[英]How obtain GPS data from a photo
我已经尝试了几天,找到了一种从照片库中的照片获取GPS位置的方法。 我正在使用UIImagePicker来获取照片,但是在互联网上发布的任何一种解决方案似乎都没有用。 我知道我应该将UIImage转换为PHAsset,但是到处都有人在使用不赞成使用的方法fetchAssets(withALAssetURLs: [URL], options: PHFetchOptions?)
。 有什么办法可以做到这一点? 非常感谢你
我希望这能帮到您:-
//step1:- import Photos
//step2:- when you presenting imagepicker controller
if PHPhotoLibrary.authorizationStatus() == .authorized || PHPhotoLibrary.authorizationStatus() == .authorized{
PHPhotoLibrary.requestAuthorization { [weak self](_) in
// Present the UIImagePickerController
self?.present(self!.imagePicker, animated: true, completion: nil)
}
}
//step3:-
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
//obtaining saving path
let fileManager = FileManager.default
let documentsPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first
let imagePath = documentsPath?.appendingPathComponent("image.jpg")
// extract image from the picker and save it
if let pickedImage = info[UIImagePickerControllerOriginalImage] as? UIImage {
let data = UIImageJPEGRepresentation(pickedImage, 0.75)
data.write(toFile: localPath!, atomically: true)
}
let coordinate = (info[UIImagePickerControllerPHAsset] as? PHAsset)?.location?.coordinate
print(coordinate?.latitude ?? "No latitude found")
print(coordinate?.longitude ?? "No longitude found")
self.dismiss(animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
//obtaining saving path
let fileManager = FileManager.default
let documentsPath = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first
let imagePath = documentsPath?.appendingPathComponent("image.jpg")
// extract image from the picker and save it
if let pickedImage = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
let imageData = pickedImage.jpegData(compressionQuality: 0.75)
try! imageData?.write(to: imagePath!)
}
let coordinate = (info[UIImagePickerController.InfoKey.phAsset] as? PHAsset)?.location?.coordinate
print(coordinate?.latitude ?? "No latitude found")
print(coordinate?.longitude ?? "No longitude found")
self.dismiss(animated: true, completion: nil)
}
谢谢
