UIRefreshControl on UICollectionView only works if the collection fills the height of the container

Question

I\'m trying to add a UIRefreshControl to a UICollectionView, but the problem is that the refresh control does not appear unless the collection view

Answer 1

You must check in api call if collection view is in refreshing state then end refreshing to dismiss refreshing control.

private let refreshControl = UIRefreshControl()
 refreshControl.tintColor = .white
 refreshControl.addTarget(self, action: #selector(refreshData), for: .valueChanged)
 collectionView.addSubview(refreshControl)
 @objc func refreshData() {
    // API Call
 }
// Disable refresh control if already refreshing 
if refreshControl.isRefreshing {
    refreshControl.endRefreshing()
}
