iOS wifi scan, signal strength
提问by momo
As far as I know it's not possible to scan for hotspots in range and read their bssid and signal strengths. This was possible on iOS 4 by using private APIs and not longer possible on iOS 5 without jailbreak. Even if it were possible, the app would be rejected on the App Store. Is that right?
据我知道这是不可能的扫描热点的范围和阅读他们的BSSID和信号强度。这在 iOS 4 上可以通过使用私有 API 而在没有越狱的 iOS 5 上不再可能。即使可能，该应用程序也会被 App Store 拒绝。那正确吗？
One company that has an indoor positioning system is claiming they can develop this system in iOS. I know for a fact they are scanning for hotspots and signal strengths and then triangulating the signal on their current Android app.
一家拥有室内定位系统的公司声称他们可以在 iOS 中开发该系统。我知道一个事实，他们是在扫描热点和信号强度，然后三角他们目前Android应用的信号。
Are there any alternatives I am missing? Their claiming sounds impossible to me but I would love to hear from the people here. I would like to be ready when they demo (although I am expecting a jailbreak or some kind of mock up)
有没有我缺少的替代品？他们的说法对我来说听起来不可能，但我很想听听这里的人的意见。我想在他们演示时做好准备（尽管我期待越狱或某种模拟）

As far as i know this can still be done (using private APIs, of course) by MobileApple80211 framework.
据我所知，这仍然可以完成（使用私有的API，当然）MobileApple80211框架。
Stumblercode is a good source of information on how to use this framework.
Stumbler代码是关于如何使用这个框架的一个很好的信息来源。
For iOS 5 you'll need a jailbroken iPhone. Guvener Gokcehas a very educational blog post on this: iPhone Wireless Scanner iOS5
对于 iOS 5，你需要一个越狱的 iPhone。Guvener Gokce有一篇非常有教育意义的博文：iPhone Wireless Scanner iOS5

Just to update the answer: The MobileApple80211 framework has been replaced by MobileWifi.framework. You will need a jailbroken device (supposedly it can't be done using just private API's, hence on a development/enterprise non-jailbroken device).
刚刚更新了答案：MobileApple80211框架已取代MobileWifi.framework。您将需要一个越狱设备（据说它不能仅使用私有 API 来完成，因此在开发/企业非越狱设备上）。
