私は iOS 開発が初めてで、辞書を作成しようとしています。私の最初の画面では、上部に検索バーがあり、TableViewその下にすべてのエントリがあります。検索バーに入力すると、一致するエントリで TableView がフィルタリングされます。リストすべてモードまたはフィルター モードでいずれかのセルをクリックすると、別のビューがプッシュされ、単語の名前と定義が表示されます。
表のセルをクリックするたびに新しい画面を開くことができますが、何らかの理由で、新しい画面の 2 つのラベル (単語と定義) が選択内容で更新されず、空のままになります。 . IBOutletただし、これら 2 つの を XIB ファイルに正しく設定したと思います。なぜなら、 のtext属性をログに記録するとUILabel、それらが正しく出力されるからです。ヘルプ？
EntryViewController.h (2 番目の画面):

@property (nonatomic, strong) IBOutlet UILabel *definition;

@implementation EntryViewController
@synthesize word, definition;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
self.word = [[UILabel alloc] init];
self.definition = [[UILabel alloc] init];
return self;
}
- (void)viewDidLoad {
[super viewDidLoad];
[self.navigationController setNavigationBarHidden:NO];
// Do any additional setup after loading the view.

編集: AppDelegate のヘッダーと実装ファイルを含めています。エラーは、現在何にも接続していないのどこかにあると感じていますがnavigationController、XIB にエラーがないため、どこに接続すればよいかさえわかりません。
