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;

   }

Solution

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: github.com/moshegottlieb/SoundSwitch
