如何在iPhone的MKMapView中添加UIImage？

我想在MKMapview中添加UIImage

i、 例如：在一个特定的位置，我想添加一个名为“apple.jpg”的图像

我不知道怎么做

---

因为我已经添加了一个可拖动的pin作为注释。但我不知道是否可以添加多个图像。

有关将图像添加为MKMapView的一部分的信息，请参阅本教程

如果要在MapView上将图像添加为Pin，请使用下面的代码

MKAnnotationView *annotationView = [[[MKAnnotationView alloc] init];

annotationView.image = [UIImage imageNamed:@"apple.png"];
annotationView.annotation = annotation;
annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
annotationView.rightCalloutAccessoryView.tag = 101;

    annotationView.canShowCallout = YES;
 [yourMapView addAnnotation:annotationView];

正如@Kassem Bagher提到的，您需要创建自定义的

MKAnnotationView

，检查任何教程（）

您的图像必须是png格式的，请参见下面的代码

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{

MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"pinView"];
if (!pinView) {
   pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pinView"] autorelease];
   pinView.image = [UIImage imageNamed:@"apple.png"];
   pinView.canShowCallout = YES;
 }
}

-（MKAnnotationView*）地图视图：（MKMapView*）地图视图注释：（id）注释
{
MKPinAnnotationView*pinView=（MKPinAnnotationView*）[mapView出列可重用的AnnotationViewWith Identifier:@“pinView]”；
如果（！pinView）{
pinView=[[MKPinAnnotationView alloc]initWithAnnotation:注释重用标识符：@“pinView”]自动释放]；
pinView.image=[UIImage ImageName:@“apple.png”]；
pinView.canShowCallout=是；
}
}

- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>) annotation
{

MKPinAnnotationView *pinView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"pinView"];
if (!pinView) {
   pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"pinView"] autorelease];
   pinView.image = [UIImage imageNamed:@"apple.png"];
   pinView.canShowCallout = YES;
 }
}

{
MKPinAnnotationView*pinView=（MKPinAnnotationView*）[mapView出列可重用的AnnotationViewWith Identifier:@“pinView]”；
如果（！pinView）{
pinView=[[MKPinAnnotationView alloc]initWithAnnotation:注释重用标识符：@“pinView”]自动释放]；
pinView.image=[UIImage ImageName:@“apple.png”]；
pinView.canShowCallout=是；
}
}

这是工作代码，我已经完成了下面的代码没有必要的图像是.png、.jpg或.gif它的任何格式您都可以使用它

                            if ( pinAnnotation == nil )
                                pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];

           pinAnnotation.image = [UIImage imageNamed:@"marker_postoffice.png"];

       // now you can set diff image by  [annotation title] you  can set diff image with if else condition like below code
