I drop pins on an Apple map in my iPhone. How do I share that map with all the pins? I understand how to share individual pins. But if I have a map with a dozen pins, how can I share those dozen pins in one fell swoop? I mark a dozen locations, and I want someone to SEE those dozen locations on a map. On my own phone, I have a nice map with all the pins shown. But I want others to see that same map.
