Can you determine if Wifi security is enabled on network you're connected to on iOS?

In my iOS app, I'd like to be able to determine whether the Wifi network the device is currently conne开发者_StackOverflowcted to has Wifi security of some sort enabled (wep, wpa, etc).

CaptiveNetwork provides the SSID of the connected network, but not much else.

Is there an approved way of determining if WEP/WPA/etc are enabled on the currently connected Wifi network?

Apple is not providing any Wifi related API and all the information that is available to you is given by the actual network, so basically you cant access this information.
