By Justin Miller. Now your apps can plot directionsregions, user traces, and all sorts of other on-the-fly data right atop our beautiful basemaps, and alongside the existing point and marker annotation support. Grab the v0. We landed huge improvements to our already-solid labeling algorithms, increasing performance, labeling density and clarity, and speed. Maps look even better, perform faster, and bring more data to your apps.
Check out our build matrix on GitHub which runs every commit through a series of multi-platform tests. Retain control of your data and gain intelligence about your users. Our mobile analytics keep data secure and anonymized, but give you unparalleled access to app and location insights every day. Mapbox Mobile is open source and brings together many pieces of our stack:. Plus hundreds of other components across many repositories working on the server-side to display beautiful, optimized, and always up-to-date maps.
And because Mapbox Mobile is open, we provide a version of the library with debug symbols intact for symbolication in your own projects. We now default to installing the version without symbols for a 10x reduction in library install size. As before, Mapbox Mobile increases your app size by only a megabyte. Mapbox Mobile is free to use in your apps for up to 50, monthly active users.

If you read part 1 of this tutorial, you should already be familiar with the basics of MapKit. You can get started by downloading the starter project from GitHub. In the last part of this tutorial series, we worked with overlays in MapKit.
We rendered overlays on top of the map to show users key areas that we wanted to highlight. By combining annotations and overlays, you can really easily display rich data on top of a map. In our last example, we rendered a circle. How about we start with the basics to create a polylineor a line made up of multiple different points joined together?
To keep things simple, we will draw a polyline between all of the cities we used in the last example. MKPolyline is a class that can be used to represent a connected sequence of line segments.
You can create a polyline by constructing a MKPolyline object with a series of end-points like this:. First, head to ViewController. Then, move to the addAnnotations method, where we are adding circular overlays to mapView. Go ahead and add the following to the end of the method:. Here please take a special note of the way we pass in the coordinates parameter to the initializer for MKPolyline. We cannot provide our coordinates as an array directly because Swift is unable to bridge this array to its Objective C type, as there is no Objective C type for an array of C structs.
Additionally, you need to provide the count of the array you pass in so that Objective C can determine how many objects have been provided. Now that we have provided the polyline overlay to MapKit, we need to tell MapKit how to render the overlay.
Remember how we provided an MKCircleRenderer when we wanted to render a circle? The first thing we need to do is modify this method so that it can check what kind of overlay is being rendered and respond appropriately. Easy, right? MKPolylineRenderer is self explanatory for those who have worked with MKCircle renderer, as the setup process is identical.
Build and run the app, and voila! MapKit also provides us with a class for rendering polygons. Currently, our addAnnotations function is responsible for adding annotations and a polyline. Finally, modify the viewDidLoad method to call all of our overlay methods.
Your viewDidLoad method should look like this:. Okay, it is time to implement the addPolygon method. To draw a polygon on map, you just need a few lines of code. Insert the following code in the method:.The inspiration for this stems from the development of a new product at door2doorwhere we decided to use polylines with this design to communicate walking paths to the user.
So surely Google would include the ability to stylise a polyline in this way in their SDK, right? This styles the polyline so that it consists of shorter lines separated by spaces. Instead of spaced-out lines, we want spaced-out dots, or circles. In order to achieve this, we have to abandon the idea that we can somehow customise a GMSPolyline in this fashion, and instead turn to another class: GMSCircle.
Instead of directly putting it on the map, we want to first transform it into an array of GMSCircle objects. Here is the solution I came up with to do this:. We calculate the distance between these, and use that to work out the change in latitude and longitude intervalLatIncrement and intervalLngIncrement for 1 metre along the path.
We then iterate through the intervals along the distance between the two locations, and at each interval work out a coordinate circleCoordinate. Now to draw some circles! If they are closer together than our intervalDistanceIncrementthat being the minimum distance we want between each circle, then we continue the execution of the loop. Nothing too crazy, eh?
Maps and location for developers
You may be wondering what circleRadiusScale is, and why we need it when setting a radius for our circle. This is to ensure that our circles appear the same size on the map regardless of the zoom level of the map, that being how far in or out the user has zoomed on the map. This is easily calculated by dividing 1 by the number of points on the screen that represent 1 metre.
As we are making use of this scale, we need to remove and then recreate the polyline every time the position of the map is changed. Putting the code we wrote above in a function and calling that function from this GMSMapViewDelegate callback ensures we do exactly that.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. With advantage of MKGeodesicPolyline, the code above works perfect only for a short distance! If the given locations quit far like from USA to Asia, it will create an unwanted horizon strange line above the curve.
This is due to the fact the the line cross the international date change line so it's wrapping all the way around. To avoid that you can add or subtract from your longitude to fix it. Learn more.

I want to clear this polyline and redraw with different coordinates. I tried removeAnnotation method but it didn't help. I found solution. We can reach source with identifier like self. I was dealing with almost the same problem.
I needed to clean the map and add another polyline. My code to create a polyline. So, i found out there is no easy method to remove a polyline. I created a random string to add to the identifier of the polyline everytime it creates a new one to solve this problem.
