请原谅我对这个问题的无知，但我仍在努力掌握基础知识，并且已经为此苦苦挣扎了几天。

我基本上有一个NSArray我用来填充一个UITableView我希望用户能够搜索的 - 并在用户键入时过滤包含搜索条件中的字符的结果。

那里有很多关于连接的教程UITableViews，UISearchDisplayControllers但它们都使用 xib 文件，我想以编程方式添加所有内容。

我有UITableView, 当用户点击一个按钮时，它的内容显示在 aUIView中，我似乎UISearchBar在同一个视图的顶部添加了 ，我认为我已经添加了UISearchDisplayController. 但是，我似乎无法让这三个人都玩得很好。

这是我到目前为止所拥有的

- (IBAction)createSearchList:(id)sender {

//Make the list
AAPjsonParse * makeTheFullList = [[AAPjsonParse alloc] init];    
fullListOfRecipesForTableView = [makeTheFullList generateFullListOfRecipes];
fullListForSearchResultsInTableView = fullListOfRecipesForTableView;
recipeListForTable = [fullListForSearchResultsInTableView allKeys];
recipeListForTable = [recipeListForTable sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];


//Create the UITableView
tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 44, 300, 724) style:UITableViewStylePlain];
tableView.dataSource = self;
tableView.delegate = self;

//Add the TableView to the view
[self.searchView addSubview:tableView];

//Create a UISearchBar for the TableView

UISearchBar * searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 300, 44)];
//Set the searchBar as the delegate
searchBar.delegate = self;
//Add the searchBar to the UITableView
[self.searchView addSubview:searchBar];

//Create the searchViewController
UISearchDisplayController * searchController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
//Set the dataSource for the search as self
searchController.searchResultsDataSource = self;
//Set the results delegate as self – this is the view that's overlaid onto the full listing view (I think?)
searchController.delegate = self;

}

-(NSInteger) numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}

-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [recipeListForTable count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString * CellIdentifier = @"RecipeCell";

UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}

NSString * cellTitle = [recipeListForTable objectAtIndex:indexPath.row];

cell.textLabel.text = cellTitle;

return cell;
}

我的实现文件顶部还有一些东西来存储各种位

{    
NSArray * recipeListForTable;
NSMutableArray * recipeListForSearch;
int selectedRecipeIndex;

NSDictionary * fullListOfRecipesForTableView;
NSMutableDictionary * fullListForSearchResultsInTableView;

UITableView * tableView;
}

This code will add a searchbar to your tableview

  searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(self.tblView.frame), 44)];
        searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
        searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
       // searchBar.tintColor = [UIColor lightGrayColor];



    searchBar.placeholder = @"What are you eating today...";
    searchBar.delegate = self;
    searchBar.searchBarStyle = UISearchBarStyleMinimal;

    searchDisplayController.delegate = self;
    searchDisplayController.searchResultsDataSource = self;

       [self.tblView setTableHeaderView:searchBar];

After adding searchbar check how to pass data and set delegate and datasource, I would suggest you to go through this Tutorial.
