获取一个图形页面选择的注释信息 [英] Get info on a mapview selected annotation

问题描述

我有一个图形页面，并在每一个按钮标注注解。我需要做的就是从这个标注，即抢属性。头衔，但记录此行：

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);

收益＆LT; AddressAnnotation：0x1bdc60＆GT; 这显然给我任何有用的信息...

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

我的问题是，我怎么能访问选择的注释标注的属性？

My question is, how can I access the properties of a selected annotation callout?

推荐答案

下面是我在annotationviewClick功能所做的：

Here is what I did in the annotationviewClick function:

希望这有助于

-(IBAction) annotationViewClick:(id) sender{

    [self.view addSubview:LoadingView];
    Annotation *ann = [myMap.selectedAnnotations objectAtIndex:([myMap.selectedAnnotations count]-1)];


    NSLog(@"Selected:%@", [ann tag]);

}
