Remove a specific annotation from mapview

In my mapview I am creating pins like cafe, bar, night_club, and restaurant. How can I code to remove only the a specific point, cafe for example. I have used the code below to successfully remove ALL the annotations. I can't figure out how to delete one specific one (instead of all of them).

for (id<MKAnnotation> annotation in routeMapView.annotations) 
{
  if ([annotation isKindOfClass:[MapPoint class]]) 
  {
    [routeMapView removeAnnotation:index=annotation];
  }
}

You can use NSPredicate for the situation like 

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"pinName == %@",  @"Cafe"];
[myMapView removeAnnotations:[myMapView.annotations filteredArrayUsingPredicate:predicate]];

Above will remove all the annotations named cafe.

For more info you can see this answer Remove MKMapView Annotations with a certain pinColor?

    if ([[annotation title] isEqualToString:@"cafe"])
          [self.mapView removeAnnotation:annotation];
