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

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：

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

@implementation GPSNaviViewController

网友评论

Fintecher:我的 [[AMapNaviDriveManager alloc] init];会crash，楼主遇到过没？
我用的是5.0.1b版本的导航
ea178e3dfb4b:有做添加途径点吗，求指教啊。
FongG:大兄弟，无名道路怎么解决啊啊啊啊啊啊啊！
梁森的简书:代码太多，请原谅我没看完就提问。
实时导航，只需要传递一个起始点和终点的坐标就可以了吗？
LauHao:可以贴一下源码吗
简书不欢迎的程序员:楼主，，这个_currentUL 没有初始化，拿不用户当前位置啊
attackGiant:@看山顶的那只蜗牛这个好像是在上个页面传过来的，你可以自己获取一下
4c8fd9ddcb74:楼主，这个导航车头方向咋一直不变的，能根据用户方向改变而改变吗，不变没办法有直观看到自己所处的方向
梁森的简书:我这个尖头的方向也是没变，有人说是得在屋外，这个我还没试
attackGiant:@4c8fd9ddcb74 导航的时候是实时获取的位置信息，怎么可能方向不变呢。
花开成诗:讲解很详细,还贴心的贴上代码.留下来慢慢学习
LuckiestMan:刚好需要，感谢楼主无私分享！
