Case insensitive SearchBar Xcode

Question

I'm developing an app in Xcode in Objective-C. The app has a TableView with restaurants. My problem is that when I use the SearchBar the filter is case sensitive and I want to get a case insensitive search. I know I have to change my searchBar textDidChange method, and I looking for help but I don't know how to change it in my case. Can someone help me? Thank you very much.

This is my searchBar textDidChange method:

-(void) searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText {

    if (searchText.length == 0) {
        //Set our boolean flag
        isFiltered = NO;
    } else {
        //Set our boolean flag
        isFiltered = YES;
    }
    //Alloc and init our filteredData
    filteredRest = [[NSMutableArray alloc] init];

    for (Restaurant *item in originData) {
        if ([item.title containsString:searchText]) {
            [filteredRest addObject:item];
        }
    }

    //Reload our table view
    [self.tableView reloadData];
}

Thank you.

Change this line

if ([item.title containsString:searchText]) {
    [filteredRest addObject:item];
}

With this

if ([[item.title lowercaseString]containsString:[searchText lowercaseString]]) {
    [filteredRest addObject:item];
}
