MKMapView自定义UserLocation注解

发布于 2024-10-21 05:53:30 字数 378 浏览 2 评论 0原文

我希望自定义 MKMapView userLocation 注释，以像官方地图应用程序一样绘制标题箭头。

我正在尝试在 viewForAnnotation: 中执行此操作，

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

    if ([annotation isKindOfClass:[MKUserLocation class]]) {

    }
 }

但我无法找到下一步要做什么来获取 UserLocation 的视图并对其进行自定义。

非常感谢...

I am looking to customize the MKMapView userLocation annotation, to draw a heading arrow like the official map app.

I am trying to do this in viewForAnnotation:

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

    if ([annotation isKindOfClass:[MKUserLocation class]]) {

    }
 }

but I am unable to find what to do next to get the view for UserLocation and customize it.

Many thanks...

我创建了 SVPulsingAnnotationView，它是 MKUserLocationView 的可自定义副本。

在此处输入图像描述

您可以像任何其他 MKAnnotationView 一样实例化它：

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
    if([annotation isKindOfClass:[MyAnnotationClass class]]) {
        static NSString *identifier = @"currentLocation";
        SVPulsingAnnotationView *pulsingView = (SVPulsingAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

        if(pulsingView == nil) {
            pulsingView = [[SVPulsingAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
            pulsingView.annotationColor = [UIColor colorWithRed:0.678431 green:0 blue:0 alpha:1];
        }

        pulsingView.canShowCallout = YES;
        return pulsingView;
    }

    return nil;
}

I created SVPulsingAnnotationView, a customizable replica of MKUserLocationView.

enter image description here

You instantiate it just like any other MKAnnotationView:

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
    if([annotation isKindOfClass:[MyAnnotationClass class]]) {
        static NSString *identifier = @"currentLocation";
        SVPulsingAnnotationView *pulsingView = (SVPulsingAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

        if(pulsingView == nil) {
            pulsingView = [[SVPulsingAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];
            pulsingView.annotationColor = [UIColor colorWithRed:0.678431 green:0 blue:0 alpha:1];
        }

        pulsingView.canShowCallout = YES;
        return pulsingView;
    }

    return nil;
}

默认用户位置标记的类（至少在 SDK 4.2 中）是 MKUserLocationView，但它不是公开的，因此您无法创建实例进行修改，否则会面临被应用商店拒绝的风险。您必须创建自己的 MKAnnotationView （或 MKAnnotationView 的子类）。
