我在地圖上有許多針腳,我想知道其視圖的左上角和右下角的座標以執行特定操作。獲取具有自定義視圖的註釋的邊界

這裏是我需要插入的代碼獲得特定註釋視圖的邊界代碼:

- (void)mapView:(MapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view { 
    if ([view.annotation isKindOfClass:[PlaceAnnotation class]]) { 
     PlaceAnnotationView *placeAnnotationView = (PlaceAnnotationView *)view; 
     // How to get the bounds of placeAnnotationView here? 
    } 
}
