自定义室内地图以及路径规划
最近做到一个项目，设计到室内地图路径规划，其实一般的项目也很少设计到室内路径规划，室内也就那么点大。
但是上面怎么说我们就怎么做吧，或者是人性化，或者是多此一举的项目，既然写了就分享出来吧。
先说下大致思想流程吧，语言表达不是很好，有不懂的可以加我的qq24272779询问！
上图例子：
基本思路把上图建筑区域全部用坐标扣选出来，也就是不能走到的地方，蓝色区域和灰色区域。
坐标点以像素为单位。
扣选出来以后把整个图片地图分成由好多小方格组成的！
选择两个点，用A＊算法求出需要经过非蓝色和灰色区域的最短路径。
（A＊算法不懂的可以百度）。
代码：
／／添加地图图片
SKIndoorMapView *indoorMap = [[SKIndoorMapView alloc]initWithIndoorMapImageName:@"WHTerminalBD.png" Frame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];
[self.view addSubview:indoorMap];／／长安选择起点和终点
#pragma mark - Zoom methods
-(void)longRequired:(UIGestureRecognizer*)gesture
{
if (gesture.state == UIGestureRecognizerStateBegan)
{
if (Points.count == 0 || Points.count >= 2)
{
[Points removeAllObjects];
for (UIView *view in [self.mapView subviews])
{
[view removeFromSuperview];
}
//坐标
CGPoint touchPoint = [gesture locationInView:self.mapView];
UIImage *Img = [UIImage imageNamed:@"startPoint"];
UIImageView *imgView = [[UIImageView alloc]initWithImage:Img];
[imgView setFrame:CGRectMake(touchPoint.x - (Img.size.width / (self.zoomScale*2)), touchPoint.y - (Img.size.width / (self.zoomScale)), Img.size.width / self.zoomScale, Img.size.height / self.zoomScale)];
[self.mapView addSubview:imgView];
[Points addObject:NSStringFromCGPoint(touchPoint)];
}
else if (Points.count == 1)
{
//坐标
CGPoint touchPoint = [gesture locationInView:self.mapView];
UIImage *Img = [UIImage imageNamed:@"endPoint"];
UIImageView *imgView = [[UIImageView alloc]initWithImage:Img];
[imgView setFrame:CGRectMake(touchPoint.x - (Img.size.width / (self.zoomScale*2)), touchPoint.y - (Img.size.width / (self.zoomScale)), Img.size.width / self.zoomScale, Img.size.height / self.zoomScale)];
[self.mapView addSubview:imgView];
[Points addObject:NSStringFromCGPoint(touchPoint)];
[self RoadRecevied:Points];
}
}
}
#pragma 路径
-(void)RoadRecevied:(NSMutableArray *)Arr
{
/* 路径规划 */
AStar *astar = [[AStar alloc]init];
data = [astar findPath:CGPointFromString(Arr[0]).x curY:CGPointFromString(Arr[0]).y aimX:CGPointFromString(Arr[1]).x aimY:CGPointFromString(Arr[1]).y];
/*

opaque—透明开关，如果图形完全不用透明，设置为YES以优化位图的存储。

*/
UIGraphicsBeginImageContextWithOptions(CGSizeMake(320, 480), NO, [UIScreen mainScreen].scale);
UIBezierPath *path = [UIBezierPath bezierPath];
[[UIColor redColor] setStroke];
[path setLineWidth:0.5];
[path setLineJoinStyle:kCGLineJoinRound];
[path setLineCapStyle:kCGLineCapRound];
BOOL isfirst = YES;
if (data && [data count] > 0)
{
for (id obj in data)
{
if (isfirst)
{
isfirst = NO;
[path moveToPoint:CGPointMake([obj id_col], [obj id_row])];//设置起始路径的点
}
[path addLineToPoint:CGPointMake([obj id_col], [obj id_row])];
}
}
[path stroke];
UIImage *img =UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageView *imgV = [[UIImageView alloc]initWithImage:img];
[_mapView addSubview:imgV];
[self setNeedsDisplay];
}
