UISearchControllerがテーブルビューを表示していません

Question

検索テーブルが空ですが、新しいアレイがupdateSearchResultsForSearchControllerに変更されています。私はかなり新しいiOSになっていて、ユーザーの友達から検索するためのテーブルを作ろうとしていました。私はこれについて正しく行きますか？私は一日中検索し、他の投稿はinitWithSearchResultsController:nilを持っていますが、これはうまくいきません。

#import "PFSearchTableViewController.h" 
#import "PFSearchViewCell.h" 

@interface PFSearchTableViewController(){ 
@property (strong, nonatomic) UISearchController * searchController; 
@property (strong, nonatomic) UITableViewController * resultsController; 
} 
@end 

@implementation PFSearchTableViewController 

- (void)viewDidLoad { 
    [super viewDidLoad]; 

    self.resultsController = [UITableViewController alloc]; 
    self.resultsController.tableView.dataSource = self; 
    self.resultsController.tableView.delegate = self; 
    self.searchController = [[UISearchController alloc] initWithSearchResultsController:self.resultsController]; 
    self.tableView.tableHeaderView = self.searchController.searchBar; 
    self.searchController.searchResultsUpdater = self; 

} 

-(void)updateSearchResultsForSearchController:(UISearchController *)searchController{ 

    NSString * dictionaryKey = @"firstName"; 
    NSPredicate * predicate = [NSPredicate predicateWithFormat:@"user.%K CONTAINS[cd] %@", dictionaryKey, searchController.searchBar.text]; 
    self.filetedFriendsList = [self.friendsList filteredArrayUsingPredicate:predicate]; 
    if (self.filetedFriendsList.count > 0) { 


    NSLog(@"^^^ %@", self.filetedFriendsList);} 
    [self.resultsController.tableView reloadData]; 

}

あなたは現在のビューの階層構造を理解するためにsearchcontrollerまたはresultscontrollerを追加しましたか？
