添加手势事件

- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation
{
    if ([annotation isKindOfClass:[MAPointAnnotation class]]) {
        NSString *pointReuseIndetifier = @"pointReuseIndetifier";
        
        MAAnnotationView *annotationView = (MAAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:pointReuseIndetifier];
        if(!annotationView) {
            annotationView = [[MAAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pointReuseIndetifier];
            [annotationView addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onClick:)]];
        }
        
        annotationView.image = [UIImage imageNamed:@"userPosition"];
        annotationView.canShowCallout = YES;
        return annotationView;
    }
    
    return nil;
}

swift

    func mapView(_ mapView: MAMapView!, viewFor annotation: MAAnnotation!) -> MAAnnotationView! {
        if (annotation.isKind(of: MAPointAnnotation.self))
        {
            let pointReuseIndetifier = "myReuseIndetifier"
            var annotationView:MAAnnotationView! = mapView.dequeueReusableAnnotationView(withIdentifier: pointReuseIndetifier)
            if (annotationView == nil)
            {
                annotationView =  MAAnnotationView.init(annotation: annotation, reuseIdentifier: pointReuseIndetifier)
                annotationView.addGestureRecognizer(UITapGestureRecognizer.init(target: self, action: #selector(self.onClick(tapGesture:))))
                let imge  =  UIImage.init(named: "userPosition")
                annotationView?.image =  imge
            }
            
            annotationView?.canShowCallout              = true
            
            return annotationView;
        }
        
        return nil;
    }
