ios - 変更に反応しないラベル

Question

問題があります。いくつかのビューコントローラーがあります。一方はPSACurrentGame、もう一方はと呼ばれPSAEnterScoresます。PSACurrentGameの親クラスですPSAEnterScores。PSACurrentGameからラベルを変更しようとしていPSAEnterScoresます。しかし、私はすでに親クラスのことでそれを理解しています。本当の問題は、正しいプロパティが変数にリンクされているにもかかわらず、変数のテキストが変更されないことです。メソッドの変更にはlanbelが反応することを確認しましたviewDidLoadが、子クラスでの変更には反応しません。誰かが理由を知っていますか？

以下のコード:

PSACurrentGame.h:

さらに何か必要な場合は、コメントしてください。追加します。

編集: 上部のテキストを変更しましたが、ここにも記載します。ラベルは、独自のクラスの変更に応答するようになりましたが、子クラスに応答するようになりました。子クラスには、親クラスの変数にアクセスするための読み取り専用権限しかありませんか?

この例をアプリケーションで使用して、View Controller 間でデータを転送しました。だから、それは役立つかもしれません:

改善できる点は次の 2 つだと思います。

1) インターフェイスコントロールごとに 1 つ作成する代わりに、IBOutletCollection を使用します。

2) 共有データソースを使用し、その値が変更されたときに通知を受け取ります。次に、次のように、独自の ViewController 内でコントロールを変更できます。

self.dataStore addObserver:self forKeyPath:@"gameScore" options:0 context:nil];

//...

- (void)observeValueForKeyPath:(NSString *)keyPath
                  ofObject:(id)object
                    change:(NSDictionary *)change
                   context:(void *)context {

    if ([keyPath isEqual:@"gameScore"]) {
        //update your IBOutletCollections...
    }
}
