# iOS-HelloCarPlay
工程是基于iOS导航SDK实现的支持CarPlay的导航Demo

## 前述 ##
- [高德官网申请Key](http://lbs.amap.com/dev/#/).
- 阅读[开发指南](http://lbs.amap.com/api/ios-navi-sdk/summary/).
- 通过iOS导航SDK实现了支持CarPlay的导航Demo

## 功能描述 ##
Demo中主要演示了 AMapNaviDriveView 如何适配CarPlay的UI界面，并通过模拟导航展示了整个导航过程，包含了诱导面板、路口放大图的展示、全览、放大缩小拖动地图等操作。

## 核心类/接口 ##
| 类 | 说明 |
| -----|:-----:|
| AMapNaviDriveView	| 驾车导航界面 |
| [AMapNaviDriveManager sharedInstance] | 驾车导航管理类 |
| <CarPlay/CarPlay.h> | CarPlay相关类 |

## 核心难点 ##

`Objective-C`
