iOS MapKit自定义PIN

如何在地图中显示图像而不是图钉。到目前为止，我只能在水龙头上添加插脚。.m的示例代码将非常有用，因为我对iOS编程还是新手。

    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];

编辑：

我可以向您解释有关

MKAnnotationView

的所有内容，但我想您会发现，苹果提供的文档比任何其他来源的文档都要好得多。检查链接中的概述部分

转到Xcode的组织者，然后转到文档并搜索天气图，它显示了地图示例，并在注释处包含图像。

它可以工作。谢谢请简要说明传递的参数以及注释标识符是什么？这类似于.net的标记属性吗？在我的要求中，我没有使用“someImage.png”，而是使用UIView并使用[annotationView addSubView:myView]。工作正常。但不在点击时调用“didSelectAnnotationView”。有什么问题吗？可能是您需要禁用该视图的用户交互。为什么要将标题设置为UIButtonTypedTailExposition类型的按钮？这有什么意义吗？如果您想用自定义点设置用户的位置，请从上面注释这些行<代码>如果（[annotation isKindOfClass:[MKUserLocation class]]）返回nil一个小搜索会有很大的帮助：）并且：在发布一个长代码片段之前添加一些描述。
