First try this method just call this method when you remove annotation..

-(void) reloadMap
{
    [yourMapView setRegion:yourMapView.region animated:TRUE];
}

Option

Else just remove all annotation and add again with your array object.. remove annotation like this

 MKCoordinateRegion region;
 MKCoordinateSpan span;
 span.latitudeDelta=0.04;
 span.longitudeDelta=0.04;

region.span=span;  
region.center = currentLocation; 
[MymapView removeAnnotations:[MymapView annotations]];
MyAnnotation *ann = [[MyAnnotation alloc] init]; ///This is My Annotation class which i create for display detail of location
ann.title =MymapView.userLocation.title;  
ann.subtitle = MymapView.userLocation.subtitle;
ann.coordinate = currentLocation;
ann.annLocation=[NSString stringWithFormat:@"%f%f",currentLocation.longitude,currentLocation.latitude];
[MymapView addAnnotation:ann];

[MymapView setRegion:region animated:TRUE];
[MymapView regionThatFits:region];
