自定义URL会打开其他本机应用程序.如果要打开Web应用程序，则只需传递http://URL，但是这样做会加载标准Safari浏览器，而不是在主屏幕中点击Web Clip时会获得的新Webkit实例.

Custom URLs open other native apps. If you want to open a web app, you can simply pass the http:// URL, however, doing so will load the standard Safari browser rather than a new instance of webkit that you would get with tapping the web clip in the home screen.
