Answer 1

使用UIImagePickerController代表:

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

    NSDictionary *metadataDictionary = (NSDictionary *)[info valueForKey:UIImagePickerControllerMediaMetadata];
        // do something with the metadata

    NSLog(@"meta : %@ \n\n",metadataDictionary);
}
