前言
最近在開發(fā)一款國外的APP中，需要用到谷歌地圖接剩，記錄下流程切厘。
1.申請谷歌賬號、創(chuàng)建應(yīng)用懊缺、獲取API key
2.項目導(dǎo)入SDK
3.配置plist
4.調(diào)用代理方法實現(xiàn)需求
一疫稿、申請谷歌賬號、創(chuàng)建應(yīng)用、獲取API key
谷歌地圖開放平臺地址:https://cloud.google.com/maps-platform/?hl=zh-CN
如果要查看谷歌地圖的開發(fā)文檔或者APP測試谷歌地圖遗座，都需要翻墻舀凛。
免費的可以使試試 佛跳墻 ，網(wǎng)速也還可以途蒋。
收費的 同學(xué)給推薦了一個socketpro猛遍，買了一個月，19元号坡，網(wǎng)速還可以懊烤。申請賬號流程此處省略。
3.創(chuàng)建項目,創(chuàng)建完項目 切換到該項目下宽堆，創(chuàng)建憑證 獲取apikey, 配置api, 配置的時候 選擇了2個api,Maps SDK for iOS是用來顯示地圖和定位奸晴，Places API 是用來POI檢索用的。
創(chuàng)建項目
創(chuàng)建憑證1
創(chuàng)建憑證2
獲取APIkey
配置API
二日麸、項目導(dǎo)入SDK
用的是cocopod 方式集成的寄啼，手動的 可以去官方文檔查看。
#谷歌地圖
pod'GoogleMaps'
pod'GooglePlaces'
- GoogleMaps：顯示基本的定位功能代箭；
- GooglePlaces：實現(xiàn)搜索功能墩划，官方文檔叫做地點自動完成；
- GooglePlacePicker：是實現(xiàn)獲取某個POI的的詳細信息嗡综，比如名字乙帮、詳細地址、路線等),這個暫時沒用到极景，如果有需要 也導(dǎo)入即可察净。
三、配置plist
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>App需要獲取定位權(quán)限來選擇您的地址</string>
<key>NSLocationWhenInUseUsageDescription</key>
<string>App需要獲取定位權(quán)限來選擇您的地址</string>
四盼樟、調(diào)用代理方法實現(xiàn)需求
1. 導(dǎo)入頭文件
#import <GoogleMaps/GoogleMaps.h>
#import <GooglePlaces/GooglePlaces.h>
#import <CoreLocation/CoreLocation.h>
2. AppDelegate 中的 application:didFinishLaunchingWithOptions 方法下 初始化配置
APIKEY_Google 是 在上面在谷歌后臺獲取的 APIKEY
[GMSServices provideAPIKey:APIKEY_Google];
[GMSPlacesClient provideAPIKey:APIKEY_Google];
3. 地圖顯示頁面代碼如下
JZLocationConverter 主要用來 國內(nèi)坐標(biāo)系的轉(zhuǎn)換
https://github.com/JackZhouCn/JZLocationConverter
APP 如果要測試谷歌地圖 手機必須要翻墻后才行氢卡，下面的代碼隱去了地址的展示，如果有需要自己添加
#import "HGBMapVC1.h"
#import <GoogleMaps/GoogleMaps.h>
#import <GooglePlaces/GooglePlaces.h>
#import <CoreLocation/CoreLocation.h>
