How to Change Strings of "Cancel" Button, "No Results" Label in Uisearchbar of Uisearchdisplaycontroller

How can I change strings of Cancel button, No Results label in UISearchBar of UISearchDisplayController?

I solved it myself.

Cancel Button>

(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
    [controller.searchBar setShowsCancelButton:YES animated:NO];
    for (UIView *subview in [controller.searchBar subviews]) {
        if ([subview isKindOfClass:[UIButton class]]) {
            [(UIButton *)subview setTitle:@"_____" forState:UIControlStateNormal];
        }
    }
}

No Results Text>

- (void)searchDisplayController:(UISearchDisplayController *)controller didLoadSearchResultsTableView:(UITableView *)tableView {
    if (!isChangedNoResults) {
        if ([contactManager.filteredPeople count] == 0) {
            [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(changeNoResultsTextToKorean:) userInfo:nil repeats:YES];
        }
    }
}

I use timer and bool value.
If no timer, can not change text when "No Results" show first.

- (void)changeNoResultsTextToKorean:(NSTimer *)timer {
    if (isChangedNoResults) {
        [timer invalidate];
    }
    else {
        for (UIView *subview in [self.searchDisplayController.searchResultsTableView subviews]) {
            if ([subview isKindOfClass:[UILabel class]]) {
                UILabel *targetLabel = (UILabel *)subview;
                if ([targetLabel.text isEqualToString:@"No Results"]) {
                    NSLog(@"Changed!");
                    [targetLabel setText:@"_____"];
                    isChangedNoResults = YES;
                    [timer invalidate];
                }
            }
        }
    }
}

UISearchDisplayController No Results text

You question may be a duplicate of How can I change strings of "Cancel" button, "No Results" label in UISearchBar of UISearchDisplayController?

Here's a modification of the answer given there:

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller 
        shouldReloadTableForSearchString:(NSString *)searchString {
    dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 0.001);
    dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
        for (UIView* v in self.sbc.searchResultsTableView.subviews) {
            if ([v isKindOfClass: [UILabel class]] && 
                    [[(UILabel*)v text] isEqualToString:@"No Results"]) {
                // .. do whatever you like to the UILabel here ..
                break;
            }
        }
    });
    return YES;
}

Basically what you're asking to do is simply to access the UILabel that is displaying the "No Results" text. There is no official way to do that. The workaround, as suggested on that page, is to look for the UILabel (by enumerating all the subviews of the search results table) and modify it. I generally can't encourage this sort of thing, but I find Apple's refusal to supply an official way to grapple with this "No Results" label to be downright obnoxious, so no holds are barred in this particular fight.

How do I cover the no results text in UISearchDisplayController's searchResultTableView?

The easiest way to work around this is to return 1 in numberOfRowsInSection while the query is in progress and leave the dummy cell empty or set its hidden property to YES so it is not visible.

Create a custom view with a label having text "No Results" and load it whenever your search query contain no value.

I guess, it would be enough to set sections number to 0 during search.
