    <p>I have the following problem:</p> <p>I have a number of pins on my map. After touching one, a custom popup opens and displays information. This works perfect.</p> <p>My problem is, that if you select the same pin twice, the popups does not open, you have to touch another one or click some where in the map.</p> <p>My code is the following:</p> <pre><code>- (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(id &lt;MKAnnotation&gt;) annotation{ MKAnnotationView* annotationView = nil; CPPointOfInterest *myAnnotation = (CPPointOfInterest*) annotation; if ([myAnnotation isKindOfClass:[MKUserLocation class]] || myAnnotation.poi_id &lt;= 0) { return nil; } else { NSString* identifier = @"Pin"; MKPinAnnotationView* annView = (MKPinAnnotationView*)[mv_map dequeueReusableAnnotationViewWithIdentifier:identifier]; if(nil == annView) { annView = [[[MKPinAnnotationView alloc] initWithAnnotation:myAnnotation reuseIdentifier:identifier] autorelease]; } [annView addObserver:self forKeyPath:@"selected" options:NSKeyValueObservingOptionNew context:@"GMAP_ANNOTATION_SELECTED"]; if(self.nearest_poi == myAnnotation) { annView.pinColor = MKPinAnnotationColorGreen; } else { annView.pinColor = MKPinAnnotationColorRed; } annView.animatesDrop = YES; annotationView = annView; [annotationView setEnabled:YES]; [annotationView setCanShowCallout:NO]; return annotationView; } } </code></pre> <p>Observer:</p> <pre><code>- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context{ NSString *action = (NSString*)context; if([action isEqualToString:@"GMAP_ANNOTATION_SELECTED"]){ BOOL annotationAppeared = [[change valueForKey:@"new"] boolValue]; if (annotationAppeared) { // show popup } } } </code></pre> <p>I have also tried the didSelectAnnotationView methode, this also just works for the first click event.</p> <p>I have searched for several hours, but nothing to find... :/</p> <p>Does anybody knows a solution for my problem, please give me a hint...</p> <p>Thanks and greetings, Mathew</p>

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.
