如何将 UISearchBar 添加到同一 UIViewController 中的两个 TableView

Question

1. 我正在使用 JASidePanel - https://github.com/gotosleep/JASidePanels 来创建菜单效果。
2. 我正在使用 xib。
3. 我的类扩展了 UIViewController。
4. searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText: 时不知道如何显示到另一个 tableView
5. 您会看到第一个 tableView 是 Panel，过滤后的 tableView 是带有名称的 Thumb。
6. 以下代码在需要添加第二个 tableview 时停止。

SidePanelViewController.h

@interface SidePanelViewController : UIViewController <UISearchBarDelegate, UISearchDisplayDelegate, UITableViewDataSource, UITableViewDelegate, MFMailComposeViewControllerDelegate, MFMessageComposeViewControllerDelegate>
{
    IBOutlet UIImageView *_photoProfile;
    IBOutlet UILabel *_nameLabel;
    NSArray *_menuArray;
}

@property (nonatomic, readonly) IBOutlet UISearchBar *searchBar;
@property (nonatomic, strong) IBOutlet UITableView *tableView;
@property(nonatomic, strong) NSMutableArray *tableViewData;
@property(nonatomic, strong) NSMutableArray *originalTableViewData;
@property(nonatomic, strong) NSMutableArray *searchArray;
@property(nonatomic, strong) NSMutableDictionary *units;

SidePanelViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];


    // Do any additional setup after loading the view from its nib.
    _menuArray = [[NSArray alloc]initWithObjects:@"Home",@"Meu QR Sem Hora", @"Favoritas", @"Minha Pontuação", @"Minha Conta",@"Convidar Amigos", @"Ajuda", @"Fale Conosco",@"Privacidade e Termos", nil];

    _tableViewData = [[NSMutableArray alloc] initWithArray:_menuArray];
    // Don't show the scope bar or cancel button until editing begins
    [_searchBar setShowsScopeBar:NO];
    [_searchBar sizeToFit];

    //
    // Create a header view. Wrap it in a container to allow us to position
    // it better.
    //
    UIView *containerView =
    [[UIView alloc]
     initWithFrame:CGRectMake(0, 0, 320, 30)];
    UILabel *headerLabel =
    [[UILabel alloc]
     initWithFrame:CGRectMake(0, 0, 320, 30)];
    headerLabel.text = NSLocalizedString(@"Perfil", @"");
    headerLabel.textColor = [UIColor blackColor];
    headerLabel.shadowColor = [UIColor whiteColor];
    headerLabel.shadowOffset = CGSizeMake(0, 1);
    headerLabel.font = [UIFont boldSystemFontOfSize:22];
    headerLabel.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5];
    [containerView addSubview:headerLabel];
    self.tableView.tableHeaderView = containerView;

    //SetName and Picture
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    _nameLabel.text = [defaults valueForKey:@"name"];
    _photoProfile.image = [UIImage imageWithData:[defaults objectForKey:@"Photo"]];

Answer 1

不知道你是否解决了这个问题，但你是什么意思显示到另一个表视图？如果您的意思是它显示的与您发布的第二张图片相似，那么我会继续说，如果您使用“搜索栏和搜索显示”，搜索栏应该已经有一个？

self.searchDisplayController.searchResultsTableView

如果您确实使用了该搜索栏和显示，您可以使用 NSPredicate 并创建一个过滤器可变数组，该数组复制并根据您的 originalTableViewData 进行谓词。 希望这对您或其他仍然感兴趣的人有所帮助。
