iphone - 更改引脚设计

Question

是否可以将 MKAnnotation pin 更改为我自己设计的 png？

Answer 1

覆盖这个并成为 MKMapViewDelegate 的委托(delegate)来实现覆盖方法。

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

创建注释，

MKAnnotationView *annotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];// get a dequeued view for the annotation like a tableview

if (annotationView == nil)
    {
        annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease]; 
    }
    annotationView.annotation = annotation;
    annotationView.canShowCallout = YES; // show the grey popup with location etc
    UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
    ///[rightButton addTarget:self action:@selector(showDetails:) forControlEvents:UIControlEventTouchUpInside];
    annotationView.rightCalloutAccessoryView = rightButton;

    annoationView.image = [UIImage imageNamed:@"random.png"];
