I have added a MKCircle as MKOverlay to my MKMapView. Also I added an UISlider to decide the radius of the circle. Unfortunately when using this it seems a bit "laggy", not smootly like I want it to be. Example: <a href="http://dl.dropbox.com/u/3077127/mkoverlayDelay.mov">http://dl.dropbox.com/u/3077127/mkoverlayDelay.mov</a> This is my code: <pre><code>- (void)addCircle { // draw the radius circle for the marker double radius = 2000.0; MKCircle *circle = [MKCircle circleWithCenterCoordinate:location radius:radius]; [circle setTitle:@"background"]; [mapView addOverlay:circle]; MKCircle *circleLine = [MKCircle circleWithCenterCoordinate:location radius:radius]; [circleLine setTitle:@"line"]; [mapView addOverlay:circleLine]; } - (void)addCircleWithRadius:(double)radius { MKCircle *circle = [MKCircle circleWithCenterCoordinate:location radius:radius]; [circle setTitle:@"background"]; [mapView addOverlay:circle]; MKCircle *circleLine = [MKCircle circleWithCenterCoordinate:location radius:radius]; [circleLine setTitle:@"line"]; [mapView addOverlay:circleLine]; } - (void)sliderChanged:(UISlider*)sender { [mapView removeOverlays:[mapView overlays]]; double radius = (sender.value * 100); [self addCircleWithRadius:radius]; } - (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay{ MKCircle *circle = overlay; MKCircleView *circleView = [[[MKCircleView alloc] initWithCircle:overlay] autorelease]; if ([circle.title isEqualToString:@"background"]) { circleView.fillColor = UIColorFromRGB(0x598DD3); circleView.alpha = 0.25; } else { circleView.strokeColor = UIColorFromRGB(0x5C8AC7); circleView.lineWidth = 2.0; } return circleView; } </code></pre> Does anybody have any suggestions on how I can smoothen this? Best regards, Paul Peelen

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
