Instance Method

searchDisplayController(_:shouldReloadTableForSearch:)

Asks the delegate if the table view should be reloaded for a given search string.

Declaration

optional func searchDisplayController(_ controller: UISearchDisplayController, shouldReloadTableForSearch searchString: String?) -> Bool

Parameters

controller

The search display controller for which the receiver is the delegate.

searchString

The string in the search bar.

Return Value

true if the display controller should reload the data in its table view, otherwise false.

Discussion

If you don’t implement this method, then the results table is reloaded as soon as the search string changes.

You might implement this method if you want to perform an asynchronous search. You would initiate the search in this method, then return false. You would reload the table when you have results.
