I am learning Google Map SDK and I would like to allow the customer to change the map's type.

I thought that making a drop down list is helpful, but I see that Apple doesn't make a drop down list but it makes a picker instead.

What is the best user experience approach to allow users to selects the map's type?

I have chosen this:

![Map with button menu for type selection][1] 

Is this the best UX for this interaction? Is there another pattern that would be better?

### Edit ###
I see that storyboard just allows me to add one item bar at the right, so it seems that my choice is wrong.
