objective-c - オーシャンカラー（または他の色）を設定する

Question

[UIColor colorWithRed：0.000 green：0.333 blue：0.557 alpha：1.000]

海の色を与える必要があります。

オブジェクト（私の場合はボタン）プロパティから海の色を直接選択すると、まったく同じ色ではないことがわかります。特定の色の値を正確に検出するツールがあるかどうか知っていますか？

Answer 2

カラーピッカーはあなたを助けますか？Macではhttp://colorsnapper.com/を使用し、Webページの場合はhttps://chrome.google.com/webstore/detail/penduleを使用します。

目的の色にカーソルを合わせると、16進コードを取得できます。16進文字列からUIColorを作成するにはどうすればよいですか？を参照してください。16進数からUIColorへの変換の詳細については、またはこの便利なWebアプリを使用してください。

（注：ColorSnapperは無料ではありませんが、iOS UIColorオプションがあり、16進数から自分で変換する必要がありません）

Answer 3

以下は、上記のTimmKentの回答を少し変更したものです。このバージョンでは、クラス定数を使用して、色を参照するときに括弧を入力しないようにしています。

定数を使用すると、これを入力する代わりに：

let myColor = UIColor.cantaloupe()

次のように入力できます。

let myColor = UIColor.cantaloupe

更新された拡張機能は次のようになります。
