Hide the dropdown when no items are found

[Ferdinando]

Hi,

Is it possible to hide the suggestions view when no items are found?

Hi Ferdinando,

Yes, you can hide the suggestion list when there are no matching items.

In order to do this you should conform to the TKAutoCompleteDelegate protocol and implement the autocomplete:willShowSuggestionList: method. This method provides you with the array of matches according to the input. You should check if there are any matches and in case there are no matches you should hide the suggestions list. Consider the following code snippet.

-(void)autoComplete:(TKAutoCompleteTextView *)autocomplete willShowSuggestionList:(NSArray<__kindof TKAutoCompleteToken *> *)suggestionList
{
    if (suggestionList.count == 0) {
        autocomplete.suggestionView.hidden = YES;
    }
}

With 2015.3.1105 framework version I get always a suggestionList.count = 0 in this delegate function, even when there are matching items.

¿Any work around?

I found it myself.

-(void)autoComplete:(TKAutoCompleteTextView *)autocomplete willShowSuggestionList:(NSArray<__kindof TKAutoCompleteToken *> *)suggestionList
{
    NSInteger items = ((TKSuggestionListView*)autocomplete.suggestionView).items.count;
    if (items == 0) {
        autocomplete.suggestionView.hidden = YES;
    } else {
        autocomplete.suggestionView.hidden = NO;
    }
}
