问题:

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);

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

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

回答1:

This is how

 for (id annotation in mapView.annotations) {NSLog([annotation title]);}

回答2:

Here is what I did in the annotationviewClick function:

Hope this helps

-(IBAction) annotationViewClick:(id) sender{

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


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

}
