Disabling scrollViewDidScroll method when searching in UITableView in Swift - ios

Question

I implemented scrollViewDidScroll in order to update UITableView when tableView did scroll to bottom. and adding 10 new elements to it.
There is a UISearchbar in UITableView too. when I search something, scrolling might be needed. but I don't want scrollViewDidScroll to be executed in this situation.
override func scrollViewDidScroll(scrollView: UIScrollView) {
let height = scrollView.frame.size.height
let contentYoffset = scrollView.contentOffset.y
let distanceFromBottom = scrollView.contentSize.height - contentYoffset
if distanceFromBottom < height {
print(" you reached end of the table")
self.fetchOffset += 10
// changing fillteredPosts. updating tableView.
}
}
func updateSearchResultsForSearchController(searchController: UISearchController) {
filteredPosts.removeAll()
let searchText = searchController.searchBar.text
if let searchString = searchText, let searchInt = Int(searchString) {
for post in originalAllPosts {
if post.userId == searchInt {
filteredPosts.append(post)
}
}
}
tableView.reloadData()
}

Assuming you are performing search for every single character that is entered
override func scrollViewDidScroll(scrollView: UIScrollView) {
if searchController.searchBar.text.isEmpty {
let height = scrollView.frame.size.height
let contentYoffset = scrollView.contentOffset.y
let distanceFromBottom = scrollView.contentSize.height - contentYoffset
if distanceFromBottom < height {
print(" you reached end of the table")
self.fetchOffset += 10
// changing fillteredPosts. updating tableView.
}
}
}
Here the statements inside scrollViewDidScroll will be executed only when searchBar is empty that means we are not performing a search action
