How to Hide MKAnnotationView Callout?

Question

i'm trying to hide an AnnotationView without touching the pin, is the possible? Thanks!

for (id currentAnnotation in self.mapView.annotations) {        
if ([currentAnnotation isKindOfClass:[MyAnnotation class]]) { 
    } 
}

Answer 1

Do you just want to make the callout bubble go away but keep the pin?
If yes, then do this:

for (id currentAnnotation in self.mapView.annotations) {        
    if ([currentAnnotation isKindOfClass:[MyAnnotation class]]) { 
        [self.mapView deselectAnnotation:currentAnnotation animated:YES];
    } 
}
