iOS MapKit自定义引脚

如何在地图中显示图像而不是图钉。 到目前为止，我只能添加引脚。 .m的示例代码将非常有帮助，因为我还是iOS编程的新手。

Answer 1

#pragma mark - #pragma mark MKMapView delegate - (MKAnnotationView *)mapView:(MKMapView *)mapview viewForAnnotation:(id <MKAnnotation>)annotation { if ([annotation isKindOfClass:[MKUserLocation class]]) return nil; static NSString* AnnotationIdentifier = @"AnnotationIdentifier"; MKAnnotationView *annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationIdentifier]; if(annotationView) return annotationView; else { MKAnnotationView *annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationIdentifier] autorelease]; annotationView.canShowCallout = YES; annotationView.image = [UIImage imageNamed:@"someImage.png"]; UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; [rightButton addTarget:self action:@selector(writeSomething:) forControlEvents:UIControlEventTouchUpInside]; [rightButton setTitle:annotation.title forState:UIControlStateNormal]; annotationView.rightCalloutAccessoryView = rightButton; annotationView.canShowCallout = YES; annotationView.draggable = YES; return annotationView; } return nil; } 

编辑：

我可以向你解释有关MKAnnotationView所有信息，但是我认为你会发现苹果公司提供的文档比任何其他来源都要好得多。 检查链接中的概述部分。

去Xcode的组织者，然后去文档和searchweatherMap它显示包含图像注记的地图的例子。
