ZSPinAnnotation: Custom MKMapView pin images from UIColor

Wed, Dec. 7, 2011

Have you ever felt limited by the three Annotation pin colors that Apple provides with MapKit? Have you ever thought it was a pain to have to create custom images in photoshop every time you wanted to change the color? ZSPinAnnotation solves these problems by building the pin image on the fly. All you have to do is specify a UIColor and you get back a UIImage.

  • ZSImageView

If you want to create a ZSPinAnnotation you simply do the following:

UIImage *img = [ZSPinAnnotation pinAnnotationWithColor:[UIColor blueColor]];

The full implementation in mapView:viewForAnnotation:

- (MKAnnotationView *)mapView:(MKMapView *)mV viewForAnnotation:(id <MKAnnotation>)annotation {

    if(![annotation isKindOfClass:[Annotation class]]) // Don't mess user location
        return nil;

    static NSString *defaultPinID = @"StandardIdentifier";
    MKAnnotationView *pinView = (MKAnnotationView *)[self.mapView dequeueReusableAnnotationViewWithIdentifier:defaultPinID];
    if (pinView == nil){
        pinView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:defaultPinID] autorelease];
        //pinView.animatesDrop = YES;

    // Build our annotation
    if ([annotation isKindOfClass:[Annotation class]]) {
        Annotation *a = (Annotation *)annotation;
        pinView.image = [ZSPinAnnotation pinAnnotationWithColor:a.color];// ZSPinAnnotation Being Used
        pinView.annotation = a;
        pinView.enabled = YES;
        pinView.calloutOffset = CGPointMake(-11,0);

    pinView.canShowCallout = YES;

    return pinView;
