Issue embed YouTube player in a UIWebView when Restriction applied on device

[erritikamathur]

i have been using UIWebview to play youtube video inside my application

This works fine.But user can allow/disable access to youtube app through Settings app

In Setting app,General ->Restriction ,disable Allow for Youtube app
Now UIWebview load youtube with play button crossed,user cant play video.
My console complaing that YouTubePlugIn not found on device
This issue occur on both iPad & iPhone.

on disk is:
    /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.3 (8J2)/Symbols/System/Library/Internet Plug-Ins/YouTubePlugIn.webplugin/YouTubePlugIn (file not found).
warning: No copy of YouTubePlugIn.webplugin/YouTubePlugIn found locally

How can i know that UIWebview can load youtube url before loading?
That is how could i know that youtube app is Restricted access on device?
