，然后注册了需要监测的UUID，然后过段时间我把app退出了，那app还会监测Beacon的进入或退出么？还会接收到通知么？

用 [startMonitoringForRegion:](https://aprilbrother.github.io/aprilbeacon-ios-sdk/Documents/Classes/ABBeaconManager.html#//api/name/startMonitoringForRegion:) 这个方法，在退出app甚至杀死app的情况下，仍然可以监测beacon

也就是只要我第一次打开了app，把需要监测的UUID都注册了，开启了StartMonior，只要我不stop它，无论后台还是杀死app，都会一直会监测beacon区域，是这样么？

是的，这个特性是从iOS 7.1.2之后开始支持的
