这是我自己在github上分享的第一个项目,请大家指点指点
在使用百度地图的时候遇到的一个需求,多点路径规划,按照百度地图官方文档,写的有点麻烦,就自己稍微封装了一下 使用方法
NSArray *keys = @[@"百度大厦",@"天安门",@"长城"];
NSMutableArray *items = [[NSMutableArray alloc]init];
for (int i = 0; i < keys.count; i++) {
YBMKAddressItem *item1 = [[YBMKAddressItem alloc]init];
item1.city = @"北京"; //城市名
item1.key = keys[i]; //关键词
[items addObject:item1];
}
[YBMKMapRoutePlan startBMRoutePlan:items success:^(BMKPolyline *line, NSArray *annotations) {
for (RouteAnnotation* item in annotations) {
[_mapView addAnnotation:item];
}
[_mapView addOverlay:line];
[self mapViewFitPolyLine:line];
}];
新建三个点,按照顺序排列,在block里处理路径规划的结果
1,没有路线的问题是 BMKMapViewDelegate 的两个代理方法没有实现
- (BMKAnnotationView *)mapView:(BMKMapView *)view viewForAnnotation:(id <BMKAnnotation>)annotation
{
if ([annotation isKindOfClass:[RouteAnnotation class]]) {
return [(RouteAnnotation*)annotation getRouteAnnotationView:view];
}
return nil;
}
- (BMKOverlayView*)mapView:(BMKMapView *)map viewForOverlay:(id<BMKOverlay>)overlay
{
if ([overlay isKindOfClass:[BMKPolyline class]]) {
BMKPolylineView* polylineView = [[BMKPolylineView alloc] initWithOverlay:overlay];
polylineView.fillColor = [[UIColor alloc] initWithRed:0 green:1 blue:1 alpha:1];
polylineView.strokeColor = [[UIColor alloc] initWithRed:0 green:0 blue:1 alpha:0.7];
polylineView.lineWidth = 3.0;
return polylineView;
}
return nil;
}
2,图标不对,RouteAnnotation.m 中会制定起点、终点、途径点的图片,按照你自己的需求修改就好
view = [mapview dequeueReusableAnnotationViewWithIdentifier:@"start_node"];
if (view == nil) {
view = [[BMKAnnotationView alloc] initWithAnnotation:self reuseIdentifier:@"start_node"];
view.image = [UIImage imageNamed:@"icon_nav_start.png"];
view.centerOffset = CGPointMake(0, -(view.frame.size.height * 0.5));
}
