这是我的代码：

-(void) takePhoto
{
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    //imagePickerController.editing = YES;
    imagePickerController.allowsEditing=YES;
    imagePickerController.delegate = self;

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

#pragma mark - Image picker delegate methods
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:NO completion:nil];

    [self.Picture setImage:[info objectForKey:UIImagePickerControllerOriginalImage]];


}

我已经实施了代表

UINavigationControllerDelegate,UIImagePickerControllerDelegate

拍摄了图像，我可以看到移动和缩放框，但是当我移动它时，框会返回到初始位置 - 就像它弹回一样。

这是为什么？

看起来这是因为您正在请求UIImagePickerControllerOriginalImage，根据文档，这将返回“用户选择的原始、未裁剪的图像”。

尝试将其更改为UIImagePickerControllerEditedImage.

编辑：实际上，如果问题发生在选择器本身，则在重新阅读问题几次后，这可能无济于事。
