Question

请原谅我对这个问题的无知，但我仍然试图掌握基本知识，并且现在已经把头撞到墙上几天了。

我基本上有一个NSArray我用来填充我希望用户能够搜索的UITableView - 并且过滤包含搜索条件中字符的结果，作为用户类型。

有很多教程用于连接UITableViews和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，当用户点击按钮时，其内容显示在UIView中，我似乎已将UISearchBar添加到同一视图的顶部，并且我想'我添加了UISearchDisplayController。但是，我似乎无法让所有三个人都能很好地发挥。

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;
}

我还在我的实现文件的顶部有一些东西来存储各种各样的位

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

NSDictionary * fullListOfRecipesForTableView;
NSMutableDictionary * fullListForSearchResultsInTableView;

UITableView * tableView;
}

此代码会在您的tableview

中添加搜索栏

  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];

添加搜索栏后，检查如何传递数据并设置委托和数据源，我建议你仔细阅读Tutorial。
