我在我的项目中使用OCMapView。OCMapView 是Map Kit 集群定位点。
我想在 mapkit 上添加行。像这样
但是我的代码这样做:添加到地图上的覆盖线是不合逻辑的。
我处理这段代码。
CLLocationCoordinate2D *coordinates
= malloc(sizeof(CLLocationCoordinate2D) * [self.mapView.annotations count]);
for (int i=0; i<[self.mapView.annotations count]; i++) {
OCMapViewSampleHelpAnnotation * ann=[annodationArray objectAtIndex:i];
coordinates[i]=ann.coordinate;
}
self.routeLineView=nil;
self.routeLine = [MKPolyline polylineWithCoordinates:coordinates count:self.mapView.annotations.count]; //
free(coordinates);
[self.mapView setVisibleMapRect:[self.routeLine boundingMapRect]]; //If you want the route to be visible
dispatch_async(dispatch_get_main_queue(), ^{
[self.mapView addOverlay:self.routeLine];
});
你可以看到我的叠加层法
- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay{
//normally here is circle.
if(overlay == self.routeLine)
{
if(nil == self.routeLineView)
{
self.routeLineView = [[MKPolylineView alloc] initWithPolyline:self.routeLine];
self.routeLineView.fillColor = [UIColor redColor];
self.routeLineView.strokeColor = [UIColor redColor];
self.routeLineView.lineWidth = 3;
}
return self.routeLineView;
}
return nil;
}
我也在分享我的项目代码。我怎么解决这个问题 ?
