Question
1) My annotation shows the title and subtitle of not. I have already tried a lot, but I can not.
2) If an annotation has been selected, the annotation will be centered in the middle of the window. So the map is moved. Any idea?
3) My Callout button does not work anymore, I've got the @ selector (openAnything) but I want to use this function is triggered - (void) mapView: (MKMapView *) mapView annotationView: (MKAnnotationView *) view calloutAccessoryControlTapped: (UIControl *) control {
Enough to ask, here's a video and some source code http://www.youtube.com/watch?v=Ur1aqeYEFHw&feature=youtube_gdata_player
Thanks

Solution 2
I fix the first one:
TAPPMapAnnotation *theAnnotation = (TAPPMapAnnotation *)self.annotation;
self.title = [[UILabel alloc]init];
self.title.font = [UIFont systemFontOfSize:12.0];
self.title.textColor = [UIColor whiteColor];
self.title.backgroundColor = [UIColor clearColor];
self.title.text = theAnnotation.title;
[...]
[self.theView addSubview:self.title];
OTHER TIPS
Your annotation class needs to have a subtitle attribute, yours has subTitle.
If calloutAccessoryControlTapped is not being called it is usually a sign your MKMapview's delegate has not been set. However you're only setting the accessory button when it gets selected. Do you have a good reason for that? Since the callout window won't be visible until it is selected, I would advise you to set the accessory button in viewForAnnotation and let it appear when the callout window does.
