iPhone:Safari与从“主屏幕"启动书签 [英] iPhone: Safari vs. launch from "Home Screen" bookmark

问题描述

两者之间有什么区别?他们是否都启动Safari(主屏幕不显示URL/工具栏?

What's the difference between these two? Do they both launch Safari (with the exception that the home-screen doesn't show a URL/tool bar?

我发现主屏幕版本中出现了怪异的怪癖.它们有不同的渲染引擎吗?例如，mailto:在主屏幕模式下不起作用，并且如果我从移动Safari浏览器访问Web应用程序，则不会出现一些小的渲染/css样式错误.

I've found weird quirks that appear in home screen version..do they have different rendering engines? For example, mailto: doesn't work in home-screen mode, and there are some small rendering/css-styling bugs that don't appear if I visit my web application from mobile Safari.

谢谢！

推荐答案

当作为浏览器或主屏幕应用程序启动时，Apple正在为Sarari浏览器使用两种不同的运行时环境. 主屏幕环境受到多种限制:

Apple is using two different Runtime Environments for the Sarari Browser when launched as a browser or as a Homescreen app. The Homescreen environment suffers from multiple limitations:

1. 缺乏打印，mailto，缓存支持，并且列表还在继续...
2. 在iOS 4.3中，它没有启用新的Nitro引擎，因此在这种环境下性能始终会较低
