How do I add a UIActivityIndicatorView to footer of UICollectionView?

Question

How do I add a UIActivityIndicatorView to footer of UICollectionView in swift? For UITableView, it was just self.tableView.tableFootView = self.myActivityIndicatorView. Is this possible? If so, how?

Answer 1

Create view class and add activity indication in that view

Register this class as footer view class using:

registerClass(myFooterViewClass, forSupplementaryViewOfKind: UICollectionElementKindSectionFooter, withReuseIdentifier: "myFooterView")

Either set the headerReferenceSize on your collection view layout or implement

collectionView:layout:referenceSizeForHeaderInSection: in your delegate.

Return the footer view from the following method in your dataSource:

func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
let view = collectionView.dequeueReusableSupplementaryViewOfKind(UICollectionElementKindSectionFooter, withReuseIdentifier: "myFooterView", forIndexPath: indexPath)
// configure footer view
return view
}
