Is this a Facebook for iOS WebView User Agent?
提问by Jim Rubenstein
I'm looking through some logs trying to explain some "interesting" behavior and I'm seeing some users come to my application with a user agent similar to this one:
我正在查看一些日志，试图解释一些“有趣”的行为，我看到一些用户带着类似于这个的用户代理来到我的应用程序：
Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
If I run this string through udger.comI get the following result:

This screen shot and user agent confuses me because it says it's the mobile safari for iPod and iPad. I see iPadin the first part of the user-agent, but I also see a lot of references to FB and iPhone and iOS and all kinds of other things.
这个屏幕截图和用户代理让我感到困惑，因为它说它是 iPod 和 iPad 的移动 safari。我iPad在用户代理的第一部分看到了，但我也看到了很多对 FB、iPhone 和 iOS 以及各种其他东西的引用。
I'm curious if this is a "generic" user-agent that is served up by the Facebook for iOS application, and if it is - is the device an iPad or is it just not clear enough to tell?
我很好奇这是否是 Facebook 为 iOS 应用程序提供的“通用”用户代理，如果是 - 该设备是 iPad 还是不够清楚？

The following is the user agent string from an iPhone 4s showing that it includes the correct device iPhone4,1
以下是来自 iPhone 4s 的用户代理字符串，显示它包含正确的设备 iPhone4,1

The devices shown seem to follow the same model identification shown in an answer on detecting iOS models
