用户缩放后重置 iPhone Safari 的视口

有谁知道如何让 iPhone Safari 视口重置为我选择的比例（如果用户使用捏合进行缩放）？看来，虽然我可以使用 jQuery 来更改比例，只要我喜欢：

$('meta[name=viewport]').attr('content', 'width=640, maximum-scale=0.5');

一旦用户缩放，就没有办法更改比例？

理想情况下，我需要让用户扩展，因此关闭用户扩展是最后的手段。看起来这是不可能的。我考虑过使用 jQuery 重新加载页面，但这并不理想，但现在会进行测试并报告。

谢谢，汤姆

Does anyone know how I can get the iPhone Safari viewport to reset to a scale of my choice are a user has scaled using pinch?
It seems that although I can use jQuery to change the scale when ever I like by:

$('meta[name=viewport]').attr('content', 'width=640, maximum-scale=0.5');

As soon as the user has scaled, there is no way of changing the scale?

I ideally need to let the user scale, so turning off user scaling is a last resort.
It looks like it's not possible.
I've considered using jQuery to reload the page, but this isn't ideal but will test now and report back.

Thanks,
Tom
