关于定位打卡

公司需求
给全国67家分公司的员工在APP上做一个打卡签到的功能，之前考虑用苹果原生定位进行实现，发现准确度有问题，后来想了想，决定做成以公司为圆心半径300米范围内可以打卡，结合一些查找的资料，决定使用高德地图进行实现。
效果如图

这是武汉的一个分公司，但是我是在北京的，所以我的位置不在圆圈范围内 界面计较简单，当个人位置在圆圈内时，可以签到，否则不可以。
主要代码如下：
首先项目中需要导入高德的sdk，在高德地图开放平台申请自己APP的key

这样的，安卓和iOS都有 首先pod 高德sdk
pod'AMap3DMap'
pod'AMapSearch'


然后在APPdelegate里面注册一下
[AMapServices sharedServices].apiKey = @"你的应用的key";
然后就是代码环节了：
#define kUIColorFromRGBAlpha(rgbValue) [UIColor \
colorWithRed:((float)((rgbValue &0xFF0000) >>16))/255.0\
green:((float)((rgbValue &0xFF00) >>8))/255.0\
blue:((float)(rgbValue &0xFF))/255.0alpha:0.4]
