更改引脚颜色MKMapView [英] Changing pin color MKMapView

问题描述

我以这种方式向地图添加注释：

I add annotations to my map in this way:

MyAnnotation *annotationPoint2 = [[MyAnnotation alloc] init];
annotationPoint2.coordinate = anyLocation;
annotationPoint2.title = [NSString stringWithFormat:@"%@", obj];
annotationPoint2.subtitle = @"";  //or set to nil
annotationPoint2.keyValue = [NSString stringWithFormat:@"%@", key];
[mapPins addAnnotation:annotationPoint2];

针脚都是红色的，我希望它们都是绿色的。我怎样才能改变颜色？我尝试了以下内容，但仍然给出了红色标记：

The pins are all red, and I would like them all green. How can I change the color? I have tried the following, but it still gives a red mark:

annotationPoint2.pinColor = MKPinAnnotationColorGreen;

推荐答案

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation 
  {
    MKPinAnnotationView *annView=[[MKPinAnnotationView alloc]initWithAnnotation:annotation reuseIdentifier:@"pin"];
    annView.pinColor = MKPinAnnotationColorGreen;
    return annView;
  }
