might make up several noncontiguous or adjoining shapes. You utilize annotations to represent details such as the user’s existing area, a particular address, or a single point of interest. You utilize overlays to provide more intricate details such as paths or traffic info, or the limits of locations such as parks, lakes, states, nations, or cities. Unlike generic subviews, overlays and annotations stay repaired to the map so that they move properly when the user zooms, pans, or scrolls. In a 3D map, annotations preserve their orientation, position, and size no matter how the map pitches or turns.

Map Kit separates the information related to an annotation or overlay from its visual discussion on the map. This separation enables the map to handle noticeable annotations and overlays far more effectively: You can include numerous annotations and overlays to a map and still anticipate sensible efficiency. It’s rather simple to include a map into your app utilizing MapKit. Exactly what if you desire to personalize the map or embellish offered by Apple with your own annotations and images? Fortunately, Apple offers and simple method to do this with Custom Overlay Views.

In this tutorial, you produce an app for the Six Flags Magic Mountain theme park. If you’re a roller rollercoaster fan in the LA location, you’ll make sure to value this app:] Simply consider exactly what a visitor to the park would have an interest in. Things like the area of particular destinations, paths to the numerous trips and roller rollercoasters, and the area of characters around the park. These are best prospects for custom-made overlay images– which’s precisely what you’ll be including this tutorial. Both poly lines and polygons are a variety of collaborates comprising a line. The distinction is the polygon closes the shapes and enables filling while the polyline does not Polylines are the method we mark paths on a map.

The Map Kit structure offers a user interface for embedding maps straight into your own windows and views. This structure likewise offers assistance for annotating the map, including overlays, and carrying out reverse-geocoding lookups to figure out placemark info for a provided map coordinate. MapKit is a cool API, comes with the iOS SDK, that enables you to show maps, browse through maps, include annotations for particular areas, include overlays on existing maps, and so on.

Overlay items are typically little information things that keep the points that specify the overlay and any other appropriate info, such as a title string. The map view keeps a recommendation to the overlay items you include to it and utilizes the information in those items to figure out when to show a matching view. Map Kit offers basic overlay renderers that can draw any shapes represented by the concrete overlay things. Just like annotations, you do not include overlay renderers straight to the map surface area. Rather, the delegate item supplies an overlay renderer when the map view requests for one, and the map view integrates the overlay into its nontransparent view hierarchy.

Normally, the collaborates of an overlay on the map never ever alter. It’s possible to produce draggable overlays, doing so is unusual. You would have to execute the code to track the dragging operation, and you need to upgrade the overlay coordinate points yourself. It’s crucial to keep in mind that the basic overlay renderers merely fill and stroke the shape represented by the overlay. Any subviews you include to an overlay are scaled along with the overlay itself and made to fit the zoom level of the map. Overlays and annotations stay repaired to the map so that they move properly when the user zooms, pans and scrolls. The finest method to reveal an area is to pin it on map.
