獨立操作來映射疊加-xcode

Question

如何添加獨立操作來映射疊加？例如，看我的代碼：我不確定是否應該使用循環或if語句。如果我使用If語句應該如何？預先感謝您..

- (void)configureOverlay { 
if (self.location) { 
    [self.mapView removeAnnotations:[self.mapView annotations]];   
    [self.mapView removeOverlays:[self.mapView overlays]]; 

    radiusSmall = 100; 

     circleOverlaySmall *overlaysmall = [[circleOverlaySmall alloc] initWithCoordinate:self.location.coordinate radius:radiusSmall]; 
    [self.mapView addOverlay:overlaysmall]; 
    [self updateSmall]; <--this action called 

      CircleOverlay *overlay = [[CircleOverlay alloc] initWithCoordinate:self.location.coordinate radius:self.radius]; 
    [self.mapView addOverlay:overlay]; 

    GeoQueryAnnotation *annotation = [[GeoQueryAnnotation alloc] initWithCoordinate:self.location.coordinate radius:self.radius]; 
    [self.mapView addAnnotation:annotation]; 

    [self updateLocations]; <--this action called 

} 
}

只是拖動[self uploadSmall];在[self updateLocations]下面;
