このコードはまさにあなたが望むことをします。これは、Saxon Druce が推奨するリンクの #9 にインスパイアされていますが、別の方法でより完全に行われています。カスタム infoWindow に追加されたボタンのタップを検出します。2 つの偽のボタンを使用してカスタムの infoWindow を作成し (いずれにしてもアクションをトリガーしないため、実際には画像に置き換えることができます)、infoWindow の上に 2 つの本物の透明なボタンを使用して透明な UIView を追加します。これらのボタンは、アクションをトリガーします。
最後に、infoWindow 自体が移動するときにオーバーレイされた UIView を移動するために、いくつかのデリゲート メソッドまたは KVC を使用します。
