表视图与图像，慢负载和滚动 [英] Table View with Images, slow load and scroll

问题描述

我今天尝试了大约30个教程并且无法正常工作。

I tried impletmenting about 30 tutorials today and just cant get anything to work.

我的问题是我通过JSON文件加载我的信息，将数据添加到一个NSMutableArray，然后使用一个表来显示它。当我没有图像时，它工作正常，但当我的负载非常慢，滚动非常粘。在今天的调查结果之后，我有点了解它每次滚动都会重新加载图像，这就是为什么它的速度很慢。

My problem is that i load my information via a JSON file, add the data to a NSMutableArray, then use a table to display it all. It works fine when i dont have the images, but when i do its loads very slow and scrolls very sticky. I sorta understand after todays findings that its reloading the images every scroll which is why its slow.

有人可以将它分解并让我更容易解决这个问题？

Can someone please break it down and make it easier for me to solve this problem?

推荐答案

看看 Apple的LazyTableImages示例。基本上它归结为

a）重复使用表格单元格

a) reusing your table cells

b）仅加载当前可见的图像

b) only loading images that are currently visible
