From the google map sdk / it appears at this moment v1.9 the only supported animations in using framed based images. If you're using mapkit - > you can simply use https://github.com/TransitApp/SVPulsingAnnotationView

From google's sdk -> ios sample

AnimatedCurrentLocationViewController.m

            NSMutableArray *frames = [NSMutableArray array];
            for (int i =0; i<146; i++) {
                NSString *img = [NSString stringWithFormat:@"pulse-%d",i];
                [frames addObject:[UIImage imageNamed:img]];
            }
           marker.icon = [UIImage animatedImageWithImages:frames duration:3];

On my branch of FlipBook https://github.com/johndpope/Flipbook I've rendered out the pulse animations in retina to a bunch of transparent png images. It maybe possible to further reduce these file sizes in photoshop. Granted this is not ideal and will cause your binary file size to be bloated but is passable.
