Once again, this post has been updated.

I was not completely satisfied with my prior solution to custom callout bubble in MKMapView due a drawback.

One drawback is that if you click an annotation in the TouchView it is not propagated down to the MKMapView which makes pinch zoom bit more tricky if you have many annotations. Someone out there might have a good solution for it?

Fortunately I figured out a new solution for the problem! A much more simple solution too.

It is a combination of the property change listener solution and moving the calloutOffset off the display.

Set the calloutOffset off the display and add an observer to the selected-property.
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id )annotation {

MKAnnotationView* annotationView = nil;

MyAnnotation *myAnnotation = (MyAnnotation*) annotation;
NSString* identifier = @"Pin";
MKPinAnnotationView* annView = (MKPinAnnotationView*)[self.mapView dequeueReusableAnnotationViewWithIdentifier:identifier];

if(nil == annView) {
annView = [[[MKPinAnnotationView alloc] initWithAnnotation:myAnnotation reuseIdentifier:identifier] autorelease];
}
//Add an observer for the selected-property on the MKAnnotationView. Delegate to self.
[annView addObserver:self
forKeyPath:@"selected"
options:NSKeyValueObservingOptionNew
context:GMAP_ANNOTATION_SELECTED];

[annView setPinColor:MKPinAnnotationColorGreen];

return annotationView;
}

Implement the observeValueForKeyPath method. It will be triggered when the property is selected or deselected.

- (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) {
[self showAnnotation:((MyAnnotationView*) object).annotation];
}
else {
NSLog(@"annotation deselected %@", ((MyAnnotationView*) object).annotation.title);
[self hideAnnotation];
}
}
}


Take a look at my new example (with standard MKPinAnnotationView) or with custom annotation view.
