如何使UICollectionview出现在特定部分

Question

My problem is that I couldn't find the way to appear specific section of UICollectionview.

For example, 5 sections exsisted and I want to make 3rd section appearing at the beginning.

But 1st section only appeared and could not find the method to choose the section I want to show.

If anyone knows the way to solve this problem, please tell me how to solve it.

Answer 1

If you don't want to modify your datamodel to order sections, and show '3rd section' as '1st section', then you can use

scrollToItemAtIndexPath:atScrollPosition:animated: on UICollectionView.

You can pass [NSIndexPath indexPathForItem:0 inSection:2] assuming you have items in that section.
