从相机或照片库附加图像缩略图

I have a static UITableView which on cell that looks like this:

我有一个静态的UITableView，它在单元格上看起来像这样：

Getting the Camera and Attach buttons to work was no problem. The user can take a picture or select one from their photo library.

让相机和附加按钮工作是没有问题的。用户可以拍照或从照片库中选择一张照片。

What I want to do 3 things:

我想做什么3件事：

1. Take the resulting image from the UIImagePickerController and add a thumbnail below the "Pictures" label.
2. 从UIImagePickerController获取生成的图像，并在“图片”标签下添加缩略图。
3. Do 1. for multiple images.
4. 做1.多个图像。
5. Have the option to remove an attached image.
6. 可以选择删除附加的图像。

My initial thought is to create a custom UIView that has a UIImageView and a delete button, and create one of these custom views for each image the user attaches and display them in a UICollectionView.

我最初的想法是创建一个具有UIImageView和删除按钮的自定义UIView，并为用户附加的每个图像创建其中一个自定义视图，并在UICollectionView中显示它们。

EDIT: Another option could be to insert a cell below the "Pictures" cell that contains a UIImageView, and enable editing for those cells so they can be removed.

编辑：另一个选项可能是在包含UIImageView的“图片”单元格下面插入一个单元格，并启用这些单元格的编辑，以便可以删除它们。

My question is this: is there a better way of doing this? Are there any online references I should be looking at? I've looked around for a while but haven't been able to find what I'm looking for.

我的问题是：有更好的方法吗？我应该看一下在线参考吗？我环顾了一会儿，但一直找不到我要找的东西。

Thanks!

谢谢！

I solved this by using a UICollectionView embedded in a UITableViewCell. The cell has a height of 0 to start and only shows when an image is added. Then, images are removed from the collection via UILongPressGesture.

我通过使用嵌入在UITableViewCell中的UICollectionView解决了这个问题。单元格的高度为0，仅在添加图像时显示。然后，通过UILongPressGesture从集合中删除图像。
