WhirlyGlobe初识（一）

直线

//核心方法
- (nonnull instancetype)initWithLineString:(MaplyCoordinate *__nonnull)coords numCoords:(int)numCoords attributes:(NSDictionary *__nullable)attr;

NSMutableArray *lineArr = [NSMutableArray array];
int count = 2;//点的数量
MaplyCoordinate coords[count];//每个点对象放入coords里面
for (int i = 0; i<locationPointArr.count; i++) {
      EELocation *tmpLoc = locationPointArr[i];
       coords[i] = MaplyCoordinateMakeWithDegrees(tmpLoc.longitude,tmpLoc.latitude]);
  }
MaplyVectorObject *vec = [[MaplyVectorObject alloc] initWithLineString:coords numCoords:count attributes:nil];
                [lineArr addObject:vec];

MaplyComponentObject *lineObj = [baseView addWideVectors:lineArr desc:nil];//MaplyBaseViewController *baseView

虚线

思路：用一张2种不同的颜色相间图片，绘制而成的
kMaplyWideVecTexRepeatLen: @(113),//开始重复的长度* 这个属性很重要
