推荐答案

我没有尝试过，但是请看

I've not tried this, but take a look at UIImagePickerControllerDelegate and the didFinishPickingMediaWithInfo method. I thought the actual path to the image was hidden, but the info Dictionary has a key called UIImagePickerControllerReferenceURL which looks like it might be a NSURL to the original image.

UIImagePickerControllerReferenceURL
The Assets Library URL for the original version of the picked item.
After the user edits a picked item—such as by cropping an image or trimming a movie—the URL continues to point to the original version of the picked item.
The value for this key is an NSURL object.
Available in iOS 4.1 and later.
Declared in UIImagePickerController.h

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
