问题
During the search I want to disable the pull to refresh mechanism. So I disabled the refresh control and removed it. But when pull down to refresh the beginRefresh method is called and the cells keep being down for 2 seconds like there is a refresh.
func searchBarShouldBeginEditing(searchBar: UISearchBar) -> Bool {
resultSearchController.searchBar.selectedScopeButtonIndex = 0
refreshControl!.enabled = false
refreshControl?.removeFromSuperview()
return true
}
回答1:
When search then check if refreshControl has superView and Remove from superView After search End Add it again, the condition will look like :
if self.refreshControl.isDescendant(of: self.tblView) {
self.refreshControl.removeFromSuperview()
}

Use these two functions if you want to create or delete refresh controls in the top of UITableView.
func createRefreshControl() {
// Create RefreshControl and add to tableView
self.refreshControl = UIRefreshControl()
self.refreshControl!.attributedTitle = NSAttributedString(string: " ↓ Refresh ↓ ")
self.refreshControl!.addTarget(self, action: "refresh:", forControlEvents: UIControlEvents.ValueChanged)
}
func deleteRefreshControl() {
// delete RefreshControl
self.refreshControl = nil
}

Try with this code, it worked for me:
var refresh : UIRefreshControl!
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
print("START TABBAR")
if #available(iOS 10.0, *) {
if let refresh = self.tableView.refreshControl {
if refresh.isDescendant(of: self.tableView) {
self.tableView.refreshControl?.removeFromSuperview()
}
}
} else {
for subview in self.tableView.subviews {
if let refresh = subview as? UIRefreshControl {
refresh.removeFromSuperview()
}
}
}
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
print("FINISH SEARCH")
self.refresh = UIRefreshControl()
self.refresh.attributedTitle = NSAttributedString(string: "Update data")
self.refresh.addTarget(self, action: #selector(updateFunction), for: .valueChanged)
if #available(iOS 10.0, *) {
self.tableView.refreshControl = self.refresh
} else {
self.tableView.addSubview(self.refresh)
}
}
@objc func updateFunction() {
//Your function to update the tableView
}
You will need to implement the UISearchBarDelegate
in order to call those functions.
It also works for iOS 9
