Question

Java クラスを Objective C (cradle プラグインを使用した J2Objc) に変換しています。シンプルな Android アプリと単体テストは問題なく動作します。同じ単純な Objective C iOS アプリも完全に機能します。ただし、Swift プロジェクトで同様のコードを記述しようとすると、インスタンス変数にアクセスしたり、メソッドを検索したりできません。これは私にとって比較的新しいことなので、基本的なものが欠けている可能性があります。

Objective C のコードは次のとおりです。完全に動作します。

SHRRefreshAppointments *mTest = [[SHRRefreshAppointments alloc] initWithId:nil withBoolean:true];
[mTest run];
SHREventListResp *mResp = [SHREventListResp parseFromWithByteArray:mTest->mResponseData_];
NSLog(@"%@", mResp.description);

Swift の同じコード - Objective C ですぐに利用できるインスタンス変数 mResponseData が見つかりません:

let mTest : SHRRefreshAppointments = SHRRefreshAppointments(id: nil, withBoolean: true)
mTest.run()
var mResp : SHREventListResp = SHREventListResp.parseFromWithByteArray(mTest.)

どんな助けでも大歓迎です。

私の限られた理解は、Swift が Objective C のプロパティをフィールド自体ではなく、フィールドとしてインポートするということです。したがって、mResponseData のアクセサーメソッドが必要になります。

幸いなことに、j2objc にはProperty アノテーションがあり、これを mResponseDate フィールドに追加できるため、同等の Objective C プロパティが変換中に生成されます。そのプロパティは、後で Swift にインポートする必要があります。

Property アノテーションは、(Objective C で @synthesize が行うように) デフォルトのアクセサーも生成するため、Java クラスに既にアクセサーがある場合は、getter= および setter= @property 属性を使用してそれらを指定します。トランスレータのtestProperties() テストは、複雑なプロパティアノテーションの例を示しています。
