iOS 的 ImagePickerController

Question

我正在尝试 select 设备照片库中的图片。到目前为止，这是我的代码。我正在学习一个教程，它应该可以工作，但我收到一个错误：

"Use of undeclared identifier info", on the second method, line 3.

我做错了什么？

   - (IBAction)selectPicturePressed:(UIButton *)sender {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = NO;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

        [self presentViewController:picker animated:YES completion:NULL];

    }
    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)img editingInfo:(NSDictionary *)editInfo
    {
        UIImage *chosenImage  = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
        self.imgToUpload.image = chosenImage;

        [picker dismissViewControllerAnimated:YES completion:NULL];
    }
    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

        [picker dismissViewControllerAnimated:YES completion:NULL];

    }

Answer 1

将 info 更改为 editInfo 即可解决。
