继 http://www.jianshu.com/p/73a6acba45aa 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:nil
drivingStrategy: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
21112.png
2、将AMapNaviKit.framework拖入工程，记得选择：
121212.png
3、添加导航需要的资源文件 AMapNavi.bundle，如图：
223.png

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：
#import "SpeechSynthesizer.h"
#import "MoreMenuView.h"
@interface GPSNaviViewController ()<AMapNaviDriveManagerDelegate, AMapNaviDriveViewDelegate, MoreMenuViewDelegate>
@property (nonatomic, strong) AMapNaviPoint *startPoint;
@property (nonatomic, strong) AMapNaviPoint *endPoint;
@property (nonatomic, strong) MoreMenuView *moreMenu;
@end
