ios - 具有巨大 contentSize 的 UIScrollView 滚动缓慢

Question

有没有办法配置 UIScrollView 以更快地滚动更大的 contentSizes？

Answer 1

The memory requirements of UIScrollView is very high in case you have large amount of data.

If you have very fixed amount of data, then UIScrollView is fine.

But if you want to manage large amount of data, I recommend that you use UITableView with customizations.

Because, in UIScrollView, you will have to know the size of your data and allocate memory based on that. Hence, the memory for content size of 50000 high is allocated and then you will be able to scroll.
