问题描述
您好，我已经创建了注解，完美出现在我的地图，但我不知道如何实现leftCalloutAccessoryView显示图像的任何指导，将是非常美联社preciated

解决方案
- （MKAnnotationView *）的MapView：（的MKMapView *）的MapView viewForAnnotation：（ID＆LT; MKAnnotation＆GT;）注释{静态的NSString *标识符= @MyLocation
如果（[注解isKindOfClass：[标类]）{ MKPinAnnotationView * annotationView =
（MKPinAnnotationView *）[myMapView dequeueReusableAnnotationViewWithIdentifier：符]; 如果（annotationView ==无）{
annotationView = [[MKPinAnnotationView页头]
initWithAnnotation：注释
reuseIdentifier：符];
}其他{
annotationView.annotation =注释;
} annotationView.enabled = YES;
annotationView.canShowCallout = YES;
*的UIImageView = imvLeft [[UIImageView的页头]初始化];
//设置图片
[annotationView setLeftCalloutAccessoryView：imvLeft]; 返回annotationView;
}回零;

Hi i have created annotations that show up perfectly on my map but i am not sure how to implement the leftCalloutAccessoryView to show images any guidance would be much appreciated
