推荐答案

我认为你应该可以使用safari元标记操作视口

i think you should be able to manipulate the viewport using the safari meta tags

https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariHTMLRef/Articles/MetaTags.html#//apple_ref/doc/uid/TP40008193-SW6

例如，要将视口宽度设置为设备的宽度，请将其添加到HTML文件中：

For example, to set the viewport width to the width of the device, add this to your HTML file:

<meta name = "viewport" content = "width = device-width">

要将初始比例设置为1.0，请将其添加到HTML文件中：

To set the initial scale to 1.0, add this to your HTML file:

<meta name = "viewport" content = "initial-scale = 1.0">

要设置初始比例并关闭用户缩放，请将其添加到HTML文件中：

To set the initial scale and to turn off user scaling, add this to your HTML file:

<meta name = "viewport" content = "initial-scale = 2.3, user-scalable = no">
