How do you always show the annotation callouts, i.e. don’t hide them when you tab the map view?
The callout is shown when an
MKAnnotationViewis selected and the view’scanShowCalloutproperty is set toYES.It is then hidden when that
MKAnnotationViewis deselected. This occurs by tapping another annotation view, or by tapping outside of the currently selected annotation view.As the delegate of
MKMapView(conforming toMKMapViewDelegate), you are told when an annotation view is selected and deselected, but it’s too late to do anything about it.If you want to not deselect an annotation view, you should subclass
MKAnnotationViewand override thesetSelected:animated:method and stop the annotation view from being deselected.
