在 Ruby 中检测 iPad 3 [英] Detect iPad 3 in Ruby

问题描述

是否可以使用 ruby​​/rails 检测 iPad 3(又名新 iPad)?如果是这样，我将如何去做?

Is it possible to detect an iPad 3 (aka The new iPad) using ruby/rails? If so, how would I go about doing it?

推荐答案

您可以检测设备，但我认为无法检测设备版本.据我所知，Apple 提供了一个用户代理字符串，如下所示:

You can detect the device but I do not think it is possible to detect device version. As far as I know, Apple provides a user agent string which appears as follows:

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 
(KHTML, like   Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

此字符串中没有机器版本信息，我不知道其他检测用户机器的方法.

There is no machine version information in this string and I do not know any other way to detect user machine.

如果您不知道如何在 Rails 中获取用户代理字符串，请查看此处.
