iOS仿微信发送实时位置（高德地图

最近项目中要写一个微信那种发送位置的功能。具体功能在于：- 定位到当前位置- 可定位当前位置附近的Poi- 可自行搜索目标位置，并展示附近的poi- 选择当前位置或者选择目标位置进行发送在这里我还是要推荐下我自己建的iOS开发学习群：680565220，群里都是学ios开发的，如果你正在学习ios ，小编欢迎你加入，今天分享的这个案例已经上传到群文件，大家都是软件开发党，不定期分享干货（只有iOS软件开发相关的），包括我自己整理的一份2018最新的iOS进阶资料和高级开发教程


一.准备工作1.首先去高德地图官网下载相关的SDK（如下图）：need-to-insert-img


2.按照高德地图官网的步骤继续添加所需要的依赖库need-to-insert-img


3.根据项目的bundleID前往高德地图API中创建引用并申请相关的key高德地图应用管理后台到这一步前期的准备工作基本差不多了，当然，我这写的不是很具体，详细的引入高德地图SDK还需要耐心按照高德地图官网SDK一步步的去操作二.代码部分1.初始化高德地图SDK在AppleDelegate中引入相关头文件，从高德地图应用管理中找到该应用对用的key值，进行高德地图SDK的初始化操作。直接贴代码部分：#import"AppDelegate.h"#import"ViewController.h"#import <AMapLocationKit/AMapLocationKit.h>#import <AMapFoundationKit/AMapFoundationKit.h>staticNSString*APIKey =@"a1500980e29b7ca7612a46c19e0d2e3a";@interface
