如果我有一个纯粹用 HTML 和 JS 编写的应用程序，我应该将它封装在 UIWebView 中还是应该在 Mobile Safari 中打开它

推荐答案

UIWebView 是否使用与 Mobile Safari 相同的 JavaScript 引擎?

Does UIWebView use the same JavaScript engine as Mobile Safari?

UIWebView 没有 Nitro Javascript 引擎，因此它执行 JS 的速度比 Mobile Safari 慢.所以不一样.

UIWebView does not have the Nitro Javascript engine, so it executes JS slower than Mobile Safari. So it's not the same.

另外，UIWebView 是否像 Mobile Safari 一样支持所有 HTML5 功能?我特别关心 Web SQL 和 Web Workers

不确定这个.可能不是.至少 UIWebView 在某些功能上比 Safari 更严格一些.示例:通过JS设置宽高样式时，需要在数字后面加上'px'，而Mobile Safari不需要.

Not sure about this one. Probably not. At least UIWebView is a bit more strict than Safari on certain features. Example: when setting a width/height style through JS, you need to add 'px' behind the number, while Mobile Safari does not require that.

如果您想在 App Store 上发布应用程序，您必须将其打包.如果没有，您实际上不必这样做.

If you want to release the app on the App Store, you will have to wrap it. If not, you don't really have to.

Apple Store 是否接受纯 HTML 和 JS 应用程序?

Are pure HTML and JS apps accepted on the Apple store?

如果你包装它，是的.但正如 James Webster 所写，它有一些局限性.

If you wrap it, yes. But it has some limitations, as James Webster wrote.
