Using Objective C and Xcode I have created a UICollectionView
with 10 sections and all works fine. Is there anyway to set the section to which is viewed when first shown? By default it shows sections 0-9, but I want it to start at section 5.
You can call scrollToItemAtIndexPath:atScrollPosition:animated:
in your viewDidAppear:
method.
You can hold a reference to the cell you want to scroll to, then use indexPathForCell:
to get the index path.
The following are the scroll positions you can choose from
UICollectionViewScrollPositionNone
UICollectionViewScrollPositionTop
UICollectionViewScrollPositionCenteredVertically
UICollectionViewScrollPositionBottom
UICollectionViewScrollPositionLeft
UICollectionViewScrollPositionCenteredHorizontally
UICollectionViewScrollPositionRight
In case you know where you want to scroll to in terms of an integer row and section, you can use those integers in the
NSIndexPath indexPathForItem:inSection:
method to create an NSIndexPath instead of keeping a reference to a cell and then calling indexPathForCell:. Also, you can move this code to the viewWillAppear: method if you want the scrolling to happen before the view is displayed.
