我一直试图让我的网络应用程序出现在iOS设备上。当我将应用程序添加到我的主屏幕后加载应用程序时，我得到一个白色屏幕，没有任何加载。但是，如果我将元标记移动到我的图标和启动屏幕下方，应用程序将加载正常，但启动屏幕将无法加载。无论代码在何处，图标都适用于所有设备。
以下是我目前的代码：

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

包含谷歌驱动器链接的长href的原因是因为我有谷歌潜水网站用于测试目的。它基本上代表了网站地址。
＆LT; - 编辑 - ＆GT;
这是代码现在的样子我已经重命名了一些文件并移动了它们。我注意到不需要谷歌驱动器地址。

图标在我试用该应用的任何设备上都能正常工作。但是启动画面仍然无效。
只有一页说HELLO WORLD！当它被添加到主屏幕时，图标可以工作，但启动画面不会。

根据Marconi's answer上的Mulitple “apple-touch-startup-image” resolutions for iOS web app (esp. for iPad)?，请尝试使用这些代码作为启动画面元标记:(您还需要iPhone 6＆amp; 6 Plus标签）
