Google Maps SDK for iOS 谷歌地图使用总结
Maps SDK for Android Overview

前段时间因为公司需要给维修人员更方便的前往店主的店面，所以增加了谷歌GPS定位获取,所以就专门去看了一下谷歌地图，花了点时间熟悉了一下，接入谷歌地图,最简单的方法就是通过CocoaPods接入，
导入"pod'GoogleMaps' 和pod'GooglePlaces'"两个SDK，然后在AppDelegate页面.m文件导入头文件(或宏文件)
//谷歌地图

import <GoogleMaps/GoogleMaps.h>

import <GooglePlaces/GooglePlaces.h>

import <CoreLocation/CoreLocation.h>

然后在didFinishLaunchingWithOptions 方法中加入
[GMSServices provideAPIKey:@"贵公司在谷歌地图申请的apikey"];
[GMSPlacesClient provideAPIKey:@"贵公司在谷歌地图申请的apikey"];
一定一定要在谷歌地图启用”Maps SDK for iOS“和“Places API”,特别是Places API，如果不启用,地图就很可能不显示内容，

接着就创建一个控制器,名字看自己
直接贴代码

需要注意的是，代码里有一部分例如跳转按钮和换定位按钮是我自己用的需求，不是地图必须要的，到时候你们直接把代码复制进去然后把需要的留下不需要的删了。

里面最关键的就是实现了长按手势标记位置更新位置信息，这个我找了很久，很多文章才找到这个监听方法，谷歌地图文档很多都写着几句话我就懒得看，我都是搜索引擎找答案
