使用地图，使用最多的也是百度地图API，以前使用百度地图只是表面地引用一下方法，很少点进方法或者对应属性的文件中，去查看其对应的说明与含义。
1.百度地图两点之间的距离
1 /** 2 3 *计算指定两点之间的距离 4 5 *@param a 第一个坐标点 6 7 *@param b 第二个坐标点 8 9 *@return 两点之间的距离，单位：米 10 11 */ 12 13 UIKIT_EXTERN CLLocationDistance BMKMetersBetweenMapPoints(BMKMapPoint a, BMKMapPoint b);
BMKMetersBetweenMapPoints方法只是两个经纬度之间的直线距离
2.路线实际距离
1 ///此类表示一条驾车路线
2 @interface BMKDrivingRouteLine : BMKRouteLine{
3 bool _isSupportTraffic;//从2.7.0开始，废弃
4 NSArray* _wayPoints;
5 }
6 ///该路线所在区域是否含有交通流量信息，从2.7.0开始，废弃
7 @property (nonatomic) bool isSupportTraffic;
8 ///路线途经点列表，成员类型为BMKPlanNode
9 @property (nonatomic, strong) NSArray* wayPoints;
10 @end
1 ///此类表示路线数据结构的基类,表示一条路线，路线可能包括：路线规划中的换乘/驾车/步行路线
2 ///此类为路线数据结构的基类，一般关注其子类对象即可，无需直接生成该类对象
3 @interface BMKRouteLine : NSObject{
4 int _distance;
5 BMKTime* _duration;
6 BMKRouteNode* _starting;
7 BMKRouteNode* _terminal;
8 NSString* _title;
9 NSArray* _steps;
10 }
11 ///路线长度 单位： 米
12 @property (nonatomic) int distance;
13 ///路线耗时 单位： 秒
14 @property (nonatomic, strong) BMKTime* duration;
15 ///路线起点信息
16 @property (nonatomic, strong) BMKRouteNode* starting;
17 ///路线终点信息
18 @property (nonatomic, strong) BMKRouteNode* terminal;
19 ///路线名称(预留字段，现为空)
20 @property (nonatomic, strong) NSString* title;
21 ///路线中的所有路段，成员类型为BMKWalkingStep，BMKDrivingStep，BMKTransitStep
22 @property (nonatomic, strong) NSArray* steps;
23 @end
将MBKDrivingRouteLine实例化，通过distance属性获取实际驾车路线距离
