I want to get geotag location from image which is selected from image picker. I am using this code
if picker.sourceType == UIImagePickerControllerSourceType.PhotoLibrary
{
if let currentLat = pickedLat as CLLocationDegrees?
{
self.latitude = pickedLat!
self.longitude = pickedLong!
}
else
{
var library = ALAssetsLibrary()
library.enumerateGroupsWithTypes(ALAssetsGroupAll, usingBlock: { (group, stop) -> Void in
if (group != nil) {
println("Group is not nil")
println(group.valueForProperty(ALAssetsGroupPropertyName))
group.enumerateAssetsUsingBlock { (asset, index, stop) in
if asset != nil
{
if let location: CLLocation = asset.valueForProperty(ALAssetPropertyLocation) as CLLocation!
{ let lat = location.coordinate.latitude
let long = location.coordinate.longitude
self.latitude = lat
self.longitude = lat
println(lat)
println(long)
}
}
}
} else
{
println("The group is empty!")
}
})
{ (error) -> Void in
println("problem loading albums: \(error)")
}
}
}
i want to know to covert this code in swift 3 .I am new in coding with swift 3 .It will be very helpful
After hours of searching i got my ans
import UIKit
import Photos
class ViewController: UIViewController,UIImagePickerControllerDelegate, UINavigationControllerDelegate {
@IBOutlet weak var imageView: UIImageView!
@IBOutlet weak var locationLabel: UILabel!
@IBOutlet weak var timeLabel: UILabel!
@IBOutlet weak var logi: UILabel!
@IBOutlet weak var lati: UILabel!
var lat = String()
var log = String()
var location = String()
var timeTaken = "Not Known"
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func imagegeo(_ sender: Any) {
let imagePicker = UIImagePickerController()
imagePicker.sourceType = .photoLibrary
imagePicker.delegate = self
present(imagePicker, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
var chosenImage:UIImage?
if let URL = info[UIImagePickerControllerReferenceURL] as? URL {
print("We got the URL 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]
location = String(describing: asset.location)
log = String(describing: asset.location?.coordinate.longitude)
lat = String(describing: asset.location?.coordinate.latitude)
timeTaken = (asset.creationDate?.description)!
print(log)
print(location)
print(lat)
}
}
if let editedImage = info[UIImagePickerControllerEditedImage] as? UIImage {
chosenImage = editedImage
} else if let selectedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
chosenImage = selectedImage
}
dismiss(animated: true) {
DispatchQueue.main.async {
self.imageView.image = chosenImage
self.timeLabel.text = self.timeTaken
self.locationLabel.text = self.location
self.lati.text = self.lat
self.logi.text = self.log
}
}
}
}
