Question

こんにちは、私は 4 つのボタンを使用しようとしていますが、それぞれのボタンを押すと異なるアラートが表示されます。問題が発生しています。3 つのボタンがあり、「Rate My App」ボタンを追加することにしましたが、機能しません。助けてください。(ちなみにエラーはExexted Expression です)(Org.=Organization (アプリ内固定), Email- アプリ内リアルメール,

    }
}

最後に (TAG_RATE) を追加する前は機能していましたが、なぜ機能しなくなったのかわかりません。助けてください。

Answer 1

コードにタイプミスがあります:;最後の 2 つのelse if条件の後に余分があります:

    else if (alertView.tag == TAG_EDEV)/*;*/{  // extra `;`
            //...
    }
    else if (alertView.tag == TAG_RATE)/*;*/{   // extra `;`       //Expected Expression
            // ...
    }
