Swift 4.0 and iOS 11.2.1
I have an app that has the option to take a photo or grab one from the phones gallery.
If I selsct one from the gallery I can see the GPS data in the info[UIImagePickerControllerReferenceURL], but when I save it to the apps documents folder it loses the GPS data.
If I take a photo from within the app the info[UIImagePickerControllerReferenceURL] is nil?
My goal is to save the photo whether from image gallery or taken from within the app to the app document folder and have it retain the gps data.
@IBAction func takePicture(_ sender: Any)
{
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera)
{
imgPicker.sourceType = .camera
imgPicker.showsCameraControls = true
self.present(imgPicker, animated: true, completion: nil)
}
}
@IBAction func getPicture(_ sender: Any)
{
imgPicker.sourceType = .photoLibrary
imgPicker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
present(imgPicker, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
/
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
let scale = 1024 / image.size.height
let newWidth = image.size.width * scale
UIGraphicsBeginImageContext(CGSize(width: newWidth, height: 1024))
image.draw(in: CGRect(x: 0, y: 0, width: newWidth, height: 1024))
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
if let image = newImage
{
viewModel.images.append(RestCalls.LocalImage(lclID: 0,
pickupDeliveryID: 0,
image: image,
path: "",
uploaded: 0,
invoiceID: 0,
isSignature: 0,
isDelivery: 0,
isCustomerPickup: 0))
viewModel.createImages()
viewModel.getImages()
collectionView.reloadData()
}
//Here is where I am able to print it to the console, it just doesn't stay with the photo
if let URL = info["UIImagePickerControllerReferenceURL"] as? URL
{
let opts = PHFetchOptions()
opts.fetchLimit = 1
let assets = PHAsset.fetchAssets(withALAssetURLs: [URL], options: opts)
print(assets)
for assetIndex in 0..<assets.count
{
let asset = assets[assetIndex]
let location = String(describing: asset.location)
let log = String(describing: asset.location?.coordinate.longitude)
let lat = String(describing: asset.location?.coordinate.latitude)
let timeTaken = (asset.creationDate?.description)!
print("Longitude: \(log)")
print("Latitude: \(lat)")
print("Time: \(timeTaken)")
}
}
