I have a map view with several annotations. The title of the annotation is the name of the business and the subtitle is the address. There is a detailDisclosure button on the annotation view that takes the user to a detail view for the selected annotation. The detail view has a UILabel with the text from the annotation title, a UILabel with the text from the annotation subtitle (the address), a button with the business website, a button with the business phone number, and lastly, a button for getting directions to the address. I'm wanting to take the address from the annotation subtitle so that when the user taps the Get Directions button, it opens up that in the Apple Maps app so they can get directions. My question is, how to I open the maps app with the address in the annotation subtitle?
