获取有关地图视图选定注释的信息 [英] Get info on a mapview selected annotation

问题描述

我在地图视图和标注上有注释，每个标注上都有一个按钮.我需要做的是从这个标注中获取属性，即.标题，但记录这一行:

I have annotations on a mapview and a callout with a button on each. What I need to do is grab properties from this callout, ie. the title, but logging this line:

NSLog(@"%@", mapView.selectedAnnotations);

返回 这显然没有给我任何有用的信息......

returns <AddressAnnotation: 0x1bdc60> which obviously gives me no useful info...

我的问题是，如何访问选定注释标注的属性?

}
