How can I perform an action when I tap on a pin from MapKit? ios9, swift 2
<p>I've created a map with a ton of pins all over it, and tapping a pin pops up the default "bubble" and that's fine, for now.</p>

<p>What I would really like to do is not pop up the bubble at all and instead call a different function.  All of my searches have resulted in people wanting to create new custom annotations with different views and such, I just want to call a function and I'm not sure where I would try to call it from.  I'm pretty new to ios development and this seems like it should be pretty straightforward, but I'm finding this isn't usually the case.</p>
