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
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">
