Question

我在一个视图控制器和一个搜索栏中有两个表。第一个视图控制器和搜索栏的功能还可以，直到我添加了第二个表。现在，当我想搜索某些东西时，研究就在第一个表格中，我不想要这个。

这是我的代码：

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
    [self.searchResult removeAllObjects];
    NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@", searchText];

    self.searchResult = [NSMutableArray arrayWithArray: [self.tableData filteredArrayUsingPredicate:resultPredicate]];

}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self filterContentForSearchText:searchString scope:[[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]];

    return YES;
}



- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (tableView.tag==1) {
    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        return [self.searchResult count];
    }
    else
    {return [self.tableData count];}

    }
    else return historique.count;
}


- (NSString *)tableView:(UITableView *)aTableView titleForHeaderInSection:(NSInteger)section {
    return [[content objectAtIndex:section] objectForKey:@"headerTitle"];
}

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
    return [content valueForKey:@"headerTitle"];
}

- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index {
    return [indices indexOfObject:title];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    if (tableView.tag==1) {
        return  [content count];
    }else
    return 1;
}


UITableViewCell *cell ;

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

    if (tableView.tag==0) {

 cell = [tableView dequeueReusableCellWithIdentifier:@"cell2"];

        if (cell == nil)
        {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        }
        if (tableView == self.searchDisplayController.searchResultsTableView)
        {
            cell.textLabel.text = [self.searchResult objectAtIndex:indexPath.row];

        }
        else

        cell.textLabel.text = [historique objectAtIndex:indexPath.row];

    }


    if (tableView.tag==1) {
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

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

    if (tableView == self.searchDisplayController.searchResultsTableView)
    {
        cell.textLabel.text = [self.searchResult objectAtIndex:indexPath.row];

    }
    else
    {
        cell.textLabel.text = self.tableData[indexPath.row];
    }}
    return cell;

}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    DefinitionViewController *secondViewController = [[UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]]instantiateViewControllerWithIdentifier:@"definition"];

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    NSString *str = cell.textLabel.text;
    NSString *uu;

    if ([[transaction valueForKey:str] isKindOfClass:[NSArray class]]) {

        NSLog(@"yes");
        NSArray *jsonArray = (NSArray *)[transaction valueForKey:str];
        uu = [jsonArray componentsJoinedByString:@"\n"];
        secondViewController.definitionsArray=jsonArray;


    }

    else{
        uu=[transaction valueForKey:str];

    }

    NSMutableArray *values = [[NSMutableArray alloc] initWithArray:[[NSUserDefaults standardUserDefaults] arrayForKey:@"histroriqueValues"]];
    [values addObject:uu];
    [[NSUserDefaults standardUserDefaults] setObject:values forKey:@"histroriqueValues"];
    historiqueValue = [[[NSUserDefaults standardUserDefaults] arrayForKey:@"histroriqueValues"]mutableCopy];
    [[NSUserDefaults standardUserDefaults] synchronize];

}

tableView.tag = 0是我想要进行搜索的表。我放了断点，当我点击搜索栏时，搜索的表是tableView.tag = 1.

我用UITableViewController做了一个小例子项目。如果你需要，我可以把它推到一个github仓库，这样你就可以抓住它并在它上面构建。

    NSArray *filteredContent;

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    content = @[@"CECI",@"CELA",@"CELUI-CI",@"ET CA",@"ETC"];
    self.tableView.dataSource = self;
    self.searchDisplayController.delegate = self;
    self.searchDisplayController.searchResultsDataSource = self;

    self.searchDisplayController.searchBar.delegate = self;

}


- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{

     NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@", searchString];
    filteredContent = [NSArray arrayWithArray:[content filteredArrayUsingPredicate:predicate]];
    return YES;
}
-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption {
    return YES;
}




-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (tableView  == self.tableView) {
        return content.count;
    } else {
        return filteredContent.count;
    }
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"test"];
    if (tableView == self.tableView) {
        cell.textLabel.text =  content[indexPath.row];
    } else {

    }
    return cell;
}


@end

我应该搜索单词时选择表格视图
