繼 http://www.reibang.com/p/73a6acba45aa 之后的導(dǎo)航功能历葛。
93039.png
線路規(guī)劃主要代碼：
//進(jìn)行路徑規(guī)劃
[self.driveManager calculateDriveRouteWithStartPoints:@[self.startPoint]
endPoints:@[self.endPoint]
wayPoints:nil
drivingStrategy:AMapNaviDrivingStrategySingleDefault];
接下來敘述項目配置：
1价匠、去高德開放平臺下載對應(yīng)的導(dǎo)航AMapNaviKit.framework并解壓
21112.png
2当纱、將AMapNaviKit.framework拖入工程，記得選擇：
121212.png
3踩窖、添加導(dǎo)航需要的資源文件 AMapNavi.bundle坡氯，如圖：
223.png
323.png
4、下面開始代碼部分：（自定義控制器，將下面的代碼復(fù)制進(jìn)控制器即可箫柳，只需要在上個控制器設(shè)置好CLLocationCoordinate2D coor手形、MAUserLocation *currentUL即可進(jìn)行導(dǎo)航功能）
在導(dǎo)航控制器.h文件導(dǎo)入頭文件#import <AMapNaviKit/AMapNaviKit.h>并添加幾個屬性：
@property (nonatomic, strong) AMapNaviDriveManager *driveManager;
@property (nonatomic, strong) AMapNaviDriveView *driveView;
@property (nonatomic, strong) MAUserLocation *currentUL;//導(dǎo)航起始位置，即用戶當(dāng)前的位置
@property (nonatomic, assign) CLLocationCoordinate2D coor;//導(dǎo)航終點位置
導(dǎo)航控制器.m文件：
#import "SpeechSynthesizer.h"
#import "MoreMenuView.h"
@interface GPSNaviViewController ()<AMapNaviDriveManagerDelegate, AMapNaviDriveViewDelegate, MoreMenuViewDelegate>
@property (nonatomic, strong) AMapNaviPoint *startPoint;
