I have a UICollectionView
. The UICollectionView
's datasource
is a NSArray
of students (from CoreData
). I want the current student item be selected
/highlighted
.
How can I do this? I know there is a method:
- (void)selectItemAtIndexPath:(NSIndexPath *)indexPath
animated:(BOOL)animated
scrollPosition:(UICollectionViewScrollPosition)scrollPosition;
which takes as arguments an NSIndexPath
and UICollectionViewScrollPosition
.
I have the datasource (NSArray
of students populated from CoreData
) and the student object to be selected
.
So, how do I get the NSIndexPath
and UICollectionViewScrollPosition
?
Or is there any other way to highlight an item?
You can simply use this after [self.collectionView reloadData]
[self.collectionView
selectItemAtIndexPath:[NSIndexPath indexPathForItem:index inSection:0]
animated:YES
scrollPosition:UICollectionViewScrollPositionCenteredVertically];
where index
is the index number for the selected student.
