ARCoreLocation is a lightweight and configurable iOS framework for displaying AR content at real-world coordinates.
• Easily create AR scenes that place AR objects in the real world
• Place AR objects at any geographic location without worrying about ARKit's implementation details
• Receive tap events on your AR content
• Receive events when AR content overlaps on-screen
Enter this in your Podfile:
pod 'ARCoreLocation', '~> 0.1.8'
Then run pod install. Remember to import ARCoreLocation in any file where you want to use it!
Create the ARLandmarker and add its view:
let landmarker = ARLandmarker(view: ARSKView(), scene: InteractiveScene(), locationManager: CLLocationManager())
landmarker.view.frame = self.view.bounds
landmarker.scene.size = self.view.bounds.size
self.view.addSubview(landmarker.view)Add Landmarks to the scene:
let landmarkLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 75, height: 20))
landmarkLabel.text = "Statue of Liberty"
let location = CLLocation(coordinate: CLLocationCoordinate2D(latitude: 40.689234, longitude: -74.044524), altitude: 30, horizontalAccuracy: 5, verticalAccuracy: 5, timestamp: Date())
landmarker.addLandmark(view: landmarkLabel, at: location, completion: nil)Get User Interaction events:
landmarker.delegate = self
...
extension ViewController: ARLandmarkerDelegate {
func landmarkDisplayer(_ landmarkDisplayer: ARLandmarker, didTap landmark: ARLandmark) {
...
}
func landmarkDisplayer(_ landmarkDisplayer: ARLandmarker, didFailWithError error: Error) -> Void {
...
}
}Use different strategies for overlapping landmarks:
landmarker.overlappingLandmarksStrategy = .showAll
landmarker.overlappingLandmarksStrategy = .showNearest
landmarker.overlappingLandmarksStrategy = .showFarthest
landmarker.overlappingLandmarksStrategy = .custom(callback: { (overlappingLandmarkGroups, notOverlappingLandmarks) in
// Check overlapping groups and react accordingly
})Request the landmarker to check for overlapping landmarks at a given interval:
// Check for overlaps every second
landmarker.beginEvaluatingOverlappingLandmarks(atInterval: 1)
...
landmarker.stopEvaluatingOverlappingLandmarks()Or check for overlapping landmarks immediately
// ... Or check immediately
landmarker.evaluateOverlappingLandmarks()
