Uitableview mapView和UITable详细信息

尝试将注释的数据（名称、地址、电话、url、说明等）传递给带有表的DetailViewController。卡住了----请读代码。数据未通过Callout AccessoryTapped传递。帮忙

mapItem

存在于您的

gasButton

函数的for循环中，就我所见，没有其他地方。您已经创建了注释（

zip

）并将其添加到地图中。在

viewForAnnotation

中，将该注释作为参数提供给您，并要求您从中创建一个annotationView。在

calloutAccessoryControlTapped

中，您将看到一个annotationView，并被告知它已被点击。您需要沿着链返回到您的数据。从annotationView获取注释，从注释获取您的姓名

MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    NSLog(@"%@ - tapped", view.annotation.title);
}

在annotationView.title=annotation.title上的MKPinAnnotationView类型的对象上找不到“Property”title；行。对不起，我想你应该只设置注释的标题，这样你就可以去掉那行，我会调整我的答案。您可能还需要获得自己的MKPointAnnotation类，因为MKPointAnnotation没有

title

属性。一个快速的方法是使用以下答案中的代码：
