Detect silent mode in iOS 7

Question

is there any way to detect silent mode in iOS 7?

the following code does not work for iOS 5 or later version

-(BOOL)silenced {
     #if TARGET_IPHONE_SIMULATOR
         // return NO in simulator. Code causes crashes for some reason.
         return NO;
     #endif

    CFStringRef state;
    UInt32 propertySize = sizeof(CFStringRef);
    AudioSessionInitialize(NULL, NULL, NULL, NULL);
    AudioSessionGetProperty(kAudioSessionProperty_AudioRoute, &propertySize, &state);
    if(CFStringGetLength(state) > 0)
            return NO;
    else
            return YES;

   }

Check this thread - Detecting the iPhone's Ring / Silent / Mute switch using AVAudioPlayer not working?

And this API - SoundSwitch

How it works:

Play an audio file of 0.5 secs, every sec (after completion..)
Check how long it took to play the sound
Callback called real fast? nothing was played (silent switch is ON)

Enjoy!

The link above no longer works. Here's the github version for a sample project: https://github.com/moshegottlieb/SoundSwitch – Moshe Gottlieb Dec 15 '16 at 08:55
