您可以發佈用於在應用程序中包含圖標的代碼嗎？ – 2015-02-08 23:49:56

我以爲我只是把文件放在那個目錄下。對不起，這是我第一次使用Rails。我如何包含圖標？ – 2015-02-09 00:00:10

嘗試把圖像在app/assets/images目錄中並重新啓動服務器。

更新

這裏是你如何可以包括一個蘋果觸摸圖標...

應用/佈局/ application.html.erb

<head> 
    <%= favicon_link_tag "apple-touch-icon-100.png", 
         rel: "apple-touch-icon", 
         sizes: "100x100", 
         type: "image/png" %> 
</head>

確保apple-touch-icon-100.png中存在app/assets/images目錄。

我剛剛嘗試過，但沒有奏效。我正在使用2張100x100的圖像 – 2015-02-08 23:35:50

您的app/assets/images'文件夾中是否有名爲'apple-touch-icon.png'的圖像？ – 2015-02-08 23:39:37

是的，我把它放在那裏，因爲你建議 – 2015-02-08 23:44:27
