找到了一个答案，该答案将返回标注的编号:
Found an answer this will return annotation tapped number:
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
NSUInteger index = [mapView.annotations indexOfObject:view.annotation];
NSLog(@"index no %d",index);
}
上面的代码每次我们点击注释时都会生成随机索引号.
The above code will generate random index number each time we tap on annotation.
但是需要按如下所示重写代码
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view {
// Annotation is your custom class that holds information about the annotation
if ([view.annotation isKindOfClass:[Annotation class]]) {
Annotation *annot = view.annotation;
NSInteger index = [self.arrayOfAnnotations indexOfObject:annot];
}
}
