An elegant search controller which replaces the UISearchController for iOS

    // 1. Create hotSearches array
    NSArray *hotSeaches = @[@"Java", @"Python", @"Objective-C", @"Swift", @"C", @"C++", @"PHP", @"C#", @"Perl", @"Go", @"JavaScript", @"R", @"Ruby", @"MATLAB"];
    // 2. Create searchViewController
    PYSearchViewController *searchViewController = [PYSearchViewController searchViewControllerWithHotSearches:hotSeaches searchBarPlaceholder:@"Search programming language" didSearchBlock:^(PYSearchViewController *searchViewController, UISearchBar *searchBar, NSString *searchText) {
        // Call this Block when completion search automatically
        // Such as: Push to a view controller
        [searchViewController.navigationController pushViewController:[[UIViewController alloc] init] animated:YES];
        
    }];
    // 3. present the searchViewController
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:searchViewController];
    [self presentViewController:nav  animated:NO completion:nil];

// 1. Set dataSource
searchViewController.dataSource = self;
// 2. Implement dataSource method

// 1. Set searchResultShowMode
searchViewController.searchResultShowMode = PYSearchResultShowModeEmbed;
// 2. Set searchResultController 
searchViewController.searchResultController = [[UIViewController alloc] init];

// Set hotSearchStyle
searchViewController.hotSearchStyle = PYHotSearchStyleColorfulTag;

// Set searchHistoryStyle
searchViewController.searchHistoryStyle = PYSearchHistoryStyleBorderTag;

// Set searchHistoriesCachePath
searchViewController.searchHistoriesCachePath = @"The cache path";

// Set searchHistoriesCount
searchViewController. searchHistoriesCount = 6;

// Set searchResultShowMode
searchViewController.searchResultShowMode = PYSearchResultShowModeEmbed;

// Set searchSuggestionHidden
searchViewController.searchSuggestionHidden = YES;
