MapKit is a powerful API available on iOS devices that makes it easy to display maps, mark locations, enhance with custom data and even draw routes or other shapes on top. To get started, download the starter project using the Download Materials button at the top or bottom of this tutorial. Open Main. Constrain the Map View to the super view not the Safe Areasetting 0 on all edges, so it stretches throughout the Safe Area of notched devices.
Build and run. You now have a fully zoomable and panable map showing the continent of your current location using Apple Maps!
And to do that, you need to get coding! Open ViewController. Go back to ViewController. When telling the map what to display, giving latitude and longitude is enough to center the map. But, you must also specify the rectangular region to display to get a correct zoom level.
The location argument is the center point. The region will have north-south and east-west spans based on a distance of regionRadiuswhich has a default of meters, a little more than half a mile, which works well for plotting the public artwork data in the GeoJSON file. The map view automatically transitions the current view to the desired region with a neat zoom animation, with no extra code required! MapKit is capable of constraining the user to pan and zoom the map over a specified area.
Simple MapView tutorial in Swift - MapKit
You can only pan the map view to see the northern, southern, eastern and westernmost edges of the island. MapKit uses an internal camera to determine where the point of view for the map is, how expansive the field of view is and to animate view movement.
When you specify a camera boundary with a center and a region rectangle, the camera center always stays within this region. It keeps them focused on the area you want them to see. A region size of 60, meters wide by 50, meters high keeps Oahu nicely constrained within the map view. The MapKit view camera keeps track of its distance from the view center when zooming in and out.Mix this with the MKMapViewDelegate and you have the ability to detect movement on the map, detect the state of the map such as failure loading it as well as several other items you can monitor.
We will also learn how to implement a delegate method and have the map move each time the user moves. The first step is to create a Single View Application by opening Xcode and creating the new project.
You can follow this tutorial if you are unsure how to create a new project. Make sure you select the language as Swift. You can uncheck unit tests, core data, and other optional extras. Navigate to Main. Drag out a Segment control and put that on the toolbar also. You might choose to use a flexible spacer between the button on the left and the segment to force them to the left and right edges of the toolbar.
Select the Segment View and change the segments to 3. Rename each segment as follows:. The next task is to drag a Map Kit View in to the view. I made mine fill the rest of the view above the toolbar. Open up the assistant editor which is found on the top toolbar over on the far right just second set of controls from the right.
Click the middle button which is 2 intersecting circles. Call it mapView and hit connect. Do the same from the current location and segment control. I dragged to just below viewDidLoad. Click connect when done. The reason we need to implement CoreLocation is so that we can use it to request authorisation for using the users location. Line 1 is where we request from the user permission to use their location.
As well as adding this line, you also need to add a key and description to the info. The key to add is:. Please use something better written if you publish your app. On the next lines of code we next set the mapType to. We also set. I added these just to demonstrate what can be enabled or disabled. You can make these changes in the storyboard as well by clicking on the map view and setting attributes that way. You can opt to set both in code as well as in the attributes section in the storyboard.
What you set in the storyboard will get overridden by what you set in code. When you run the app you will now see a map that shows your current location although you might not be able to see that on screen. You will need to scroll around to find the blue dot if your country is out of view. If you are using a simulator make sure you enable location in the Debug menu for the simulator. You should have 2 IBAction methods available in the class.
On line 2 we create an MKCoordinateSpain and initialise it with a latitude delta and a longitude delta of which I selected 0.
In practice, these numbers will vary a little specifically the longitude delta as you move north and south on the globe, although MapKit will still show a map even when the values are not quite right. The documentation tells us that 1 degree is approximately 69 miles for latitude meaning that 0.
Longitude delta is different because the higher up the globe you are, the smaller the distance between the degrees, so on the equator 0. You might also opt to make the deltas variables here so that you can pass numbers in such as a zoom level.
You might implement a slider and each time you tap current location it can take that slider value and pass that in to the lat and lng deltas to provide a zoom level.This guide assumes you are familiar with Swift and Xcode.
This is where you'll configure your Mapbox map.
MapKit Tutorial: Getting Started
Start by importing Mapbox. For now, define updateUIViewbut do not return anything. This will change when adding annotations and layers to the map.
In this step you'll prepare MapView to receive the values for several modifiers from ContentView where the actual values will be specified. These modifiers will determine the appearance of the map:. In ContentViewspecify MapView. Then, add and provide values for the centerCoordinate and zoomLevel modifiers. Next, you'll use State to add a single marker to the map that displays a callout when tapped.
The MapView updates the binding to match the visible page. Create an MGLPointAnnotation extension with a convenience initializer that will let you create an annotation using a title and a coordinate. In SwiftUI, a Coordinator can be used with delegates, data sources, and user events. Then, add another method called makeCoordinator to MapView to make the coordinator.
In the generated file ContentView. Build and run your application, and you will see a map centered on San Francisco with a marker at the center of the map. Inside the Coordinator class, implement the delegate methods to add a fill layer when the style finishes loading. Build the project, and you will see a map centered on San Francisco with a single marker and a filled rectangle on the map.

Using state variables and bindings to coordinate view updates.Adding a map to an iOS app is a widely spread feature. Maps make mobile apps more interactive and improve the user experience tremendously. In our mobile app templateswe integrated maps in several apps, such as in the Store LocatorClassifieds Appor Real Estate app.
In this MapKit tutorialwe are describing our experience of working with MapKit to help you learn how to add maps to your iOS app in Swift. Have you ever wanted to build a map in your phone application? Does it seem too difficult of a task? If so, then this article is for you.
Today, we will talk about MapKit. So, what exactly is MapKit? This class has all the features needed, such as map, satellite, or even the current location.
Hand gestures may be used on the screen to change the geographical region. We can also add annotationsphotostitles and mark specific locations on the map. Another great thing is that we can receive notifications such as changing the current location of the user or region of the map, through MKMapViewDelegate protocol.
Normally, we would have a starter project for you. Hopefully this will be an additional incentive for the readers to follow through. You can pin it to the edges of the screen or the safe area if you refer to this onefor simplicity by using auto layout constraints, of course.
Do not forget to import the MapKit library, so that the code compiles successfully. It looks like this:. BOOM, it looks awesome, right? MapKit has provided us with the map and now all we need to do is observe and handle the different events such as changing the current location or region etc.
Of course, if you do not do that, your application still works and the map still displays normally. But you have to do that because location information is one of the private information belonging to users. We have to ask their permissions before getting it. If you fail to acquire permissions first, you risk your app to crash. In the description part, you have to explain to the user why you need their permissions.
Step 3 : Check the Location Service.In iOS by using mapkit view we can create and access maps easily. By using map view in iOS we can show the standard map, satellite view map or both and it will allow users to add annotation or pin locations in map. By using maps in iOS we can display the route between source and destination places in our application.
We can access maps in our iOS applications by adding Mapkit reference. Once we open Xcode the welcome window will open like as shown below. The new Xcode window will contain several built-in app templates to implement common type of iOS apps like page based apps, tab-based apps, games, table-view apps, etc. These templates are having pre-configured interface and source code files. Enter your organization identifier in case if you don't have any organization identifier enter com.
Bundle Identifier : This value will generate automatically based on the values we entered in Product Name and Organization Identifier. Choose Devices options as Universal it means that one application is for all apple devices in case if you have any specific requirement to run app only for iPad then you can choose the iPad option to make your application restricted to run only on iPad devices.
This option is used for database operations. In case if you have any database related operations in your application select this option otherwise unselect the option. In case if you need unit tests for your application then select this option otherwise unselect it. Once we click on Next button new dialog will open in that we need to select the location to save our project. Once you select the location to save project then click on Create button like as shown below.
After click on Create button the Xcode will create and open a new project. In our project Main. Now in project select Main. Now select ViewController. Now we will add controls to our application for that open Object Library. The Object Library will appear at the bottom of Xcode in right side.
In case if you don't find Object library, click on the button which is at the third position from the left in the library selector bar like as shown below. As we discussed our user interface will be in Main. Now we will make connection between controls and ViewController.
Swift code for that click on assistant button overlap circle in Xcode toolbar right side corner like as shown below. To map the controls, press Ctrl button in keyboard and drag the MapView from canvas interface and drop into ViewController.
Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I thought of animating the value of the altitude of a MKMapCamera. Though, this doesn't zoom in or out the map. An MKMapCamera object describes a virtual camera that you use to define the appearance of the map.MKMapView - Строим маршрут из точки в точку
A camera object creates a virtual viewpoint above the map surface and affects how the map renders its tiles and other content.
These factors let you create a map view that is not just flat but offers a more 3D-like experience. Use the method setRegion:animated:. It takes an MKCoordinateRegion parameter. The region includes a span, which determines the range of north-to-south latitude shown on the screen. How are we doing? Please help us improve Stack Overflow. Take our short survey. Learn more.

So its likely not what you're looking for Apple Docs An MKMapCamera object describes a virtual camera that you use to define the appearance of the map.You use this class as-is to display map information and to manipulate the map contents from your application.
You can center the map on a given coordinate, specify the size of the area you want to display, and annotate the map with custom information. When you initialize a map view, you specify the initial region for that map to display by setting the region property of the map. A region is defined by a center point and a horizontal and vertical distance, referred to as the span. The span defines how much of the map should be visible and is also how you set the zoom level.
For example, specifying a large span results in the user seeing in a wide geographical area at a low zoom level, whereas specifying a small span results in a more narrow geographical area and a higher zoom level. In addition to setting the span programmatically, the MKMap View class supports many standard interactions for changing the position and zoom level of the map.
In particular, map views support flick and pinch gestures for scrolling around the map and zooming in and out. Support for these gestures is enabled by default but can also be disabled using the is Scroll Enabled and is Zoom Enabled properties.
You can also use projected map coordinates instead of regions to specify some values. When you project the curved surface of the globe onto a flat surface, you get a two-dimensional version of a map where longitude lines appear to be parallel.
The map view calls the methods of your custom delegate to let it know about changes in the map status and to coordinate the display of custom annotations, which are described in more detail in Annotating the Map.
The delegate object can be any object in your application as long as it conforms to the MKMap View Delegate protocol. In macOS Even if you specify a custom appearance, users can use the Maps app to force all maps to adopt a light appearance. Use the map view's effective Appearance property to determine the actual appearance of your map.
iOS Map View with Annotation
The MKMap View class supports the ability to annotate the map with custom information. Because a map may have large numbers of annotations, map views differentiate between the annotation objects used to manage the annotation data and the view objects for presenting that data on the map. An annotation object is any object that conforms to the MKAnnotation protocol.
This allows you to manipulate the annotation data directly but still make it available to the map view. The presentation of annotation objects on the screen is handled by an annotation viewwhich is an instance of the MKAnnotation View class.
An annotation view is responsible for presenting the annotation data in a way that makes sense. For example, the Maps application uses a marker icon to denote specific points of interest on a map.
You could also create annotation views that cover larger portions of the map. Because annotation views are needed only when they are onscreen, the MKMap View class provides a mechanism for queueing annotation views that are not in use.
Annotation views with a reuse identifier can be detached and queued internally by the map view when they move offscreen. This feature improves memory use by keeping only a small number of annotation views in memory at once and by recycling the views you do have. It also improves scrolling performance by alleviating the need to create new views while the map is scrolling. When configuring your map interface, you should add all of your annotation objects right away. The map view uses the coordinate data in each annotation object to determine when the corresponding annotation view needs to appear onscreen.
When an annotation moves onscreen, the map view asks its delegate to create a corresponding annotation view. If your application has different types of annotations, it can define different annotation view classes to represent each type.
