退出信标时获取通知
Posted
技术标签:
【中文标题】退出信标时获取通知【英文标题】：Get notification when exiting from the beacons 【发布时间】：2016-03-03 06:01:44 【问题描述】：我正在与三个 iBeacons 合作，以在 iPhone/iPad 上查找其范围以进行考勤程序。我需要应用程序可以识别三个信标，并且当用户进入任何一个信标的区域时，他们应该收到他们已登录的通知。并且它应该只在用户退出所有三个信标时注销。
同时，如果用户已经登录或进入新的信标，用户不应收到任何通知。（意味着用户将他的位置从一个信标更改为另一个信标的区域）。
在我的代码中，三个信标被识别并获得登录通知。但是退出三个信标时它不会被注销，而在该区域内时它不会被注销并更改为一个信标到另一个信标。
请任何人帮助我解决我的问题。
这是我的代码：

提前致谢！
【问题讨论】：
那是 423 行代码。如果你减少它，你将大大增加获得帮助的机会，更多地关注“最小，完整和可验证的示例”中的“最小”（***.com/help/mcve） 【参考方案1】：您的代码太多，我无法阅读。我并没有真正经历过。
您有 3 个用于 3 个信标（区域）的 UUID。 每次进入/退出，ios 都会有一个回调 didEnterRegion 和 didExitRegion 独立。
您需要做的是使用一个变量来记录 3 个区域的状态，进出。 然后检查每个 didEnterRegion/didExitRegion 回调中的状态，并具有如下规则：
didEnterRegion:
if 0 in 变为 1 in : 用户先进入区域
didExitRegion
如果 x in 变为 0 in (x != 0)：用户首先完全退出该区域
希望对您有所帮助。

对不起，因为我是新手（发布问题），以后会在这里。无论如何感谢您的回答。它对我有用。很抱歉回复晚了。以上是关于退出信标时获取通知的主要内容，如果未能解决你的问题，请参考以下文章
