我想通过使用本地镜像 URl 或 UIImage 来获取 PHAsset。如何使用 URl 或 UIImage 获取 PHAsset?
最佳答案
希望对你有帮助
//第1步:-导入照片
//step2:- 当您呈现 imagepicker Controller 时
if PHPhotoLibrary.authorizationStatus() == .authorized || PHPhotoLibrary.authorizationStatus() == .authorized{
PHPhotoLibrary.requestAuthorization { [weak self](_) in
// Present the UIImagePickerController
self?.present(self!.imagePicker, animated: true, completion: nil)
}
}
swift 4.2
extension ViewController:UIImagePickerControllerDelegate,UINavigationControllerDelegate {
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")
print(imagePath ?? "N0 imagePath found")
// 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 identifier = (info[UIImagePickerController.InfoKey.phAsset] as? PHAsset)?.localIdentifier
print(identifier)
self.dismiss(animated: true, completion: nil)
}
}
swift 3.0 和 swift4.0
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 identifier = (info[UIImagePickerControllerPHAsset] as? PHAsset)?. localIdentifier
print(identifier)
self.dismiss(animated: true, completion: nil)
}
谢谢
