I tried to keep this project as simple as possible so that you can focus on the map component, because there was a lot to learn:
CLLocationCoordinate2D and so on, and all must be used before you get a finished product.
Again, we've only scratched the surface of what maps can do in iOS, but that just gives you more room to extend the app yourself!
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try your new knowledge to make sure you fully understand what’s going on:
dequeueReusableAnnotationView()so that it's an
MKPinAnnotationView. Once that’s done, change the
pinTintColorproperty to your favorite
UIAlertControllerthat lets users specify how they want to view the map. There's a
mapTypeproperty that draws the maps in different ways. For example,
.satellitegives a satellite view of the terrain.
One of the most effective motivators of success is sharing your progress with other people – when you tell folks what you're doing and what you've learned, it encourages you to come back for more, which in turn will help you reach your app development goals faster.
So, now that you've done all the hard work it's time to share your success: tell folks that you've completed this project, either by clicking the button below to start composing a tweet, or by writing your own message from scratch. This will definitely encourage you to keep learning, but it will also help other folks discover my work – thank you!
