推荐答案

我建议您使用开源的网格视图控件.您可以在GitHub中找到它们.例如， BDDynamicGridViewController 很有趣.但这不是唯一的选择.还有 AQGridView .

I recommend you to use an open-source grid-view control. You can find them in GitHub. For instance, BDDynamicGridViewController is interesting. But it is not the only option. There is also AQGridView.

此外，还有一个流行的开源库，名为 Three20 ，它已经进行了升级，叫做雨云.该库具有用于显示照片网格的自定义控件.您可以将其用于显示视频缩略图网格.例如，尝试

Also, there is a popular open-source library, called Three20 and it has it's upgrade, called Nimbus. This library has a custom control for displaying photos grid. You can use the same for displaying video thumbnails grid. For instance, try this.

在设法使用或创建Grid视图控件后，将需要视频的缩略图生成器.为此，请使用本主题 .

After you will manage to use or create Grid view control, you will need thumbnail generator for the videos. Use this topic for that purpose.
