描述 (Description)

iOS 7+允许您构建全屏应用，当您的状态栏与您的应用重叠时，这可能会产生问题。 Framework7通过检测您的应用是否处于全屏模式来解决此问题。如果你的应用程序处于全屏模式，那么Framework7会自动将with-statusbar-overlay类添加到《html》 （如果app不是全屏模式，则删除），你需要在《body》添加statusbar-overlay类如下面的代码所示 -

<html class = "with-statusbar-overlay">
...
   <body>
      <div class = "statusbar-overlay"></div>
      ...

默认情况下， 《div》将始终隐藏并固定在屏幕顶部。只有当应用程序处于全屏模式并且with-statusbar-overlay类添加到《html》时，它才会显示。

例子 (Example)

以下示例演示了Framework7中状态栏的使用 -

<!DOCTYPE html>
<html>
   <head>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1, 
         maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />
      <meta name = "apple-mobile-web-app-capable" content = "yes" />
      <meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
      <title>My App</title>
      <link rel = "stylesheet" 
         href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
      <link rel = "stylesheet" 
         href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.colors.min.css" />
   </head>
   <body>
      <div class = "statusbar-overlay"></div>
      <div class = "panel-overlay"></div>
      <div class = "panel panel-right panel-reveal">
         <div class = "content-block">
            <p>Contents goes here...</p>
         </div>
      </div>
      <div class = "views">
         <div class = "view view-main">
            <div class = "navbar">
               <div class = "navbar-inner">
                  <div class = "center sliding">My App</div>
                  <div class = "right">
                     <a href = "#" class = "link icon-only open-panel"><i class = "icon icon-bars"></i></a>
                  </div>
               </div>
            </div>
            <div class = "pages navbar-through toolbar-through">
               <div data-page = "index" class = "page">
                  <div class = "page-content">
                     <p>This is simple application...</p>
                     <p>page contents goes here!!!</p>
                  </div>
               </div>
            </div>
            <div class = "toolbar">
               <div class = "toolbar-inner">
                  <a href = "#" class = "link">First Link</a>
                  <a href = "#" class = "link">Second Link</a>
               </div>
            </div>
         </div>
      </div>
      <script type = "text/javascript" 
         src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>
      <script>
         // here initialize the app
         var myApp = new Framework7();
         // If your using custom DOM library, then save it to $$ variable
         var $$ = Dom7;
         // Add the view
         var mainView = myApp.addView('.view-main', {
            // enable the dynamic navbar for this view:
            dynamicNavbar: true
         });
         //use the 'pageInit' event handler for all pages
         $$(document).on('pageInit', function (e) {
            //get page data from event data
            var page = e.detail.page;
         })
      </script>
   </body>
</html>

输出 (Output)

让我们执行以下步骤，看看上面给出的代码是如何工作的 -

将上面给出的html代码保存为服务器根文件夹中的status_bar.html文件。
将此HTML文件打开为http://localhost/status_bar.html，输出显示如下。

该示例显示了statusbar-overlay的使用，它允许您在状态栏与应用程序重叠时构建全屏应用程序。
