I have annotations on my mapview (self.friendsMapView) that should present a callout when tapped. Each annotation displays a title and a description (body). For some reason, no matter what I try, my callout will not show if my annotation is tapped. Am I missing something here?
A bit of background: I previously had two mapViews inside one ViewController (and, I had callouts working fine). However after I decided to remove one mapview (self.neighboursMapView) and its code, my callouts for self.friendsMapView seem to have stopped working.

[viewParamsFriend setValue:@"accepted_friends" forKey:@"view_name"];
[DIOSView viewGet:viewParamsFriend success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.friendData = [responseObject mutableCopy];
int index = 0;
for (NSMutableDictionary *multiplelocationsFriend in self.friendData) {
NSString *location = multiplelocationsFriend[@"address2"];
NSString *userNames = multiplelocationsFriend[@"first name"];
NSString *userBio = multiplelocationsFriend[@"body"];

Try viewForAnnotation method with following configuration.
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation{
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
if ([annotation isKindOfClass:[MKPointAnnotation class]])
{
MKAnnotationView *pinView = (MKAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:@"CustomPinAnnotationView"];
if (!pinView)
{
pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"CustomPinAnnotationView"];
pinView.canShowCallout = YES;
pinView.image = [UIImage imageNamed:@"annotation"];
pinView.calloutOffset = CGPointMake(0, 0);
UIImageView *iconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"annotation"]];
pinView.leftCalloutAccessoryView = iconView;
} else {
pinView.annotation = annotation;
}
return pinView;
}
return nil;
}
