相同的图像保存到两个单独的字段？

Question

我有 2 个图像视图（imageView 和 imageTwo）和四个按钮（每个图像视图的 takePhoto 和 selectPhoto）。点击每个按钮会在相应的图像视图中显示拍摄或选择的照片。伟大的。

但是，我正在尝试将拍摄的两张照片保存到我的数据库中。出于某种原因，拍摄的第一张照片保存到我的两个不同的数据库字段中（同一张照片出现在两个字段中，而不是每张不同的照片保存到两个单独的字段中）。也就是说，数据似乎正确保存（请参阅 XML 输出）。

这是为什么？请参阅下面的代码（对不起，冗长的帖子）。

viewcontroller.m

 //PHOTO ONE UPLOAD TAKE AND SELECT

    - (IBAction)selectPhoto:(id)sender {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        selectedImageView = self.imageView; // Add this

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

    - (IBAction)takePhoto:(id)sender {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        selectedImageView = self.imageView; // Add this

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

    - (IBAction)takePhotoTwo:(id)sender {

        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypeCamera;
        selectedImageView = self.imageTwo; // Add this

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

    }

    - (IBAction)selectPhotoTwo:(id)sender {

        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        selectedImageView = self.imageTwo; // Add this

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


    }

    - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
        UIImage *image = info[UIImagePickerControllerEditedImage];
        selectedImageView.image = image;

        [picker dismissViewControllerAnimated:YES completion:NULL];
    }


    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {

        [picker dismissViewControllerAnimated:YES completion:NULL];

    }


- (IBAction)saveButton:(id)sender {

我认为在第二个[DIOSFile fileSave... 中应该是secondfile 而不是file。
