MKZoomLevel

MKZoomLevel is an implementation of zoom level getter & setter for MKMapView that works exactly the same as the private _zoomLevel property without resetting the camera angle.

Features

• It returns exactly the same value as the internal _zoomLevel value as well as when the orientation or the angle is changed, which is in the MKMapView’s private API.
• It preserves the value of heading and pitch of the camera property for a new zoom level as they are, rather than resetting the camera angle.
• It returns the latest zoom level even when the animation of region change is not finished, in contrast with the camera property.

Usage

import MapKit
import MKZoomLevel

let mapView = MKMapView()

// Get the zoom level
mapView.zoomLevel

// Set the zoom level
mapView.zoomLevel = 16.0

// Set the zoom level with an animation
mapView.setZoomLevel(16.0, animated: true)
