Clustering annotations won't work

Question

Today i started to use ADClusterMapView ( https://github.com/applidium/ADClusterMapView ) and studied the example project... so i decided to add the content to my project... every thing was OK no red errors... the simulator turned on and posted a thread... I'm trying to figure out the problem for hours... so maybe you have idea where the problem is...

-(void)viewDidLoad {

   [ADClusterMapView class];
   NSArray* airports = [Airport allAirports];
   [mapView setAnnotations:airports];
   [mapView setVisibleMapRect:MKMapRectWorld];
}

-(MKAnnotationView*)mapView:(MKMapView *)aMapView viewForAnnotation:(id<MKAnnotation>)annotation {
static NSString* reuseIdentifier = @"airportAnnotation";

    if ([annotation isKindOfClass:[Airport class]]) {
        MKAnnotationView* annotationView = [mapView dequeueReusableAnnotationViewWithIdentifier:reuseIdentifier];
        if (!annotationView) {
            annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:reuseIdentifier] autorelease];
            annotationView.canShowCallout = YES;
    }
        annotationView.image = ((Airport*)annotation).icon;
        return annotationView;
    }
}


- (MKAnnotationView *)mapView:(ADClusterMapView *)aMapView viewForClusterAnnotation:(id<MKAnnotation>)annotation {
MKAnnotationView * annotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:@"ADMapCluster"];
if (!annotationView) {
    annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation
                                            reuseIdentifier:@"ADMapCluster"]
               autorelease];
    annotationView.image = [UIImage imageNamed:@"circle.png"];
    annotationView.canShowCallout = YES;
}
else {
    annotationView.annotation = annotation;
}
    return annotationView;
}

the Error in debuger was:

Airports[3489:c07] -[MKMapView setAnnotations:]: unrecognized selector sent to instance 0x8095570 Airports[3489:c07] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MKMapView setAnnotations:]: unrecognized selector sent to instance 0x8095570' * First throw call stack: (0x1945012 0x1275e7e 0x19d04bd 0x1934bbc 0x193494e 0x2b6e 0x29e817 0x29e882 0x1eda25 0x1ee311 0x28db 0x1ba7b7 0x1bada7 0x1bbfab 0x1cd315 0x1ce24b 0x1bfcf8 0x18a0df9 0x18a0ad0 0x18babf5 0x18ba962 0x18ebbb6 0x18eaf44 0x18eae1b 0x1bb7da 0x1bd65c 0x282d 0x2765) libc++abi.dylib: terminate called throwing an exception sharedlibrary apply-load-rules all Current language: auto; currently objective-c

At first, I tried myself to use ADClusterMapView but I finally ended up building my own simple clustering system, inspired by WWDC 2011 presentation. If you want to have a look, check my answer http://stackoverflow.com/a/20271466/1394534. There are both codes for Google SDK and MapKit — Aurelien Porte, Dec 26 '13 at 10:28
Than you! Do you have a example project in github or something like that? — ABundzs, Dec 27 '13 at 19:01

[mapView setAnnotations:airports]; seems to be the problem. From doc, only addAnnotations:, addAnnotation: and their remove equivalent are available. Plus, annotations property is readonly so setAnnotations crashes, normal

Apparently, it's happening because you forgot to change the Custom Class on Identity Inspector (right side Utilities). Simply set the value to ADClusterMapView.
