推荐答案

滚动演示对于大型图像集不起作用，但是一些小的调整可以很容易解决。诀窍是使用UIScrollView委托方法按需加载图像，然后在它们消失后卸载它们。为了获得不错的性能，您需要加载中央图像和两侧的一个或两个 - 这意味着您可以扩展该设计以支持任意数量的图像，但内存中的图像仍然不会超过3-5。时间。

The "Scrolling" demo won't work as-is for a large image set, but some minor adjustments can easily fix that. The trick is to use UIScrollView delegate methods to load images on demand and then unload them after they disappear. For decent performance you'd want the central image and one or two on either side to be loaded-- meaning that you can extend that design to support as many images as you like but still never have more than 3-5 in memory at a time.

您发布的Stackoverflow链接实际上并未提及表格视图，因此我不确定您的方法是什么。如果通过section caption指的是section section和/或footer text，那么就不要提供任何内容。表视图没有默认值，所以如果你没有给表视图一个，那么它就不会显示一个。

The Stackoverflow link you post doesn't actually mention table views, so I'm not sure what approach you have in mind there. If by "section caption" you're referring to section header and/or footer text, then just don't provide any. Table views don't have a default for this, so if you don't give one to a table view then it won't show one.
