I need to delete the image from PhotoLibrary. I am using UIImagePickerController in my application to pick up the image. I need to delete this image from iOS PhotoLibrary after i use it in my application.

                imagePicker.delegate = self
                imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary;
                imagePicker.allowsEditing = false

            }


// MARK:- UIImagePickerControllerDelegate
func imagePickerController(picker: UIImagePickerController, didFinishPickingImage image: UIImage!, editingInfo: [NSObject : AnyObject]!) {
    pickedImage = image
    saveImageToDisk(pickedImage)
/*
I need the logic to delete this image from PhotoLibrary here.
*/
    self.dismissViewControllerAnimated(true, completion: nil)

推荐答案

只需添加到上面，对于Swift 3.0，它对我有用.

Just to add to the above,For swift 3.0 this worked for me.

PHPhotoLibrary.shared().performChanges({
                let imageAssetToDelete = PHAsset.fetchAssets(withALAssetURLs: imageUrls as! [URL], options: nil)
                PHAssetChangeRequest.deleteAssets(imageAssetToDelete)
            }, completionHandler: {success, error in
                print(success ? "Success" : error )
            })
