【iOS】高德地图MAMapKit的使用：导航功能。

继上一篇博客之后的导航功能。

线路规划主要代码：

//进行路径规划[self.driveManager calculateDriveRouteWithStartPoints:@[self.startPoint]endPoints:@[self.endPoint]wayPoints:nildrivingStrategy:AMapNaviDrivingStrategySingleDefault];

接下来叙述项目配置：

1、去高德开放平台下载对应的导航AMapNaviKit.framework并解压

2、将AMapNaviKit.framework拖入工程，记得选择：

3、添加导航需要的资源文件 AMapNavi.bundle，如图：

4、下面开始代码部分：（自定义控制器，将下面的代码复制进控制器即可，只需要在上个控制器设置好CLLocationCoordinate2D coor、MAUserLocation *currentUL即可进行导航功能）

在导航控制器.h文件导入头文件#import <AMapNaviKit/AMapNaviKit.h>并添加几个属性：

@property (nonatomic, strong) AMapNaviDriveManager *driveManager;@property (nonatomic, strong) AMapNaviDriveView *driveView;@property (nonatomic, strong) MAUserLocation *currentUL;//导航起始位置，即用户当前的位置@property (nonatomic, assign) CLLocationCoordinate2D coor;//导航终点位置

导航控制器.m文件：

至此，导航功能已经完结。

如有不对的地方请私聊！！！
